These heavy duty pavers are capable of supporting 150 tonnes per square metre. Each paver is 500mm x 500mm and 40mm thick. Integral pegs on the underside help to level the pavers more easily in soil or sand or shingle. First the ground is levelled and then the pavers are laid directly on the soil. Weed control membranes are not required below a timber floor. If the base is oversize the edges can be backfilled with sand or shingle although this is not essential. Where space permits the base is normally laid full size but if required in a tight location the pavers are easily cut to size with no loss of structural integrity. The base can be up to 1" or 25mm smaller than your building. Fast delivery within 3-5 days ensures that you can start work quickly.
