The main difference between to two cast stone product processes is the quantity of water use.
Wet cast is a concrete mixture of aggregate and cement which remains in the mould until cured. This process also offers greater strength where required, in comparison to dry cast stone.
Wet cast stone uses considerably more water to manufacture, which results in close-grained material with a smooth surface. This lends itself to creating intricate details and most closely resembles natural stone. Our wet cast stone is manufactured to BS 6457:1984 and benefits from low water absorption, making it ideal in exposed areas.
Semi dry cast stone is an aggregate and cement mixture which is packed into moulds then removed to cure. As less water is used to produce semi-dry cast stone, the mould that each product is cast in can be used more frequently, as the material can be transferred from the mould almost straight away. This often means that semi-dry cast stone is more economical with shorter lead times. Our semi-dry cast stone is manufactured to BS 6073:1981.
