Our range of plastic garden storage is ideal if you need to store smaller items like bicycles, children’s toys or garden tools. Constructing a wooden shed is fairly simple and only requires basic DIY but here at Shed Supermarket we stock an Easy Fit Sheds. The building should be in a clear space so you are able to access all areas of the shed to apply a timber treatment. At Shed Supermarket we are committed to sourcing our materials from responsible and manageable forests. Clean off the underside of the roof panels with Methylated Spirits and ensure that they are fully dry. Concrete is often overlooked as a potential pavement surface, mostly because of its lack of colour or interest, although the decorative patterned concrete is becoming more popular and cementitious overlays offer a huge range of colours, patterns and textures. Plain concrete can be very useful in areas where a decorative look is not required, such as caravan hardstandings, shed and garage bases or dog kennels. Modern concrete technology has led to the development of fibre reinforced concretes that create high-strength pavements without the need for steel reinforcement mesh.
Given good ground, mass concrete can be placed directly onto a damp-proof membrane over the prepared sub-grade.
Concrete paths should be 75-100mm thick, whereas drives, garage bases or hardstandings should be at least 100mm thick. The purpose of the dpm is two-fold: Firstly, to protect the underside of the slab from attack by dampness and aggressive salts (such as chlorides) or other chemicals in the sub-base or sub-grade, and damaging the concrete, unseen, from beneath. Any 'laps' required in the membrane should overlap by at least 350mm, and preferably be taped down to prevent ingress of ground water or egress of mix water.
Reinforcement in concrete is used to ensure that the cracking which always occurs does not threaten the structural integrity of the concrete. Movement joints (expansion joints, contraction joints, isolation joints, crack control joints, etc.) are used with concrete slabs to protect the slab itself from cracking, to accommodate the inevitable movement of the slab and to prevent excessive forces being transmitted to adjacent structures.
A shovel or a strong rake is used to roughly level out the wet concrete, and then a straight-edged timber can be used to tamp down the concrete to the correct level.
Vibrating poker units can be used to expel most of the unwanted air pockets, and so-called 'Bug Rollers' are useful for making sure any hard aggregate is pushed into the concrete, although this is more important on PIC than plain concrete.
For larger projects, Hire Centres can supply Vibrating Beam Screeds and Roller Strikers that are dragged over the roughly levelled out concrete, vibrating it to eliminate air pockets, pushing surplus concrete in front of the beam, and levelling, all in one operation. A reasonably smooth surface can be obtained by repeatedly tamping wet concrete, but for a finer finish, the surface should be smoothed using a steel float trowel. Judging exactly when to commence floating, either with hand tools or with a power float, is an art in itself, and is gauged from years of experience; too soon and the trowel marks will never disappear, too late and the concrete might not 'rub-up' to a close finish. A perfectly smooth concrete surface can become quite slippy, especially outdoors in wet or icy conditions. On light-use applications, such as driveways, garage bases and the like, there is a tendency to leave the concrete, once the finishing has been done, to harden and cure at its own pace. Temperature control is only a serious issue when there is a risk of the ambient temperature falling below 4°C.
In winter, freshly poured concrete may be protected with hessian sacking, straw or polystyrene to insulate the slab overnight. Formwork and shuttering can be removed from a concrete slab after 24 hours, although it is often left for 3 days unless there is a need to examine the edges.
The keeled garage slab cross-section is provided as an example of a typical detail and NOT a recommendation.
Pre-fabricated sectional garages can often be erected on a simple 150mm slab, such as that shown above; this keeled slab is the type of raft foundation that may be used with a single brick construction garage. Whilst not the most attractive type of pavement, a well laid concrete area should give many years of maintenance free service.
Your slab will be 50mm thick (not including the trench around the edge) and you want it to rise 20-30mm above the level of the surrounding ground to stop water running into the shed.
Important: We recommend you set anchor bolts into the edge of the concrete immediately after you pour the slab.


Because this is a relatively small concrete slab, you should have time to place all the bolts after you pour the slab but before you work the surface of the concrete with your trowel. Refer to the plan and make sure you don't place any bolts where the doorway will be or below a vertical beam. A concrete shed base is without a doubt the strongest and most durable form of shed foundation. With Instructables you can share what you make with the world, and tap into an ever-growing community of creative experts. Extra storage space is always welcomed around the house even if you do not have any kids or college students around. Thanks for sharing your detailed step-by-step DIY guide, especially the part about filling in the sloped ground area. Most of our metal shed come with a manufacturer’s guarantee against rust and are made from durable, modern materials. The base needs to be level so it can support a garden building evenly.An unlevel base can cause a building to sag or crack.
Easy Fit Sheds are available in four sizes and are made from high quality tongue and groove cladding. Adhere polystyrene tiles to the underside of the roof (these do not have to be high quality tiles) using a spray adhesive suitable for sticking Polystyrene to metal and that is not adversely affected by the heat or cold. Your local ready mixed concrete supplier will advise on the most suitable type and strength of concrete for your project. For heavier applications, or on bad ground, it may be advisable to construct a sub-base of compacted granular material or lean-mix concrete beneath the actual concrete slab, or to lay a sub-base over a geo-textile.
To calculate the required amount, simply multiply length in metres by width in metres by depth in metres to calculate a volume in cubic metres.
