The Keystone Compac Hewnstone wall system blends elegance, performance, and cost-effective adaptability. It is popular among architects, engineers, and contractors worldwide because of its versatility in both small and large-scale projects. Using the tried-and-true Keystone pin connection method, Keystone Compac® Hewnstone is ideal for gravity walls up to 4 feet tall and large-scale projects exceeding 60’h. Corner and cope units are also available.

Maximum Versatility and Performance Due to:

• A design that reduces unit weight, hence lowering transportation costs while retaining structural integrity.
• A design that provides for a variety of positive connections with reinforcement for building engineered walls taller than 60 feet (18.2m). 
• Face units provide more vertical drainage. 

Easier Installation Due to:

• A block form that accommodates tight radius curves and vertical core alignment.
• A shorter tail design allows for simpler handling in the field.
• A triangular-shaped pin receiving hole provides for easy installation modifications.
• Construction choices include vertical and battered setbacks.
