Retaining Wall Contractor in Coquitlam

Coquitlam's residential areas climb across the hillsides above the Lougheed corridor, and the terrain here creates some of the most demanding retaining wall conditions in the Lower Mainland. Burke Mountain, Westwood Plateau, Eagle Ridge, and Ranch Park are neighbourhoods where lot grades often exceed 30–40%, and where retaining walls are as fundamental to the property as the foundation of the house itself.

We work regularly in Coquitlam on both new retaining wall construction and repair of older walls that are reaching the end of their engineered life. Coquitlam's rapid residential development over the past 30 years means there's a large population of walls built in the 1990s and early 2000s that are now showing their age.

Coquitlam Retaining Wall Conditions

Coquitlam's higher-elevation neighbourhoods (Burke Mountain, Westwood Plateau) typically have shallow soils over bedrock or glacial till, with significant surface water runoff during rain events. Wall drainage in these areas must be sized for high-intensity, short-duration runoff rather than just slow percolation through soil.

Lower Coquitlam, particularly along the Coquitlam River floodplain, has softer alluvial soils that require more conservative footing designs. We assess soil conditions as part of every Coquitlam site assessment.
