Technical Standards and Best Practices

The Concrete Masonry and Hardscapes Association establishes the technical standards for segmental retaining walls and interlocking pavement systems. Following CMHA guidelines ensures installations meet structural integrity requirements and deliver long-term performance.

Understanding these technical standards is crucial for delivering hardscaping solutions that stand the test of time. Proper installation techniques, appropriate material selection, and adherence to engineering specifications distinguish professional work from amateur efforts.

We look for these standards at every phase of the projects we review. The details many people overlook decide the outcome: proper compaction, adequate drainage, appropriate base preparation and precise installation.
