Plan the Complete Sigma Wall

A professional wall installation requires more than selecting the face unit.

Choose the Wall System

Select Sigma 6 or Sigma 8 according to the scale, appearance and structural requirements of the project.

Plan Corners & Caps

Identify corners, exposed wall ends, columns and cap requirements before calculating final quantities.

Coordinate the Hardscape

Compare Sigma colors with surrounding Cambridge pavingstones, steps and other outdoor-living materials.

Engineered Retaining Wall Note

Retaining-wall design, base preparation, drainage, reinforcement and installation requirements depend on wall height, loading and site conditions. Engineered applications should follow current Cambridge technical specifications, applicable building requirements and the recommendations of the appropriate design professional.
