Keystone Compac®

The Keystone Compac® series, brought to you by Keystone Hardscapes and distributed by AR Stoneworks & Outdoor Living, stands as a testament to unmatched aesthetic appeal and functional brilliance. Acclaimed by specifiers globally, this unit not only brings visual delight but is also revered for its easy handling, courtesy of its lightweight design and shorter tail. The hallmark of this series is its trusted pin connection system, which sets the Keystone Compac® apart in the realm of retaining walls.


  • Elegant Appearance: A straight split face design in each unit showcases the vivid color, enhancing the overall visual appeal.
  • Innovative Installation: Uses 1/2in diameter, pultruded fiberglass pins, enabling versatile placements with a remarkable shear strength of 6,400 psi. Keystone pins bolster the unit’s interaction with geosynthetic textiles.
  • Optimized Design: Superposed webs quicken the core-filling process, while its leading weight and ergonomic grips ensure safe and straightforward handling.
  • Optimal Space Utilization: Its low batter design ensures maximum usage of the available site area.
  • Durable Composition: Crafted from high-grade concrete infused with iron oxide pigments, it promises resistance against fading due to UV exposure and meets the standards of ASTM C1372.
