Leak Sealing & Structural Repair

Concrete Crack Injection Vancouver

Polyurethane injection for water ingress and epoxy injection for suitable structural cracks in parkades, foundations and commercial structures.

Waterproofing Resin and Structural Epoxy Are Not the Same

The correct injection material depends on moisture, movement, crack width, access and the repair objective. Flexible polyurethane is typically used to control active water ingress. Rigid structural epoxy may be specified for suitable dry, stable cracks requiring bond restoration.

Injection Solutions

Injection should follow an assessment of the crack, water source, structural condition and surrounding joints or penetrations.

01 / Flexible

Polyurethane Injection

Water-reactive resin used to reduce or stop leakage through suitable cracks, joints and voids in below-grade concrete.

02 / Structural

Epoxy Injection

Low-viscosity rigid resin for suitable dry, stable cracks when restoring concrete continuity is required or specified.

03 / Supporting

Crack & Joint Detailing

Surface sealing, routing, flexible sealants, patching and waterproofing details used where injection alone is not the complete solution.

Controlled repair procedure

Our Injection Process

01

Assess

Review moisture, movement, access, crack pattern and repair objective.

02

Prepare

Clean the surface and establish packer or injection-port locations.

03

Inject

Introduce the selected resin under controlled pressure and sequence.

04

Finish

Remove ports, patch holes, clean and document the treated area.

Real Miyagi work

Access, Inject and Finish

Good injection work depends on correct port placement, pressure control and understanding how water moves through the structure.

Common questions

Before You Request a Quote

Should my crack use polyurethane or epoxy?

Polyurethane is generally selected for suitable active water leaks because it remains flexible. Structural epoxy is rigid and may be specified for suitable dry, stable cracks. The crack must be assessed before choosing.

Can crack injection permanently stop every leak?

Injection treats the selected crack or leakage path. Water may move to connected cracks, joints or penetrations, particularly under continuing hydrostatic pressure, so additional work can sometimes be required.

Can you inject from one side of the wall?

Often, yes. Drilled injection packers can provide access from one side, depending on wall thickness, reinforcement, crack configuration and site conditions.

Does a structural crack need an engineer?

Cracks involving movement, displacement or structural concerns should be reviewed by a qualified engineer. Structural epoxy work should follow the engineer’s repair requirements.

What does crack injection cost?

Pricing depends on crack length, access, wall thickness, water pressure, material, drilling requirements and site conditions. Photos help us provide the right starting point.
