- What brands are offered by DiscountSheds.com.au?
Discountsheds.com.au offers quality Australian made gardens sheds, workshop sheds, patio awnings, carports, garages & aviaries – from the country’s leading manufacturers, including: Absco, Oldfield’s Treco, Stilla, & The Outstore.
- Absco Sheds - What's all the fuss about!
ABSCO Industries is a wholly owned Australian company manufacturing a large range of steel products including Garden Sheds and Outdoor Buildings. From its manufacturing facility in Brisbane, ABSCO distributes an extensive range of outdoor storage products throughout Australia, as well as exporting to the Pacific region and Europe. ABSCO Industries has been the major supplier of these products to the hardware and outdoor building industries for over 40 years. The good reputation that has built up during those years is now being recognised throughout Australia and rapidly expanding overseas markets, including New Zealand and Europe.
Through its superior organisation, ABSCO Industries can claim the enviable reputation of being the leader in maintaining supply of its products to its customers “ALL products are ready for despatch ex factory within two working days”. Absco is the market leader, certainly in Australia, if not the world, for our innovative designs and our range of garden sheds and other products that incorporate the world patented SNAPTiTE Easy to Assemble System”. The ABSCO SNAP-TiTE system is revolutionary because it dramatically reduces the number of fasteners needed to assembly a garden shed. Many average size garden sheds require over 600 screws, nuts, bolts, and rivets to be fitted, whilst with some others, holes must be drilled during assembly. Compare that with the innovative SNAP-TiTE system, which makes DIY construction very easy, because it uses only 200 fasteners to assemble an average size garden shed! Not only does the SNAP-TiTE system make assembly easier and faster, the end result is also significantly stronger. ABSCO has put the SNAP-TiTE system to the test too, demonstrating superior strength in laboratory tests carried out to international ISO standards. That’s because the revolutionary SNAP-TiTE system features significantly more anchorage points between the wall section and edge channels. Compare that with the average garden shed and you’ll see why! With SNAP-TiTE every corrugation on both sides of all wall sections, feature a punched lug which locks into the patented edge channel to maximise strength. Naturally, the benefit that the SNAP-TiTE system delivers by dramatically reducing the number of fasteners, translates to enormous savings in the time it takes to assemble a typical garden shed. With other brands, a whole weekend can be spent completing the installation. Compare that with the innovative SNAP-TiTE system, which enables the average home handyperson to complete the task in only a couple of hours! The revolutionary SNAP-TiTE system not only makes assembly faster and easier, it also helps deliver a professional finish. That’s because the snap-fit design of the wall and channel sections takes out the guesswork. With typical garden sheds these components must be aligned, drilled and fixed together with unsightly screws, rivets, or bolts. Compare that to the SNAP-TiTE system, which aligns and snaps components together perfectly, without the need for drilling and fitting rows of fasteners!
- Where are the sheds manufactured?
All metal sheds sold by Discountsheds.com.au are proudly manufactured in Australia, by Australian owned companies. Some exclusively use Australian Bluescope steel, whilst others may use either Bluescope steel or imported steel (to offer a budget market entry price). The range of resin sheds sold by Discountsheds.com.au, are distributed nationally by The Outstore. These sheds are fully imported & are relative newcomers to our market. They have however been available & extremely popular in North America & Europe, for many, many years.
- What are the product warranties and how do I register my warranty?
Each manufacturer offers their unique product warranty, both in its terms & conditions, as well as the period of time covered. Please refer to the product information detail for specific information. One of the most comprehensive manufacturer’s warranty is from the Absco brand. Absco exclusively use Bluescope Colorbond® or Zinclaume® steel in the majority of their product range and offer a thirty (30) year warranty. Recently a budget “Eco-Nomy” Range has also been introduced, that uses imported steel & offers a ten (10) yr warranty. If you purchased an Absco product, log onto the manufacturer’s web site at www.absco.com.au and select the “Register Warranty” button on the top navigation bar to the home page, & follow the prompts. For other manufacturer’s, the warranty form will be included with the delivered product, for your due completion & submission via postal services.
