About Our Shed Bases

Our eco-friendly shed bases are manufactured here in the UK from 100% recycled plastic. Owing to its unique formulation, our flexible but incredibly strong blend of recycled plastic makes every foundation both weather and UV resistant. Its resilience against the sun, rain and heat means that your shed base will not rot away or break down over time which can be the case with more traditional foundations such as wood or concrete. With a specially designed cell structure our bases have a very large load baring capacity as well as being fully permeable which means that rain and other liquids will drain naturally away from your garden building, reducing the likelihood of surface water being absorbed and potentially rotting your shed.
