ShellStone is a product style in the SeaStone Collection series.  ShellStone is a cementitious stone containing a proprietary admixture using natural fossil shell and other aggregates which vary from piece to piece designed to replicate the appearance of natural stone. An enhanced manufacturing process applies tons of pressure to each unit, fusing the aggregates and fossils together which simulates a natural occurrence. This unique process ensures a more durable product with high compression strength and low water absorption qualities thus providing an alternative to the use of natural stone. The ShellStone style reveals the beauty of  natural fossil shells  through a high quality, machine finished surface replicating coral or coquina.
