Ecobase Fastfit Shed Bases are designed to provide a firm long lasting base to install a garden building on. Each kit comprises a number of strong, heavy-duty grids made from 100% recycled plastics that click together, and a sheet of weed resistant membrane to stop weeds growing under the building. The grids are lightweight and simple to install following the instructions provided - they are lighter and easier to handle than paving flags, less messy and quicker to install than laying a wet-mix concrete slab. Ecobase Fastfit Shed Base kits are suitable for most garden buildings including sheds, workshops, summer houses, log cabins, playhouses, log stores, cycle shelters and bin stores.
