Keystone Compac Hewnstone combines style, performance and cost-saving versatility into one wall system. It’s favoured by architects, engineers and contractors worldwide for its function in both small and large-scale projects. Using the proven Keystone pin connection system, Keystone Compac® Hewnstone is the perfect solution for gravity walls up to 4 feet in height and large-scale projects over 60’h. Corner and coping units are also available.

Maximum Versatility and Performance Due to:

  • A design that results in decreased unit weight, effectively reducing shipping costs while maintaining structural integrity.
  • A design that allows for various positive connections with reinforcement to build engineered walls over 60 feet (18.2m) tall. 
  • Increased vertical drainage through face units. 

Easier Installation Due to:

  • A block shape that allows for tight radius curves and vertical core alignment.
  • A shorter tail design that allows for easier handling in the field.
  • A triangular shaped pin receiving hole that allows for installer-friendly construction adjustments.
  • Vertical or battered setback construction options.