- What is the difference between the different finishes or colours on the steel sheds?
What is Zinclaume®? Zincalume is a registered trademark name of Bluescope steel’s galvanized steel. It has an alloy treatment applied to sheet metal that delivers the steel its long lasting properties. It has a silver satin like finish.
What is COLORBOND® steel? COLORBOND® steel combines the corrosion resistance of a ZINCALUME® steel base with a durable, oven baked paint finish.
Only genuine Australian (BHP) Bluescope high tensile steel products are able to use the names Zinclaume or Colorbond. Where the descriptions of “Zinc or Colour” (instead of Zinclaume or Colorbond) are used, the steel used by the manufacturer is not Bluescope & the generic descriptor(s) are used to comply with trademark legal requirements.
- What is the gauge of steel used?
Various manufacturers may and do use different gauge materials, compared to each other. They procured the steel sheeting from various global sources. This allows them to present a range of fit-for-purpose products, offered at different retail price points. Absco Industries exclusively uses Australian Bluescope steel in their legacy & foundation range products, as well as an imported steel range (for the budget minded). As an generalisation and guide, the imported steel manufactured products are offered with a comparatively lesser life warranty. 20 or 10 year warranty Vs a typical 30yr warranty for Bluescope steel products. Structural capability is a function of the steels’ base metal thickness & the grade & tensile strength of the steel’s composition. The anti-corrosion performance of the steel is delivered to the product by the type & thickness of the metallic coating used by the steels’ manufacturer. To this end, the Australian Standards as referenced by the BCA (Building Code Of Australia) specify minimum compliance thresholds. When doing comparisons, always remember the differentiation between the published thicknesses. BMT or Base Metal Thickness is the thickness of the steel without any metal coatings & where applicable, primer & colour coatings. TCT or Total Coated Thickness, is the thickness including protective & finishing coat applications. These coatings or applications are usually .05mm thick in themselves. Although they are included in a published TCT gauge thickness, they do not contribute to structural steel strength. Therefore a 0.35mm TCT gauge offers no more structural strength than a 0.3mm BMT gauge steel sheet.
- Whats up with all the wind rating references?
A products published wind rating represents what the engineered design wind withstanding tolerance, is. Each supplier designs, engineers & manufactures their products independently. Having said that, most sheds* (*although not all models) are engineered to a W33 / N2 rating (to withstand winds of up to 118 klm). Other non-shed products (awnings, carports, garages etc) are usually offered in various wind ratings ranging from W33 / N2 or higher. This enables the customer to find a product applicable to the local authority & building code compliance requirements of their area and specific installation address. Refer to each product’s specifications/details for further information.
What wind rating do I require for the product I wish to purchase? Required wind ratings can & do vary across Australia. In fact they may vary within city limits or even from street to street. It is highly recommended that you contact your local authority, to ascertain what is required at your physical address, before you make your purchase. Under Australian Standards AS4055, the geographic area of Australia is split up into a ten-band wind classification system, from N1 – N6. These bands are assigned to various regions. The requirement for your address depends upon a combination of factors from your location/region within Australia, to the shielding / buffering effect of the surrounding terrain & topography.
- Local authority / council approvals
Regulations vary amongst local authorities in Australia. However most require the homeowner to apply for approval for any structure that covers the ground more than 10 square meters. (E.g. an item that is 3m x 3m or 10ft x 10ft shed is approx 9 sq meters & would be exempt). To make yourself aware of any possible restrictions or other compliance issues, please check with your local council & ascertain what their requirements are & where applicable, what the process & costs for approval, are. Although not common, be aware that for items that require approval, size may not be the only factor governing where you can position your product. There may also be considerations regarding how close you can erect your product to boundary fences, sewers, storm water, mains, easements etc. Where applicable, all council building approval compliance requirements should be satisfied before any purchase is made.
