Keystone compac units are made of high-strength, low absorption concrete for long lasting structures. Featuring an open core design and interconnected using the secure fiberglass pin connection system that is trusted by engineers and contractors around the world, the Keystone Compac blocks have the stability of a large mass but are easier to handle, lighter to place and quicker to install than boulders, crib structures or thin-shelled panel structures.

Due to the fiberglass pins, movement between blocks is restricted making alignment during installation easier and faster. It is available in a split finish which provides a natural rock surface look to the wall.
