Solution — "A crack in my concrete is actively leaking"
Polyurethane & Epoxy Crack Injection
A crack in concrete that is actively leaking is a problem that needs to be fixed quickly. The water that is coming through the crack is carrying the concrete, and the crack is getting wider. The water is also the structure, and the longer the crack is left, the more the structure is damaged. The first step is to understand the crack. We need to know the width of the crack, the depth of the crack, and the cause of the crack. The crack can be caused by the movement of the structure, by the settlement, by the thermal, or by the overloading. The cause of the crack determines the repair. For a crack that is actively leaking, we use a polyurethane injection. The polyurethane is injected into the crack under pressure, and it expands to fill the crack and the water. The polyurethane is a water-reactive material that swells in the presence of water, so it is the ideal material for a crack that is leaking. The injection is done from the surface, and the crack is sealed from the inside. For a crack that is not leaking, but is a structural crack, we use an epoxy injection. The epoxy is injected into the crack under pressure, and it bonds the two faces of the crack together. The epoxy is a structural material that restores the strength of the concrete, and it is the ideal solution for a crack that is structural. The injection is done with a series of ports that are placed along the crack. The ports are sealed to the surface, and the resin is injected through the ports, starting at the lowest port and working up. The resin fills the crack, and the ports are removed when the resin has cured. We also look at the cause of the crack. If the crack is caused by the movement of the structure, the movement has to be addressed, or the crack will open again. We look at the structure, the foundation, and the loading, and we recommend the repair of the cause as well as the crack. The result is a crack that is sealed, a crack that is watertight, and a crack that is structurally sound. We document the injection, we provide the specification, and we stand behind the work. The first thing we do is look at the crack. The crack is the opening that is the concrete, and the crack is the opening that is the water. We look at the crack, the width, and the depth, and we find the cause of the problem. The width of the crack is the first thing we check. The width is the opening that is the crack, and the width is the opening that is the water. We check the width, the depth, and the movement, and we find the path of the water. The depth of the crack is the next thing we check. The depth is the depth that is the crack, and the depth is the depth that is the water. We check the depth, the reinforcement, and the structure, and we find the path of the water. The result is a crack that is sealed, a crack that is protected, and a crack that is the water. We find the path of the water, and we stop the water. The first thing we do is look at the crack. The crack is the opening that is the concrete, and the crack is the opening that is the water.

Our approach
- On-site inspection to confirm the source and extent of water ingress
- Substrate testing where relevant (moisture content, adhesion, cracking)
- Written specification naming the system, prep required, and application method
- Certified application following manufacturer specification
- Documented sign-off and warranty information on completion
