Spot a crack in your foundation?

The first step to repairing a foundation crack is to identify what type of crack it is. There are 3 common types that impact Ottawa foundations.

1) Dry Non-Structural Crack

2) Wet Non-Structural Crack

3) Structural Foundation Cracks

1) Non-Structural Foundation Crack

A non-structural foundation crack is one that does not pose a threat to the structure of the home, and typically only results in leaks during rain storms or when snow is melting. Despite the lack of structural threat in this case, water seeping into your basement is still a serious matter that requires attention.

Water leaking into your home can ruin your belongings, walls and floors, and contribute to the growth of mold. Left unattended, these types of cracks may also get worse. If you don’t act fast to address a crack in your basement, no matter how insignificant it may seem, it’s only a matter of time before you find that water has entered your home.

Renco Tip: Concreate basement walls can have small cosmetic cracks due to the natural curing process. If your crack is between 1 to 2mm and runs vertical or diagonal it may be non-structural.

2) Wet Non-Structural Foundation Crack

This type of crack is the result of foundation shrinkage due to water evaporating from the concrete. It would typically happen within the first month after a foundation is poured. The wetter the concrete mix is initially, the more shrinkage will happen, increasing the likelihood of cracks forming. The natural setting of the concrete can also lead to cracks.

For foundation cracks that are wet and actively leaking, we normally use urethane as a sealant material. It’s a flexible substance that is easy to inject into the crack, and expands to fill the cavity when it comes into contact with water.

Renco Tip: If you spot water or moisture coming from a crack the faster you act the better. Ottawa’s quickly changing weather patterns can cause the crack to grow or lead to more water issues.

3) Structural Foundation Crack

These types of cracks are extremely serious as they pose a risk to the structural integrity of your home. Sure sign of a structural deficiency are horizontal cracks, and cracks wider than a 1/4 inch. Structural foundation cracks are normally the result of movement, whether it’s caused by temperature changes, soil pressure or soil shrinkage.

In this case, epoxy is the material of choice for repairing the crack. Because the crack was initially caused by stress resulting from movement which can continue, epoxy alone is not generally enough to ensure the repair of the crack. Further reinforcement, in the form of carbon fiber countersunk staples or straps, is often necessary to ensure that the crack does not expand.

Renco Tip: If you spot water or moisture coming from a crack the faster you act the better. Ottawa’s quickly changing weather patterns can cause the crack to grow or lead to more water issues.
