Fernhill Stone products are lightweight and produced in preselected sizes and shapes. No additional foundation or wall support is required. Installation is quick and easy, and costs far less than a full thickness natural stone wall. They are cast in moulds, using a unique process that replicates existing colours and textures with meticulous detail. Each colour and texture has its own blend of ingredients: including portland cement, lightweight aggregates and iron oxide pigments, producing the look and feel of natural stone.
