Keystone Retaining Wall System
The Keystone Retaining Wall System is the structurally sound aesthetically appealing, easy-to-install, and economical solution to replace boulder, timber tie and cast-in place retaining walls. As a gravity wall system, the original Keystone Standard Unit provides the weight and stability to resist applied earth pressures for walls up to six feet high. And it doesn't stop there! Keystone offers a wide variety of products with different sizes, shapes, face textures and colors for superior gravity and reinforced walls that rise in height from one unit to over 50 feet.
The Keystone difference is its outer beauty and inner strength. Keystone's patented, interlocking, fiberglass pin system ensures positive connection between the structural wall unit and the soil reinforcement. The combination of Keystone units, positive pins connections, and soil reinforcing geogrids delivers rock-solid stability and performance. When you are building walls that need to hold literally tons of soil mass, you simply can't hope the geogrid is where it supposed to be. You need to know it's locked in place. Keystone's fiberglass pin connection system gives you that critical assurance.
One look at the face of the Keystone Retaining Wall and you'll see what makes it stand out. Graceful curves. Classic lines. Shadows and textures. Geometric patterns. With so many options, Keystone remains the preferred choice among architects, engineers, developers, and contractors.
