These paver moulds are used to cast stones that are generally smaller paver bricks. They are more suited to High Load areas. The concrete should be mixed to a higher strength than that required for low load areas, eg walkways and patios. The double cobble paver and sandstone cobble is ideal for this application. Special care must be taken in the preparation of the substrate prior to laying as the completed driveway can only be as good as the material the stones have been founded on.
Always line your moulds with Release Agent prior to casting. This prevents the concrete from sticking to your paving moulds.
