Eco Deck Garden Shed Base Grid 8 x 6 Feet Review
This Eco Deck Garden Shed Base comes with plastic grids and a membrane sheet. This kit comes with all you need to construct a base for a shed of 8 x 6 feet and additional sizes are available. The grid can also be used to make paths that are suitable for wheelchairs, pushchairs, mobility scooters and even cars.
This plastic shed base is made in the UK from recycled materials which makes it a more environmentally conscious choice than concrete.
I found this plastic shed base relatively easy to install. Of course, the area must first be made level, but after that, you simply put down the membrane and connect together the plastic grids. The kit is supplied with connectors, but I found these a little flimsy and fiddly. Instead, I used heavy duty cable ties to connect the grids and this worked a treat. The grids can also be filled in with sand or pea gravel for extra stability, but the kit provides a good sturdy base, with plenty of drainage and ventilation even without infilling.
This kit makes it easy to construct a sturdy base for your shed without the need for major excavation or concrete pouring. This plastic shed base will also be longer lasting than a wooden base and it is definitely easier to construct. In my opinion it’s the best shed base on the market!

The plastic shed base kit does not come with a membrane, so it is advisable to buy this separately to prevent weeds from growing up through the grid. The grids are very sturdy and strong as they are designed for use in heavy-duty situations such as car parks. They are easy to connect together and create a base in very little time and without a huge amount of effort.

Shed Base Buying Guide
A firm, level base is the essential starting point for any shed or garden building. The best base for a shed will make the construction of the shed easier and ensure that all parts line up and doors open smoothly. The best shed base will also extend the life of your shed by protecting it from damp and subsidence. Having invested several hundred pounds in a new shed you will want it to last as long as possible so don’t skimp on preparing a base.
If you do not create the best base for a shed, you may find that soil movement means you shed does not stay level. This will cause the building to warp and doors and windows will become distorted and fail to open and close properly. In addition, if your wooden or metal shed is in direct contact with the earth, water will cause damage. Wooden structures soon begin to rot when in constant contact with damp earth and metal structures will likely succumb to rust very quickly.
In addition, some sheds do not come with a floor and so in these cases, the best base for a shed will be required to anchor it to.
Traditionally, sheds have been constructed on a base made of concrete poured over a sub-base. Alternative options are to lay a paved area or build a wooden frame. However, all these options take considerable time, labour and money.
An alternative to this time consuming and heavy work is to lay a plastic shed base. These come in the form of interlocking plastic grids that clip together to provide a secure, stable base for your shed as well as providing drainage, ventilation and removing the shed from contact with the ground. An interlocking plastic shed base is effective, low cost and easy to install. Most of these bases are made from recycled plastic making them an environmentally sound option, too. A plastic shed base can be laid on grass, or a bed of sand or pea shingle, eliminating the need for expensive excavation and concrete pouring or constructing a wooden base.
A plastic shed base is an excellent fuss-free, low-cost option for creating a firm foundation for your shed or other garden building. Whether your shed is wood, plastic or metal, a plastic base provides an ideal support.
When choosing a plastic shed base make sure you purchase an item that is designed for the job. Plastic decking tiles and other alternatives will not provide the support that a shed needs in order for it to remain stable and square.
If possible, choose a shed base made from recycled plastic to help do your bit for the planet.
Check the measurements of your shed and allow a little extra when choosing the base to ensure proper drainage and ventilation. If your chosen kit does not provide a weed proof membrane, then you will need to buy this separately. If weeds and grass grow under the shed this makes the area damp which can ultimately cause rotting or rusting of your shed.
What materials and tools will I need to lay a plastic shed base on an area of soil?
In addition to the plastic base of your choice and a weed proof membrane, you will need some basic digging tools for levelling the area. You will also need a tape measure, pegs and string to mark out the area and a long spirit level to check you have created a level area to install your base.
You may also want to buy some pea shingle to fill in the grids although this is not usually necessary if you are using them for a shed base.
How should I lay a plastic shed base?
You should begin by measuring the site, making sure it is square, then hammering pegs into each corner. Attach string to the pegs to mark out the whole area. If you need to remove turf do this with a spade of turf cutter. Once you have marked out the site check that it is level and dig out any bumps until you have created a square, level site for your shed base.
Next lay the plastic membrane smoothly across the area.
You are now ready to install the base which is usually simply a matter of clicking it together with connecting pins, though you can also use heavy duty cable ties if you prefer. Once the base is finished you can trim away any excess membrane.
For extra stability, you can infill the plastic grids with builder’s sand or pea shingle.
I want to install a plastic shed base, but I think they look unsightly. How can I camouflage the black plastic and make it look more attractive?
You can dig out an area before installing the plastic base, so the grids will be hidden underground. If the base is slightly larger than the shed – as ideally it should be – simply fill in and cover the visible grids with pea shingle.
Alternatively, you can cover the edges of the grids with some wooden trim and then infill the grids with pea shingle.