Tamping helps eliminate air pockets being trapped in the body of the concrete and also helps to push the hard aggregate into the concrete, bringing sufficient of the matrix to the surface to make smoothing (floating) easier. 3 or 4 passes with a beam screed is usually sufficient to give an acceptable finished level, with a tolerance of ±6-10mm. This is best done when the concrete has started to stiffen as part of the hardening process, as the float trowel leaves fewer trowel marks. It is recommended that once the surface has been smoothed with the float trowel, light brush strokes be made over the surface, transverse to the direction of travel, to improve traction once the concrete hardens. It is usually checked after 10-12 hours, just in case any immediate repairs or 'rubbing-up' is required, and while this may be satisfactory for small jobs, larger slabs, especially those where the final strength is critical, require careful management of the critical first stages of curing if they are to meet their design targets. It is unusual for concrete to be poured in harsh weather conditions, that is, when the ambient temperature is below 4°C and falling, unless there are extenuating circumstances.
Care must be taken when striking the formwork to avoid damaging the concrete which will still be 'green', as we call it in the trade.
Although reinforcing fabric mesh is not essential in concrete slabs, it does strengthen the concrete and is something we always recommend. This can be quite tedious, but it is the best way to attach the frame of the shed to the floor in our opinion.
In larger jobs the bolts would have to be placed first and the concrete poured around them. For a wooden floor, lay four 2.2m lengths of treated 100mm by 75mm timber down on your flat site. My wife has been asking me to build a storage shed to put my things in (she's a neat freak).
I have always wanted to make some space and storage for some of my items in the garage and at home.
Our backyard is similar to yours and we have been contemplating on the various materials to use to level up the sloped ground area.
A great tip for choosing the right shed is to write a list of everything you want to store in the shed. Tongue and Groove Sheds are perfect if you’re looking for a durable and high quality garden shed. Fix the shed to the wooden floor using both wood screws and mastic seal on the inside of the shed base rails.


Both tiles and roof panels need to be coated in the spray and then as per the instructions (usually left for a minute or two) the surfaces can be bonded together.
By combining plain concrete with a decorative edging, such as a brick edging, it can be made to look quite attractive.
On soft or unreliable ground conditions, a sub-base will help spread the load of a mass concrete slab, but in such conditions it's best to obtain a professional opinion from a civil or structural engineer.
Concrete slabs intended for exceptional loads, such as commercial yards, lorry parks etc., will be at least 200mm thick and should be specifically designed as they will probably require a sub-base of at least 100mm thickness, and steel reinforcing mesh or a fibre-reinforced concrete. Builders' merchants normally carry 'visqueen' or PIFA 1200 as an off-the-shelf product, as it is much used throughout the construction industry.
Ready mixed concrete companies usually deliver in multiples of half-cubic metres, so "round-up" your calculated quantity accordingly. The ready mixed concrete supplier will understand these references, and the delivery wagon usually carries extra water that can be mixed into the concrete before pouring, if the mixture is too stiff. Hand floats, also known as Bull Floats, are fine for small areas where a near-perfect finish is not essential. Additional space heating may be provided in such situations to keep the ambient temperature above the 4° threshold. In most cases, a concrete slab should be kept completely free from all traffic for the first 48 hours. Fibre reinforcement may be used in place of, or in addition to, the steel mesh in the plain slabs. Although there are other ways to attach structures to concrete, they all have their own draw-backs and require specialised tools.
You can buy special anchor bolt holders if you do choose to place the bolts before the slab is poured. The timber needs to be treated to a grade that is suitable for continuous contact with the ground (ask your supplier). I thought it is going to be an almost impossible mission to DIY our own storage shed so we have resorted to under-the-bed boxes, but I guess that fact is going to change. If you’re looking for a budget garden building our Overlap Garden Sheds are perfect for storage and have a rustic look. This action will not remove the moisture from the air but will however stop it from condensing due to its insulating properties. If the area of the paving is troubled with weeds, it may be necessary to treat the excavated sub-grade with a general weedkiller such as Sodium Chlorate, but it is unlikely any weed will be able to penetrate the upper layers. However, bear in mind that adding further water to the prepared mix can affect the cured strength of the finished concrete and may invalidate the strength guarantee of the supplier, leaving the contractor responsible for any remedial work. Long-reach floats can be used on larger areas, and for that perfectly smooth finish, a power float is the tool for the job.
After that, foot traffic can be allowed onto the slab, with care, but it should not be open to heavy foot traffic or slow-moving vehicles until 5 days after pouring. The 100mm thick slab normally has a single sheet of mesh, while 150mm and thicker slabs will have two layers of mesh, "top and bottom", each with at least 50mm of cover.
This trench will mean that the concrete around the edge of the slab, where the walls will sit, is thicker than the concrete in the center. Extra space is always needed especially when things keep getting piled up around the house each day.
Shed Supermarket also offers a Portabase; this is a wooden base suitable to certain wooden sheds. This method will work, however you need to make sure that no water will pool underneath the wooden floor as this may then start the problem again.
These are awkward, heavy machines, available from Hire Centres, but are not recommended for use by DIY'ers. For heavy usage, such as highways, runways, ports or commercial yards, it may be 10 days before the slab is ready to take traffic.
