A perimeter base features a single row of pavers laid around the perimeter of the greenhouse with soil inside. The kit includes weed control membrane which is laid below the pavers. First the ground is levelled and then the membrane is laid directly on the soil. The pavers are laid on the membrane. Each paver features multiple locking clips which are connected within seconds for greater rigidity. The pavers can be backfilled with shingle or left unfilled. Where space permits the base is normally laid full size but if required in a tight location the pavers can be easily cut to size without loss of structural integrity. Each paver is 40mm thick. The paver size is 500mm x 500mm so the inside area is 1000mm smaller than the external size.
