Keystone Retaining Walls sets the worldwide standard for excellence and innovation in the hardscape industry. As the first U.S. segmental retaining wall enterprise, Keystone has cultivated a portfolio that includes not only the best structural concrete retaining wall systems, but versatile and stylish landscape and do-it-yourself products, such as patio stones, edgers and outdoor living element designs. We offer the highest-quality site solutions for government, commercial/ industrial, recreational, public works and residential applications.
The Keystone® Verazzo Stone offers a handsome and rugged good look combined with unmatched strength and stability. Each Verazzo Stone unit is finished on two sides and allows the look of a random-pattern system without requiring a mixed pallet or multiple pieces. The angling of both sides results in different face lengths that allow for tight fitting straight-line walls and radii at curves.
We are now offering our Verazzo in an antique finish. The block has the same rugged features of Verazzo with an ‘old style’ finish for that rustic look available in our two blends, NE Fieldstone and Wachusett Blend.
The Keystone® Victorian Stone products provide improved design features that contractors and specifiers are sure to benefit from. Larger open core space in the center of the unit ensures sufficient infill placement, reduces overall weight for ease of handling, and enhances connection strength with geogrids.
The Keystone® Standard Compac Series products provide improved design features that contractors and specifiers are sure to benefit from. Larger open core space in the center of the unit ensures sufficient infill placement, reduces overall weight for ease of handling, and enhances connection strength with geogrids.
Keystone interlocking pin system maximizes design options, improves the installation process and increases the structural integrity of retaining walls. Allowing for a near vertical or setback installation, Keystone interlocking pins not only save time by taking the question out of proper block placement, they also improve interaction with geosynthetic textiles. Keystone pins are virtually weatherproof, helping the wall to withstand weather challenges.
Designed for lifting and placing Keystone Compac and Keystone Standard units, the Keystone KeyLifter allows two people to easily carry and set a unit by sharing its weight between them. The unique, upward handle design permits the unit to be placed into the wall without injury to hands or fingers. Once the unit is set in place, the KeyLifters can be easily removed from the pin holes for use on the next unit.
