A solid foundation is the key to any successful endeavour, but what happens if your home’s foundation begins to bow inward? With trusted service, expert technicians, and a 10 year, transferable warranty, Summit Drain stands by our bowed wall repair in Ottawa so your home can continue to stand.

Signs of Bowing Foundation Walls
- Cracking – horizontal cracks along the wall and diagonal cracks in the corners are strong indicators.
- Doors and Windows – a bowing wall may make doors and windows stick in their frames.
- Bulging – a visible bulge in the wall particularly along the bottom is a serious warning sign.
- Other signs could include uneven floors, water leaks, or sagging ceilings.
When Should You Be Concerned with Bowing Walls?
There is never time to procrastinate with the possibility of bowing walls. From the first time you notice any warning signs as listed above, it is important to take action. Any bowing from 1cm should be a concern, and bowing that exceeds 2 cm needs to be repaired immediately.
Our Bowed Wall Repairs in Ottawa
Repairing a bowing wall comes in several stages. After determining there is a bow to the wall, vertical carbon fibre straps are to be fixed to the wall.
First, the wall is prepped by grinding clean paths on the wall at approximately 1 metre intervals for the vertical straps to adhere to. Horizontal and diagonal cracks are fixed with either an epoxy or polyurethane injection. Then, a sill plate at the top of the wall and a footing plate on the floor are attached along the clean paths.
Next, the carbon fibre is mounted to the wall, and epoxy is applied to solidly stick it fast to the wall. Finally, the carbon fibre is secured to the sill plate above and the footing below. The hardening epoxy-saturated carbon fibre becomes a permanent attachment that stops any further movement in the wall.

How Much Does Bowing Basement Wall Repair Cost?
Repairing a bowing foundation wall costs will vary in price depending on how many walls there are and how many straps will be needed. In general, each carbon fibre strap costs between $700-800. When placed approximately 1 metre apart on the affected walls, the repair cost, including labour, may rise to between $3,000-5,000. This could be considered a minor price to pay to keep your foundation wall from falling in on itself.
