Repair cracks

Repair of cracks in concrete

Cracks that are not repaired can grow if they are not repaired as soon as possible.

Repair of cracks in your foundation even during water infiltration!

Types of crack repair:

Epoxy application on the crack
Injection at high pressure or low pressure into the crack using polyurethane or epoxy.
Injection of cementitious grout into the crack

Crack repair step:

Drill holes in the crack every 4 to 6 inches to inject the appropriate product as efficiently as possible
Clean holes and cracks
Installation of injectors in the crack
Inject the polyurethane at a pressure of 3000 lbs to 10000 lbs in order to seal the crack

Our company is at the forefront of technology around the world, we inject cracks under pressure using a specialized injector.

We inject flexible polyurethane to ensure our repair (injection) if the ground is in motion.

All our products are approved by the MTQ hydro Quebec and the airports for a satisfaction ensure.

Cracks can be sealed even during infiltration.

Epoxy injection can also be done if necessary when the crack is too large we can also install inking units on the crack to stabilize it.

Crack in a solage due to ground movement

Movement of the footing during freeze/thaw can cause cracks in the foundation. If you are building your home early in the spring or late in the fall, you should check that the ground is not frozen before starting any work. If the ground is frozen during construction, it could cause voids under your foundation or concrete slab. If you have a void under your foundation footing, we can inject high-density polyurethane specially designed for this type of work. You will thus avoid paying to have cracks repaired in addition to stabilizing the foundation.

Which anchor to choose for a concrete crack?

The photo shows the size of the anchors used here. The corner of the foundation was too cracked to only repair the crack without anchoring. In this case, the cause of the cracking is the frost wall that was not done. The foundation rests only on a foundation footing. When the foundation is exposed as in this case, a frost wall of at least 4 feet is necessary to counter the effect of freeze/thaw. After repairing the cracks and installing anchors, we add a superior quality membrane (cm-100) to better protect the foundation. The membrane is installed only on the part of the foundation that will be backfilled.
