3 Best Shed Bases of 2025

Eco Deck is a company based in the midlands, and their strong Garden Shed Base is made from UV-stabilised recycled polyethylene. In testing they claim that even unfilled it can withstand over 150 tonnes of force, and in practise it seems both strong and durable.

This particular option measures 2.4 x 1.8 m (8 x 6 ft), although other sizes are available, and is suitable for acting as the foundation for similarly sized sheds. It can either be used for sheds of the same size, which are relatively standard as sheds go, or smaller models which will leave a parameter of base visible around the shed.

It creates a flat, level foundation which is unnoticeable within the shed itself, creating a way for water drainage and ventilation to benefit the structure.

Overall, assembly is relatively easy, and it comes in separate squares that need to need to be clipped together. Clips come included to make this possible, as the pieces aren’t interlocking, but many people choose to use heavy-duty cable ties instead to make the process easier. One of the most challenging part of the process can be levelling the ground in the first place before setting the grids in place.

A sheet of weed membrane is also provided, to stop weeds from growing up under the base. Although it’s not 100% necessary to use gravel to fill in the grids, and some people choose not to, the weed membrane helps keep the base appearance tidy either way.

Not only is this a useful product for sheds, but it can also be used to make paths that are suitable for wheelchairs, pushchairs, mobility scooters and even cars, so it’s one of the best shed bases in terms of versatility and functionality, with a wealth of uses around the garden.

Overall, this is an easy option that is a lot quicker, and more environmentally-friendly, than using concrete. The grid is sufficiently strong without being filled that it doesn’t have to be used with gravel, but both options are available.

This CrazyGadget Garden Shed Base gains a spot on this list as one of the best shed bases because it is relatively inexpensive but offers good value for money. 20 plastic grids come included, which connect together to make a secure base of 5 m²; this is a larger coverage area than the other products on this page, yet the price stays low.

The overall quality may not quite be as high as with the Eco Deck base, and you don’t get peace of mind of buying a product made from recycled materials, but it still works well as both a shed base or pathway.

It seems that the strength of these grids is greatly improved by packing them with sand, gravel or soil, and when installed correctly they can form a strong foundation for both wooden and plastic sheds.

Installation is relatively straight forward, though the ground needs to be levelled first which can be the most time-consuming part. Care needs to be taken not to force the tabs when fitting the grids together as well, as they can be prone to breaking.

The main disadvantage of this shed base is that it does not come with weed membrane, so you’ll need to find one of the appropriate size to purchase separately, in order to prevent weeds from growing up through the grid.

Even so, it still remains a good value purchase that will create a good foundation for the shed, you just need to make sure that you follow the instructions to make sure it’s as strong as possible.

If you don’t want to worry about using gravel to help drainage, this Hawklok Garden Shed Base is self-ventilating and free draining. It’s not necessary to use any gravel, and it’s therefore likely to save both money and time.

Overall, this is a simple product that works effectively for its intended function. Although not the cheapest, it comes with a weed membrane included and is straight forward to clip together.

Given that it isn’t necessary to fill with gravel, it’s one of the easiest shed bases to move and reposition, making it possible to change the location of the shed in barely any time.

Putting the grids together can take as little as 10 minutes, and will be easily completed in under 30. Like most shed bases, it needs to be installed over level ground and this is the part of installation that can take the most time.

The grids are made from 100% recycled plastic, similarly to the Eco Deck base, making this a relatively eco-friendly option.

All in all, it’s an easy shed base to install, taking very little time to lay out the membrane and click the grid pieces together. It’s a simple, eco-friendly, cost-effective alternative to laying a concrete or wooden base, and one of the best shed bases for keeping the shed ventilated and free of damp without having to use gravel.
