Avoid the hassle or mess of laying slabs or concrete with our ProBASE 8x7 plastic shed base kit, when preparing a base for your new shed. It is very quick to install as its interlocking design makes it easy to put together and, though lightweight, it will provide a very strong and durable base for your shed. Made from 100% recycled plastic, this shed base is eco-friendly. Also, you can reuse the base if you decide to reposition your shed. The base allows for ventilation and drainage under the shed, helping to keep the shed floor dry. To install the base, you simply interlock the square grids together and lay onto a firm, level area of ground. We recommend using 15kg of 10m pea gravel per square (gravel not included). Each square is 500 x 500 x 40mm. This pack contains 25 squares. For your convenience, a heavy-duty, commercially-graded membrane is also included.
