Ecobase Fastfit Garden Building Base kits are designed to provide a firm long lasting base on which to install a garden building. Each kit comprises a number of strong, heavy-duty plastic grids that click together, and a sheet of weed resistant membrane to stop weeds growing up under 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. Ecobase Fastfit Garden Building Base kits are suitable for most timber framed garden buildings including sheds, summer houses, log cabins, log stores, cycle shelters, wheelie bin stores, and workshops.