- Can I install the shed by myself?
All products offered for sale on this Discountsheds.com.au web site are designed and manufactured for the DIY’er. Historically, more than 70% of shed products sold in Australia are erected & installed by their purchasers.
Each manufacturer’s design & assembly protocols differ and result in varying comparative assembly times. Each product is supplied with concise & easy to understand & follow assembly instruction manuals.
Always allow sufficient time to complete the task, & only commence the assembly during favourable weather conditions.
Although the sheds are designed to be assembled by a single individual, another pair of hands always helps.
- What is the difference between the various roof configurations mentioned?
A GABLE roof is a roof with a raised peak at both ends. This allows the roof to slope in two directions. In garden sheds, the gables can be located at either the front & back walls… or the side walls. Where the gables are in the front & back walls of the garden shed, the roof slopes (or falls) from the middle to either right & left side (much like the profile of a house). Where the gables or peaks are in the side walls, the roof will slope from the middle high point towards the front (above the door) and from the middle towards the back.
A SKILLION roof falls or slopes in one direction only. Typically it will slope from a high point at the top of the rear wall, downwards towards the front wall. In some models however, the skillion roofs can be reversed or fall from either side wall (refer to individual product details).
A FLAT roof is simply just that, flat. This roof has no fall. However the corrugations of the sheeting assist in the prevention of pooling water. The roof also has a generous side overhang. This also assists in preventing dripping water tracking on the underside of the roof lip & into the inside of the shed. (refer to individual product details).
- What accessories and options are available?
The main retailed options/accessories that are available for your garden shed, are –
- Anchoring / bolt down kits
- Skylight roof sheets
- Insulation blankets
- Cyclone conversion kits
- Shelving units
- Modular timber floor kits
These vary according to manufacturer and range – Refer to each product’s details for further information.
- Are assembly instructions easy to follow?
Each manufacturer puts together their own assembly manuals which are of course supplied with the products. They all share the common goal of providing a concise, easy to read & comprehend, list of instructions that are designed to make the task of assembly efficient and easy for the do-it-yourself handyman. Where available, discountsheds.com.au has provided assembly videos, which can be found in each product page and the Shed TV section of this web site. Please keep the manual for future use.
- What tools are required to assemble my garden shed?
- Cordless drill or screwdriver
- Hamer drill may be required if penetrating concrete to fix bolt-down anchors (dyna bolts)
- Tape measure (to aid in the identification of parts by checking lengths & to ensure walls are ‘square’ on the diagonals)
- Step ladder
- Rivet gun
Anything Else ???
- A Smile
- Good music
- Allowance of enough time to complete (avoid leaving it 1/2 done)
- Patience to read, understand & follow the assembly intructions
- 2nd person always helps
- Avoid windy days
- What is the best way to secure a garden shed to a base?
Your shed must be adequately fixed & secured to a base to ensure it does not blow away or move in inclement weather conditions. It is a generally accepted practice & one recommended by the manufacturer’s, that dynabolts or similar be used to secure a garden shed to a concrete slab. Each manufacturer designs their sheds in their own unique way. Some merely require the appropriate size dynabolt to be used fixing through the sheds’ existing perforated base channel, others require an anchoring/fixing bracket & dynabolt, and others again include all masonry anchors & fixings required, with the shed. Where the shed is to be situated on a timber deck, concrete pavers or other type of surface; please ensure that both the shed & the base are adequately secured to the ground. As always, follow each manufacturer’s recommendations.
- Do I need to seal the base of my garden shed?
Where required or desired, sealing the base of your shed can be accomplished using the appropriate professional grade & quality, silicone sealants. Neutral Cure silicone rubber sealants are the only sealants recommended for use with COLORBOND® steel and ZINCALUME® steel. Look for the words “Neutral Cure” on the sealant cartridge to make sure. Always follow the maufacturer’s instructions & always ensure both the surface areas of the slab & shed are thoroughly clean & free of dust, oils, & other contaminants (to ensure the best possible surface for bonding). Please remember, if water does get into a sealed shed (through windows, doors, or other entry point), you are also traping it in. Graphic below depicts anchoring & silicone sealing of an Oldfields Treco Shed (for illustrative purposes only)
- Deliveries - How does it all work?
