Signs of bowing foundation walls

Foundation walls move inward primarily due to expansive soils and hydrostatic pressure on the walls from outside. However, foundation walls may also crack due to many other outside causes, including foundation settlement. Our foundation experts will accurately identify the cause of your home's foundation problems.

Below are images of several foundations that are showing damage from hydrostatic pressure and expansive soils outside the structure.

What causes cracked & bowing foundation walls?

How does moisture affect clay soils?

These two clay samples started out exactly the same in size, weight, and composition. The sample on the right was allowed to dry out, while the one on the left we kept moist.

If a small sample of clay can gain this much volume when it gets wet, just imagine how dramatic the changes are in the soil around your home!

The soils around your home can put enormous pressure on foundation walls. The amount of pressure they exert depends on four factors:

  1. The type of soil around the foundation
  2. The amount of moisture in the soil
  3. How far underground the foundation is
  4. The temperature conditions

There's constant pressure on your foundation walls from the outside, but the only thing holding up your foundation wall is the wall itself. Hydrostatic pressure, expansive clay soil, and frost can all exert enough pressure to cause walls to lean or even collapse.

Gutters and downspouts can also contribute significantly to foundation problems by allowing large volumes of water to collect in the soil around your structure.

If roof runoff is not directed away from your foundation, the soil around the foundation will become heavier and more expansive as it's saturated with water.

When foundation wall anchors won't work

Saving a wall with the PowerBrace™ system. This innovative system stabilizes bowing walls and can even straighten walls over time.

PowerBrace™ foundation wall reinforcement system

In some cases, a wall anchor system can't be used to repair a bowing wall because the yard outside the house isn't accessible. When we at The Foundation Guys encounter this kind of problem, we suggest that you install our PowerBrace™ Foundation Wall System or CarbonArmor® Wall Reinforcing System.

The PowerBrace™ System

The PowerBrace™ is a patented foundation wall repair system designed to stabilize failing basement walls and also allow for potential straightening over time.

This product is a great option when access to the yard outside of the home is not possible and bowing, buckling wall problems need to be solved.

The PowerBrace™ is an I-beam system that has several advantages over traditional "old school" systems.

This includes its rust-resistant zinc coating and a design that makes it possible not only to stabilize bowing walls, but also to straighten these walls over a period of time.

Installation of a PowerBrace™ system can be conducted quickly in your home, with no disruption to your lawn, gardens, foliage, or other landscaping.

CarbonArmor® carbon fiber foundation wall reinforcement

Strips add strength. When epoxied to the foundation wall, strips of carbon fiber fabric provide reinforcement that’s 10 times stronger than steel. The CarbonArmor® system is an excellent way to solve cracking, bowing foundation wall problems.

CarbonArmor® stabilizes cracked & bowing foundation walls with high-tech carbon fiber

When soil pressure causes a foundation wall to bow inward and crack, one solution is to stabilize and strengthen the wall using CarbonArmor® bracing technology.

The CarbonArmor® Wall Reinforcing System relies on the exceptional strength of carbon fiber fabric – 10 times stronger than steel.

Concrete is strong in compression, enabling a foundation wall to withstand extreme downward pressure. But concrete is weak in tension. A foundation wall can’t stretch or bend in response to sideways soil pressure, so cracking and bowing problems sometimes develop.

When installed against a foundation wall with special structural epoxy, CarbonArmor® fabric is exceptionally strong in tension. This reinforcement treatment enables a cracked or bowed foundation to withstand soil pressure without sustaining further damage.

CarbonArmor® repairs can be made quickly and affordably, and this low-profile repair is easily hidden with a coat of paint.

What NOT to do

A foundation repair is a big job -- something you definitely only want to do once! When you're repairing your foundation, beware of expensive options that will not actually fix your problem -- and watch out for quick solutions that just don't work.

Wasting time and money with total foundation replacement.

This extreme repair option damages the yard and requires the house to be placed on temporary supports. It's also expensive and time-consuming.

Total foundation replacement:

To undertake a job like this, you have to excavate the entire perimeter of your foundation -- including gardens, shrubbery, sidewalks, and other landscaping.

Next, the house is jacked up, and the floor slab and foundation walls are removed. Finally, the foundation is rebuilt, the house is repositioned and the soil is replaced.

This solution is extremely disruptive, expensive, and time consuming. What's worse, it's not really addressing the issue that caused the damage in the first place!

Your foundation isn't the problem -- the soil is! When you're done building that brand new foundation, you can count on the soil to press just as hard on the new walls. This will cause them to be damaged -- just like it did to the ones that preceded them.

If you're going to invest money in repairing your foundation, choose the solution that is not disruptive and will be warrantied for 25 years.
