The best and cheapest way to build a shed base

Time and time again we’ve discussed the many options available when it comes to building a shed base. We’ve gone through the pros, the cons, the aesthetically pleasing, the permanent and the portable, but we’ve never given a definitive answer on which product we consider to be best. Today, that changes, and we’ll give you the lowdown on the product we consider to be the best, based on ease of use, price, practicality and customer satisfaction.


Although slabs, concrete and wooden bases all have their merits, they also come with quite a few disadvantages. Plastic shed bases on the other hand have very few disadvantages, it’s just that the majority of people never consider them as an option – to be honest, the majority of people are yet to discover them. Due to being relatively new to the market compared to veterans like slabs and concrete, when you search online for “what’s the best material for a shed base?”, unless you’re looking at a relatively recent article, plastic bases are unlikely to feature. However, there are plenty of reasons that they definitely should.


Plastic shed bases are available in various colours. We sell white, black and green so the base can be as obvious, or as inconspicuous as you like. As it’s advisable that the shed’s base is larger than the floor of the shed, you can even create a decorative boarder using the pavers, filling each with either soil and grass seed, gravel or bark – other fillings can also be used but these are by far the most popular.

Air circulation

The composition and design of our plastic shed base range may seem a little strange at first. Each panel is secular in design with the intention of certain panels being filled to add further support to the shed above. Typically, with other types of shed base, because they’re solid, a layer of air is trapped between the shed base and the bottom of the shed. This can quickly become warm and moist and, if left, could cause a severe damp problem that’ll leave your shed rotting from the base up.

Because a plastic shed base isn’t solid, it solves this problem by allowing a constant air circulation between the shed base and the base of the shed. As a consequence, this keeps the shed dry, prevents damp and therefore considerably lengthens the life of your shed.


The fact that these shed bases are in fact made of plastic rather than wood or concrete means that they’re extremely lightweight and therefore transportable by pretty much anyone. Each panel is easy to lift and carry, wheel in a wheelbarrow and easy to load into the back of a vehicle should your shed location be different to your delivery address.

The fact that they’re lightweight also makes them really quick and simple to install. Each panel features an interlocking mechanism on each side which attaches in seconds to the other panels. Most people can expect to lay around 100m2 of these plastic pavers in just an hour, so there’s no need for building your shed base to take up your entire day.

Environmentally friendly

Made from 100% recycled plastic from right here in the UK, each one of the plastic pavers available on our site has avoided filling Britain’s already overflowing landfill areas, for a further 450 years. Instead, we make good use of the plastic, creating one of the most durable, cost effective and environmentally friendly products on the market.


Providing they’re installed correctly, each of these shed bases has a serviceable life of between 10 and 20 years, because they’re strong, chemical resistant, weather resistant and also UV resistant too. This means that each plastic panel will be just as effective after 10 years as it was the day you originally lay it.


People are often a little dubious about the capabilities of our plastic shed bases, just because they’re plastic. However, they’re stronger than the majority of other bases available and are certainly a whole lot better looking. These base panels can withstand weights of up to 420 tonnes, meaning not only can they take the weight of a shed that’s filled with everything from garden furniture to bikes and barbecues, they can also withstand the weight of a HGV and pretty much anything else you throw at it!

Water retention

Our panels are all SUDs compliant and made to comply with the Flood and Water Management Act 2010; this means that, unlike other shed bases, surface water build-up and risk of flooding is significantly reduced. Not only that, a plastic shed base is unable to retain water which means that there’s no risk of damage to the base or of water collecting and causing damp on the bottom of your new shed.


Over time, it doesn’t matter which shed base you choose rainfall will cause the ground sink somewhat. However, this is much less of an issue with a plastic shed base, let us explain…

The amount of rainfall the UK is subjected to each year means that the ground is constantly trying to dry out. When a shed is placed directly onto grass or soil, as some people like to do, when it rains and ground becomes sodden, the shed (or anything heavy for that matter) will start to sink into the ground. This sinking is rarely even, as very often some areas of ground are considerably stronger, or more compacted, than others. This means that as soon as the shed starts to sink, it becomes uneven and, overtime, is left under immense pressure because of this strain.

The same thing can happen with concrete or slab bases too, because each time it rains, more and more of the hardcore is broken down as the sandier elements of the concrete are washed away (this is the same element that the rain water washes out of soil). Eventually, the same thing happens as with a compacted soil base, albeit it’s a much lengthier process. The point is though, the only way to rectify the impact the rain has had is to have the shed professionally lifted and the base built back up again.

With a plastic shed base on the other hand, although the sandier elements of the ground are still washed away (remember this is considerably reduced if you use our recommended membrane at the time of installation), the interlocking function of the grids provides a constant level base. You should also remember that a plastic base will not be affected by the rain in the same way that wood or compacted soil is, which means your base remains solid all year around.

Customer opinion

As promised, there’s no need to take our word for it, here are just a few things our customers had to say about our bases, if you’d like to see any more just click here.

“Shed base arrived very quickly and was easy to install. I was laying for a 10 x 8 summerhouse and had most of the panels down in half an hour. I then had to spend a bit more time cutting the final ones to size but this was easy to do with a general saw.
Would thoroughly recommend this type of shed base over a concrete or slab base.”

“Put the base together today and very pleased with the result. It’s tough, fits together really well, came with good, clear instructions, well packaged – highly recommended without any reservation.”

“very pleased with shed base, very easy to construct, lightweight to move into place and very sturdy. Easy to make more solid by filling cells with small stones or sand.

order & delivery was very easy and quick.Have already recommended these bases to 2 friends.”