Logistics: What are the delivery options? Delivery options vary by manufacturer. The products are made, held & dispatched by each manufacturer. The manufacturers consigns the order(s) for delivery with their national contracted freight carrier & their networks. Some manufacturers offer both free delivery to nominated freight depots throughout Australia (for customers to pick their orders up from) or paid delivery to their door. Others only offer paid delivery to your door. Please refer to the specific delivery options & processes, noted in each individual product page, in this web site. For estimated dispatch time frames – please refer to the “Availability” notice in the “Specifications: Snapshot” tab of this product page. Note, this advice is an estimate only and is the best and most current notification as provided by the manufacturer. This estimate may vary and be subject to change. Although certainly the exception to the general rule, at times, the manufacturer may experience unforeseen production or dispatch circumstances, which may result in extended times required to fulfil an order. Allowance also needs to be made for the time required for the shipping & handling of the order. Delivery times vary based on the freight companies handling volumes, the ordered product size and delivery destination. Once you order arrives at the closest freight distribution centre to your location, the freight carrier will call to either:
- Inform you of your orders availability for your pick up (if that is the option you have selected) or
- To co-ordinate with you the home delivery arrangements.
Logistics: How long will it take to receive my product? It is recommended to allow an estimated minimum of 25 working days, for dispatch & delivery of most goods by the manufacturers (although in many cases this may be much less). This time frame applies to garden shed products – Carports, Garages & Awnings will take longer (up to 55 working days for production, dispatch & delivery – unless otherwise noted based on specific manufacturer dispatch & delivery times). Discountsheds.com.au utilises the nationwide freight & delivery networks of our supplier partners. As such, the process differs & is dependent upon the brand of product you have selected. This is covered in the shipping & delivery section of the product you have or may select. Please Note: In order for the manufacturers’ and their freight carrier agents to keep costs down, all home delivery costs for garden sheds & aviaries are now calculated and offered as ASSISTED DELIVERIES. That means that the customer must ensure an able bodied person is present to receive and assist the delivery driver with the unloading of their shed order. In addition, the property must be able to accommodate appropriate access for the freight carriers tailgate truck (in order to avoid the cost of attendance to the premises and not being able to complete the delivery). Failure to do so MAY incur additional delivery & handling fees. These additional fees may be levied by the manufacturer & their freight carrier agents, & charged to the customer by Discountsheds.com.au. These costs start but are not limited to $90 plus GST. All deliveries are to the front of the property only. Delivery of Carports / Garages / Patio Awnings are NOT Assisted Deliveries. No unloading assistance by the customer is required. Additional labour and larger delivery trucks with crane attachments, are used to offload these large items, that are delivered as single pallet bundles. These additional freight servicing costs are reflected in a increased delivery fee levied on these items
Logistics: How Do I Track Down My Shipment? When your order & payment is processed by discountsheds.com.au, (usually by the next working day) you will be emailed a tax receipt. This receipt, will confirm the product ordered. Where your nominated delivery destination is a freight depot, the physical address & contact details of the freight depot to which the product(s) is to be delivered, will also be noted (for your records and action). Upon receipt of the goods, the collection depot nominated, will contact you directly so that you can make your arrangements. Please do not prematurely contact the collection depot with inquiries, as they will not have a record of your purchase until it arrives into their possession. Allow an estimated 25 working days for delivery of the goods, by the manufacturers, for all garden shed products. Carports, Garages & Awnings will take considerably longer (refer to the specific product shipping & delivery advice in that items product page). If you have any questions regarding freight & shipping, or your order has not arrived within the 21 days, please do not hesitate to contact us on 1300 834 738 or email at email@example.com, with your order details, for our follow up
Logistics: Can I go to the freight depot & pick up my order after I’ve ordered it with you? No. If the depot delivery option is selected, you order will be delivered there after the manufacturer dispatches & consigns your order. Upon your orders arrival and processing at the depot, the freight carrier will contact you to notify its availability for pick up. Packaging dimensions, configuration & weight – of your ordered product, is listed in the “Specifications: Snapshot” tab on this product page. Please note, these locations are freight depots, only. They are destinations where your order gets delivered to FREE OF CHARGE, for your pick upon notification of its arrival from the manufacturer. They are not warehouse facilities that keep un-ordered catalogue products in stock. The depots will only hold on to your delivered order for a few days (usually no more than 3-5 days), allowing you to pick it up. Failure to pick up your order within this period may result in storage and handling fees to be levied, as these depots are not storage facilities. Should these fees be charged by the freight carrier, this impost will be charged through to the customer. Depots are open for your pick up during their Mon-Fri weekday business hours. Please check with the depot you may potentially select, for specific hours (as they may vary across Australia).
