Earth Retention
Retaining Walls
Engineered earth retention solutions for residential, commercial, and infrastructure projects. Designed to last.
Retention Solutions for Every Site
Retaining walls are engineered structures that hold back soil and rock on slopes. Coast Geotechnical designs retaining walls for residential, commercial, and infrastructure projects across Western Canada, from small gravity walls to large soldier pile and mechanically stabilized earth (MSE) systems. We coordinate with structural engineers and contractors to deliver practical, cost-effective solutions.
All designs are prepared and sealed by a licensed Professional Engineer in BC, and include the geotechnical recommendations, structural drawings, and specifications required for building permit submission.

How It Works
Site Assessment
We evaluate the site topography, soil conditions, drainage, and surcharge loading to inform wall type selection and design parameters.
Wall Design
Our engineers prepare geotechnical recommendations and coordinate structural wall design, including drawings and specifications ready for permitting.
Construction Support
We provide inspections and engineering review during construction to confirm the wall is built to design intent.
