Foundation Crack Injection Pickering

We map cracks, record widths and leakage, review movement and load history, sound the surrounding concrete, and identify whether external water pressure or failed joints must also be addressed. After cure, ports and surface seals are removed or finished as specified. We inspect continuity, address voids, and complete water testing or monitoring where the project requires performance confirmation.

The governing document set is the 2024 Ontario Building Code, CSA A23.3 where structural design is involved, CSA A23.1 concrete requirements, engineer-issued repair details, and manufacturer installation limits for the selected Canadian-market system. Material selection considers viscosity, reaction time, moisture tolerance, elongation, bond strength, expansion, temperature, crack width, and whether the repair is structural or water-control work.

The price responds to crack length and width, access, active leakage, wall thickness, resin type, drilling pattern, surface preparation, working height, water control, finish removal, and testing requirements. Wrong resin chemistry causes poor bond, brittle failure, uncontrolled foaming, or incomplete penetration. We match the product properties to moisture, width, temperature, and movement.

The controlling schedule factors are moisture and temperature, access preparation, leakage control, material reaction time, crack complexity, required monitoring, and coordination with operations on the opposite side of the wall. After cure, ports and surface seals are removed or finished as specified. We inspect continuity, address voids, and complete water testing or monitoring where the project requires performance confirmation.

Yes. Injection equipment has a small footprint. We isolate the repair zone, protect nearby equipment and finishes, control resin discharge, and phase work around plant or tenant operations. Wrong resin chemistry causes poor bond, brittle failure, uncontrolled foaming, or incomplete penetration. We match the product properties to moisture, width, temperature, and movement.

We record crack mapping, material batch, port spacing, injection sequence, pressure and resin take, observed communication between ports, completed surface finish, and specified water or monitoring tests. Material selection considers viscosity, reaction time, moisture tolerance, elongation, bond strength, expansion, temperature, crack width, and whether the repair is structural or water-control work.

Provide crack locations and lengths, photographs, drawings, wall thickness, access on both faces, leakage conditions, prior repair history, structural reports, finish requirements, and operating constraints. After cure, ports and surface seals are removed or finished as specified. We inspect continuity, address voids, and complete water testing or monitoring where the project requires performance confirmation.

Epoxy is normally considered for dry, stable cracks that require structural bonding. Polyurethane is normally considered for active or potentially wet leakage paths because suitable formulations can react with water and tolerate limited movement. Crack activity, width, wall thickness, temperature, access, and the engineer's repair objective control the final selection.

Often it can, provided the crack can be traced, the injection path is accessible, and uncontrolled resin discharge will not damage the exterior assembly or adjacent spaces. Exterior excavation may still be needed when the membrane, drainage, wall surface, or multiple connected defects require direct repair.