- What should I do when I receive my order?
Whether you are picking your order up from the depot or are receiving your order at home, it is extremely important that attention is paid before you sign for and receive the goods. Signing for the goods denotes the customer has received all goods as ordered & that they are in a good and fit condition. Even though great care is exercised by both the manufacturer and their freight carrier and agents, in some circumstances, the goods may either be damaged in transit, or be issued in error or incomplete. The following steps should be followed to ensure you are receiving the complete product you have ordered:
√ Check the product/model no. on all box labels, to ensure it agrees with the item you have ordered (this information is noted on your web order confirmation and emailed tax receipt) √ Check the box labels to verify that all the boxes that make up your model no. are presented. Box labels will show how many packs make up that model. For example – The box label will shown the Model No. & then state that the particular box is number __ from a total of __. If the label says that the box you are looking at is pack 1 of 2, then there should be a second pack. Please check that second box/pack to ensure it is the correct one for the ordered model, by checking the model number shown.
Damages & Shortages: Within thirty (30) days of the receipt of the goods, you should inspect the product(s) in its entirety. The inspection is to satisfy that the product is in sound condition & is complete. You must notify discountsheds.com.au (the retailer) of any fault, damage or shortages of the goods and their component parts, so that we may comply with the manufacturer’s policies and allow them to initiate corrective measures, where required. Do not attempt to assemble the product until you are in possession of all required components. This is ascertained by following the manufacturers’ written general instructions in the assembly manual. Carefully unpack the carton(s). Identify and check off the included parts and components against the parts illustrated and described in the manual. Partial and incomplete assembly (whilst waiting for the supply or re-supply of any reported missing or damaged parts) may result to damage to the structure, for which the retailer and the manufacturer are not responsible for.
Although great care is employed by both the manufacturer and their freight carrier and agents, errors in dispatching the product or damages incurred in transit, may occur. In order to rectify and resolve this issue expeditiously, the shortage or nature of the damage should be reported in as much detail as possible. In order to initiate the supply or reissue of missing or damaged components, the manufacturer’s require the following in a written email, for their action –
- The email is to reference your Discountsheds.com.au Tax Invoice/Receipt Number (as emailed to you by Discountsheds.com.auupon processing of your online or phone order). Note this is different to the automatically generated web order ID. It allows us to identify your order & index it to the manufacturers reference number for your transaction.
- The email is to list any and all, missing or damaged parts that require reissue or replacement (tabled in one correspondence). This information must be sourced & noted from the products assembly manual components list, as follows: Quantity, Part Description, & Part No.
