The Swift Foundations Ecobase Fastfit Shed Base kit is designed to provide a firm long-lasting base to install a garden shed. Each kit comprises several strong, heavy-duty plastic grids with connectors that click together, and a sheet of weed-resistant membrane to stop weeds from growing into the floor. The kit is lightweight and simple to install following the instructions provided. It is a lot lighter and easier to handle than paving flags and less messy and much quicker than laying a wet-mix concrete slab. The shed base kit is suitable for most timber-framed garden buildings including sheds, summer houses, log cabins, log stores, cycle shelters, wheelie bin stores, and workshops. Size: 9 x 6ft.
