Foundation Crack Repair with Polyurethane

For active or significant foundation cracks, our team uses polyurethane gel.
This material expands within the crack and then hardens, reinforcing the concrete at that location. It remains effective and watertight even when moisture is present in the crack.
Polyurethane can be injected either from the interior of your home or business, or from the exterior (following excavation).
Exterior repair is more beneficial, as it allows us to apply a DELTA-MS polyethylene membrane over the entire foundation surface to prevent water infiltration.
Epoxy can be used to seal foundation cracks in multi-story or very heavy buildings, as this sealing gel does not expand as much as polyurethane and will not damage the concrete.

Why Do Foundation Cracks Form?

Foundation cracks can develop due to freeze-thaw cycles, which cause the soil to expand and contract. Water pressure also weighs heavily on the concrete and makes it brittle.

If your foundation is not covered with a waterproof membrane, water can infiltrate and gradually enlarge the cracks.

Soil settling can also damage the concrete by reducing its load-bearing capacity and destabilizing the foundation. This may result in structural distortions, such as doors that no longer close properly.

Tree roots can also grow along foundation walls and create cracks.

Passive and Active Foundation Cracks

Active foundation cracks are longer and wider than passive cracks, which stop expanding after one year. It is essential to seal active cracks, as they can cause serious damage to your concrete.

Water can seep into your basement and lead to mold, mildew, humidity, and respiratory issues. It is important to act quickly to reinforce your concrete and prevent more costly damage.

Passive cracks should also be sealed, as they still weaken the concrete even if they are less harmful.