If a claim is being made for parts that are damaged, the manufacturers require photos to be attached to your email, that clearly show the damage referred to. Please include adequate detail in the photos for the manufacturer to review the nature and extent of the damage. Photos from afar ( a few steps back showing damages to packaging ?), as well as close up detail, to show damage to parts – would be ideal. For Absco products, the email is also to include photo(s) of the production information label both on the box and stamped on the internal parts (see example photos below). Please make sure this is done before packaging is destroyed / disposed of / or possibly perishes in the weather. These submissions are requested & required by the manufacturers. It is important for their quality assurance program and where applicable, their possible freight insurance claims. (Example only shown below)
- What if I want to change or cancel my order?
Logistics: Order Cancellations & Alterations If a processed & confirmed order is cancelled or revised by the customer – service charges may apply. Where applicable, if the item(s) ordered has at the time of the customer request already gone into manufacture or has been dispatched for delivery and needs to be sent back because of a cancellation or alteration to the original order , the customer will be liable to the following services charges : (A) A 25% restocking fee (this cost is levied by the manufacturer & passed through to the customer), (B) All return freight costs (this cost is levied by the manufacturer & passed through to the customer) & (C) up to a $150.00 administrative fee (representative of but not limited to additional processing costs incurred). The service charges, represented by the restocking fee, product return freight costs &/or administrative fee – will be deducted by discountsheds.com.au from the order / transaction value. It is the responsibility of the customer to retain possession & take reasonable care of the goods (with undamaged packaging), until the goods are returned to the the manufacturer or their freight carrier/agent. Upon return, the manufacturer will make a determination if the product is found to be sound, complete & as described for sale. If the manufacturer accepts the return, they will subsequently advise discountsheds.com.au & issue discountsheds.com.au a return credit (nett of the product return freight charges & restocking fees). Discountsheds.com.au upon receipt of this manufacturers nett credit , will within 30 days, process a refund reimbursement to the customer nett of the manufacturer’s product return freight costs, the 25% restocking fee & Discountsheds.com.au’s up to $150.00 administrative processing fee. Logistics: Returns – Change Of Mind Where the customer has changed their mind &/or consider the product they purchased unsuitable for their needs or space requirements, it is the responsibility of the customer to meet all service charges, represented by: the product return freight costs, the 25% restocking fee, (both levied by the manufacturer) and up to a $150.00 administrative fee (representative of but not limited to additional processing costs incurred). The restocking fee, product return freight costs and any administrative fees – will be deducted by discountsheds.com.au from the order / transaction value. It is the responsibility of the customer to retain possession & take reasonable care of the goods (with undamaged packaging), until the goods are returned to the the manufacturer or their freight carrier/agent. Upon return, the manufacturer will make a determination if the product is found to be sound, complete & as described for sale. If the manufacturer accepts the return, they will subsequently advise discountsheds.com.au & issue discountsheds.com.au a return credit (nett of the product return freight charges & restocking fees). Discountsheds.com.au upon receipt of this manufacturers nett credit , will within 30 days, process a refund reimbursement to the customer nett of the product return freight costs & the 25% restocking fee & Discountsheds.com.au’s up to $150.00 administrative processing fee.
