Sigma Wall

The Cambridge Sigma Wall System is built to the highest standards in height, texture, color and ease of use. Designed from contractor feedback, professional installers asked for a stone that would not hurt their back, a connection system that was simple to use with no pins, a large wall system that matched our Maytrx and Outdoor Living Kits and a wall that looked good in a residential backyard. The Sigma installs as delivered with a 6 degree setback, or by knocking off the front set of “break away” knobs to get “near vertical” alignment.

Mortarless Segmental Retaining Walls installed in North America surpass every country worldwide. Department of Transportations throughout the United States use this engineered wall system in building tall walls along our highway infrastructure instead of poured in place or stone walls.
