When injecting cracks is the best solution

Injection crack repair means identifying the angle of the crack, from the exterior, then filling up and patching neatly, so the surface appears barely untouched.

Repairing foundation cracks through polyurethane injections

The nature of concrete means possible shifts and cracks over time. In certain cases, cracking isn’t serious and doesn’t pose a threat to the structure. You still want to stay on the safe side and take preventive measures. It’s important to remain vigilant and carefully examine cracks you detect. Better to fully assess the situation and avoid costly problems later on.

Cracks can be active or passive, and its essential to identify what you’re dealing with, prior to beginning a repair job. Cracks that stem from natural movement, bad initial compacting or shifting of the soil around the foundation, will normally stabilize after a year. On the other hand, cracks caused by frozen soil that’s expanded, by landslides, or by poor compression of the initial product, can remain active and worsen over time. We have to first stabilize the crack, before attempting repair. For severe or deeper cracks, we install metal support plaques to consolidate and stabilize, protecting the structure from the ravages of potential movement in the building.

Polyurethane injections via your basement interior

Polyurethane is a resine that’s designed to seal cracks to avoid leakage. This resine also works as an accelerator that reacts when in contact with water, forming closed microscopic cavities with excellent grip, and a long lasting adaptability. This flexible product adapts to the flow of concretes’ natural shrinking or expansion, that’s due to thermal shifts. Polyurethane injected into cracks will expand to 20 times its volume, and completely seal the required space.