- Shed Maintenance
How can I clean COLORBOND® steel? For information on how to keep your COLORBOND® steel looking great, view our page Maintain COLORBOND® steel and ZINCALUME® steel. If you think you may have fungus growing on the surface, view the Identify and Remove Fungus page from the Bluescope steel “Colorbond” website – http://www.colorbond.com/ How do I fix a scratch on Colorbond® Steel? The recommendation is not to touch up. Minor scratching will not effect the life of the sheet and is rarely obvious to the casual observer. The use of aerosol touch-up sprays usually result in overspray & whilst not imediately obvious, the sprayed on colour may weather at a different rate to the oven-dried paint on Colorbond® Steel. From Bluescope steel “Colorbond” website – http://www.colorbond.com/ How can I prevent condensation forming on my roof? Condensation forms under/on roof sheeting when the sheeting becomes colder than the air in contact with it. Water vapour carried in the air then condenses on the colder surface of the roof sheet. To minimise the risk of water damage to ceilings or corrosion related to condensation under steel roof sheeting, a vapour barrier should be provided under the sheeting to prevent contact between the moist air in the building and the roof sheeting. Reflective foil laminates (sarking) which are commonly used to provide heat insulation under roof sheeting can serve a dual function as a vapour barrier, by thoroughly sealing the foil overlaps with moisture impervious adhesive tape. The laps should be about 100 mm and kept in close contact when positioning the laminate so the tape can be readily applied. The laminate must be allowed to drape between the roof supports so that the cold temperature of the roof sheeting will not be transmitted to the laminate by contact. If this were to happen condensation could form on the underside of the laminate and may drip into the ceiling space. Ventilation of the ceiling cavity may assist in the reduction of condensation however it has been shown that ventilation will not completely eliminate the condensation cycle. In certain marine situations ventilation may also carry salts into the roof cavity which will, in the presence of condensation, lead to accelerated corrosion attack. From Bluescope steel “Colorbond” website – http://www.colorbond.com/ Can I use touch up paint on COLORBOND® steel? BlueScope Steel does not recommend the use of touch up paints on COLORBOND® steel. The manufacturing process that gives COLORBOND® steel its colour and gloss retention properties means that the surface weathers differently to air drying paint. After weathering, the areas which have been touched up will look different and can leave a blotchy look. From Bluescope steel “Colorbond” website – http://www.colorbond.com/ What sealants (silicone) can I use with COLORBOND® steel? Neutral Cure silicone rubber sealants are the only sealants recommended for use with COLORBOND® steel and ZINCALUME® steel. Look for the words “Neutral Cure” on the sealant cartridge to make sure. From Bluescope steel “Colorbond” website – http://www.colorbond.com/
- How much concrete will I need?
When determining the size of the concrete slab you will need to pour for your new shed, it is important to refer to the manufacturer’s recommended minimum slab dimension requirements. In most cases, this recommended minimum will be the exact external base dimension of the shed, plus an additional 100mm in each direction. For example, if you purchased a shed whose base is exactly 3.0m x 3.0m, then the minimum slab should be – 3.1m x 3.1m. It is recommended that slabs be 100mm in depth or thickness. Calculation:► The amount of concrete required is calculated as metric “Volume” (or m3 unit of measurement). Note: “Concrete” is the final blend of cement, sand, gravel, & water components. To calculate how much concrete is required, simply multiply the following – A. Length (dimension across the front) of the required slab (in meters) x B. Width (dimension down the side) of the required slab (in meters) x C. Depth (dimension of the thickness) of the required slab (in meters) For Example – Using the above slab dimension of 3.1m x 3.1m that is 100mm deep or thick… the calculation would be – A x B x C or 3.1m x 3.1m x 0.1m. This gives us a result of 0.96 m3 Notes:
- Calculations do not allow for waste. Typically a 3-5% waste factor will need to be allowed.
- Calculations assume flat & level ground. They do not take into consideration fall or dips in the ground. The presence of these factors will require allowance for additional concrete or fill.
Concrete Options:► Ready-Mix Concrete This is the most cost effective option for larger jobs. Most suppliers will deliver smaller quantities with minimum loads from 0.3 of a cubic meter. Be sure to discuss the use of the concrete (for a shed slab) with the supplier, so that the appropriate strength of concrete is used. Pre-Blended Concrete Dry Mix Bags These pre-blended bag mixes contain cement, sand, & aggregate – just add water. This option is worth considering for those small jobs or where access is restricted. Bags are typically available in 20kg packages. The number of bags required, usually surprises people. For medium to large sheds, the number required is quite large & as such is cost prohibitive. One 20kg premix bag generally provides 0.11 of a cubic meter (or 110 20 kg bags to provide 1m3) Hand Mix Requires far more effort, but is by far the most cost effective option. Here, you will be required to purchase sand/gravel, cement, & perhaps hire of a concrete mixer. How Big Does My shed Need To Be To Fit My Items Every care has been taken to provide this information. It is intended fro general reference only. Please verify content & calculations with the concrete products supplier.
