Foundation Repair Vancouver

We use the materials and methods that actually last in Metro Vancouver's specific conditions — expansive clay soils, high water tables, acidic groundwater, and annual rainfall that tops 1,150 mm in parts of the Lower Mainland.

For crack injection, we use low-viscosity epoxy (Shore A 65 rigid cure) for structural restoration and hydrophilic polyurethane foam for active wet cracks where movement is still occurring. Both systems comply with ACI 224.1R crack repair guidelines. Injection ports are spaced to the crack depth-to-width ratio, and we verify penetration with a tracer before patching the surface.

Helical piers are hot-dipped galvanized steel meeting ASTM A153 standards, rated to 150 kN tension and compression. We use a hydraulic torque head on a mini-excavator or a tracked Bobcat for access-restricted lots. Installation torque is continuously monitored and logged; accepted when empirical torque correlates to the designed capacity for a minimum of three consecutive readings.

Exterior waterproofing membranes are rubberized asphalt modified bitumen (1.5 mm minimum DFT) applied to a prepared, primed concrete surface. We install 10 mm dimple mat drainage board from footing to grade line with filter fabric to prevent soil migration — this prevents the membrane from loading under hydraulic pressure, which is the most common cause of premature membrane failure in BC.

Carbon fibre straps used for bowing wall repair are unidirectional woven carbon fibre with a minimum tensile strength of 620 MPa, bonded with two-component structural epoxy. We follow ICRI Technical Guideline 320.5R for surface prep — all concrete is mechanically abraded to CSP 3 before bonding. Wall anchors where installed are tested to 35 kN before final torque.

All structural work is engineered to BC Building Code (BCBC 2024) requirements. Where a Professional Engineer of Record is required by the authority having jurisdiction, we engage a local structural PE and incorporate their stamped drawings into the permit package. Our crews hold WSBC safety training and our job supervisors are certified in confined space entry for crawl space and sub-slab work.
