Foundation Wall Crack Repair in Northern Ontario

Stair step cracks are a very common problem and a likely sign of foundation settlement.

Foundation cracks come in many varieties, but all could be indicators of a problem with your foundation. If you have horizontal or vertical wall cracks, "stair-step" or diagonal cracking, bulging, buckling foundation walls, or pushing in at the bottom or top of the wall, you could need foundation repair.

Foundation wall cracks have several different causes, and each has its own unique solution. Concrete walls may experience small cracks as they cure. These are normal and may be no cause for alarm. However, walls cracking due to foundation settlement issues or expansive soils may require some repair work.

Different types of foundation wall cracks

Foundation cracks vary in severity from a simple cosmetic issue to a major structural problem with your home. However, even serious foundation problems, when addressed early on, can be quickly and permanently fixed.

Cracks form in foundation walls for three main reasons:

Repairing foundation wall cracks

Whether the problem is expansive soils or unstable soils underneath your foundation, there are effective solutions that can permanently repair your foundation or structure.

Foundation pier systems are an excellent way to stabilize and potentially lift a foundation that is resting on soils that cannot support the weight of the home. Foundation piers are a permanent solution for homes that are settling, and they can be installed year-round.

They are advanced into the soils underneath the foundation via a helical blade.

Wall anchor systems, like our Geo-Lock™ Wall Anchor System, are ideal for stabilizing and potentially straightening foundation walls that are buckling due to pressure from expansive soils. Wall anchors use the soils beyond the foundation walls to exert counterpressure on failing foundation walls. This holds the walls in place in the short term, and it allows your contractor to attempt to straighten the walls back to their original position over time.

This solution requires access to the soils beyond your foundation walls. If exterior access is limited or not possible, we recommend installing the PowerBrace™ Wall Repair System as an effective solution.

Can I have a settlement issue if my foundation walls aren't cracked?

Cracks on interior walls can be a sign of a sagging crawl space rather than a settling foundation.

Sagging Crawl Spaces

Crawl spaces can sag when the support beams sink into the ground. They can also sink when mold and rot weaken floor joists and girders, or when too few crawl space support posts are in place to adequately support the structure bearing down from above them.

As crawl spaces sag, the floor above will also sink. As the floor sinks, it can pull on the partition walls attached to it, leading to drywall cracks. We can repair sagging crawl spaces with effective support posts.

Heaving Or Sinking Slab Floors

When the soils underneath slab floors settle or are washed away, the floor itself will begin to sag. Likewise, when the soils underneath a concrete floor expand, the slab will begin to lift upwards.

Either way, the movement of concrete floors can lead to cracks along drywall and the floor itself. We can help your repair concrete floors that are sinking or heaving.
