The CornerStone® Difference.. The Installation Advantage!

Ideal for residential landscaping, CornerStone® retaining walls offer the perfect combination of structural strength and aesthetic beauty. They are also much easier to install thanks to our patented SecureLug connecting system, which eliminates the need for expensive pins or clips, saving both time and money on the installation.

CornerStone® units feature a vertical hollow core that combines durable, precast concrete with ease of installation. When stacked and filled with aggregate, CornerStone® units interlock, providing high shear resistance and excellent connection strength to geosynthetics reinforcement, if required. The SecureLug connection system also provides for maximum layout creativity and easier installation when building curves, corners or angles. For value, beauty,  durability and ease of construction, your best choice is CornerStone®.

Engineered For Strength

CornerStone® has been thoroughly tested for connection and strength in accordance with the design methodology promoted by the National Concrete Masonry Association (NCMA). Its unique SecureLug connection system, when combined with gravel infill and geosynthetic reinforcement creates a strong, long lasting retaining wall. CornerStone’s durable, high shear strength concrete SecureLug fits into the lower unit’s hollow core, allowing significant lateral movement without losing the connection interlock. CornerStone® walls flex with seismic pressures and resist weathering. The hollow core of each unit provides excellent drainage, reducing water pressure behind the wall.

CornerStone's Hollow Core Advantage

• Lighter weight for shipping and handling.
• Increased vertical drainage through the units.
• Allows for gravel interlock across unit interfaces.
• Improves connection between units and geosynthetic.
• Improves unit-to-unit friction shear resistance.

Designed For Beauty

The CornerStone® system has a unit designed to accommodate nearly every type of retaining wall application. The units typically have a random split face that resembles weathered rock. Unit shape and size are balanced to provide a natural profile that complements virtually any design or style of construction.

The CornerStone® SecureLug Connection System

CornerStone’s SecureLug, when combined with gravel infill, provides very high unit to unit shear resistance and excellent unit connection strength to geosynthetics. The absence of expensive pins or clips promotes layout flexibility, while saving time and expense during installation.
