What is a Bowing Basement Wall?

Bowing basement wall happen when they curve or lean inward due to external pressure from the soil outside your home. It’s most noticeable in the middle, as the pressure forces the less-reinforced part of the wall outward.

Basement walls usually bow in the middle, but the first signs of it starting to happen are walls cracks that run either horizontally, diagonally, or in a stair-step pattern.

Why Do Basement Walls Bow?

The most common factors that cause to basement walls bowing are as follows:

1. Poor Drainage

In Alberta, homes need to be ready for heavy winter snow and lots of rain because these forces can dramatically affect your basement. If the ground gets saturated, gutters, downspouts, and extensions are supposed to stop the water from gathering near the house’s foundation and basement. However, without adequate drainage systems like these, the water will collect around the basement walls, pushing against them inward.

2. Hydrostatic Pressure

In areas of Alberta with lots of rain and expanding soil, houses may have structural issues. This is due to the soil expanding when wet and contracting when dry, which puts pressure on house foundations and basement walls. Over time, this pressure can cause walls to bend and crack.

3. Seasonal Freezing and Thawing

Alberta’s freeze-thaw cycles, especially in spring, can damage basement walls. The repeated freezing and thawing of water can cause walls to bend.

4. Foundation Settlement

The soil underneath your home is always in motion—shifting, sinking, and generally settling out from underneath your home. Sometimes, if a house’s foundation settles unevenly, it can cause basement walls to bend as pressure builds around the walls.

Repair Methods for Bowing Basement Walls

Restoring your walls to their original state usually demands precisely deployed supports and drainage systems. With Groundworks, you get the following repair solutions:

1. Basement Waterproofing

Basement waterproofing is a comprehensive way to keep water from damaging your basement foundation and causing mold growth. At Groundworks, our custom waterproofing solutions include sump pumps, interior drains, and vapor barriers to relieve the pressure around your walls.

2. Carbon Fiber Reinforcement, Steel I-Beams, and Wall Anchors

After waterproofing, structural reinforcement repairs the immediate signs of damage and prevents their further development. Depending on the severity of the damage, several methods could be employed.

  • Carbon fiber straps, offering strength 10x greater than steel, can be applied to the weakest parts of your wall to stabilize them and redistribute hydrostatic pressure across their entire surface.
  • The IntelliBrace™ System, our custom-engineered steel I-beams, secure against the wall from floor to ceiling, reducing bowing and stabilizing the home.
  • Wall anchors, feature galvanized steel rods installed into the soil around your basement that then connect to interior wall plates. Each rod is securely fastened and then tightened from the inside to counteract the outside pressure. This process can gradually return the walls to a straight position and allow for any cosmetic repairs.
