By the end of this article, you will learn a lot.

  • How to tell if the walls are bowed.

The walls of your house are made of concrete. Dirt around your concrete block walls can cause foundation damage.

The soil gets heavy when it gets wet. The weight of the water pushes against the foundation.

The walls can only resist so much if they can hold the amount of pressure that is placed on them. Some of your foundation’s structural integrity can be lost due to cracking and bulging walls.

Every homeowner should know how to fix basement walls. We are going to talk about warning signs and solutions related to this issue and how to save money when implementing a fix.

What are the signs that you have a problem with a foundation wall?

The bulging of walls in your foundation is an indication of the severity of the damage.

Structural integrity needs to be protected from this type of problem.

If you are familiar with the warning signs below, you can fix the issue as soon as possible.

Interior Cracks

If you see cracks on the inside of your basement walls, they are bulged in response to the outside pressure.

Structural problems are usually not related to cracks that run vertically or horizontally. A foundation wall repair expert should inspect the cracks on the stairs.

Too much pressure coming in from the exterior can cause horizontal cracks.

Foundation wall failure occurs when the concrete walls flex inward until a fissure forms to relieve the stress from bowed.

Exterior Cracks

If you have a finished basement, you can see the cracks on the outside of your wall.

You have to check the same things. It’s not a sign of bowed basement walls if you see horizontal and diagonal cracking.

If the cracks are caused by bowed walls, they should be checked by a structural engineer.


There is a concrete wall under your home. When the pressure on the outside is very high, tilts can happen. The foundation wall can crack if it is close to the top.

If you want to make sure your wall is vertical with a square, you can take a visual inspection.


The pressure on the outside causes your wall to break.

There are visual signs of inward movement in your basement.

This can be tested using a straight edge in the middle of the wall.

Uneven Floors

Your entire house depends on your foundation to provide a level surface. One side of the home will be slightly higher than the other.

Since the floors above your foundation rely on a level concrete surface, you may notice that the floors in your home are not even.

Doors & Cabinets Not Shutting Properly

The walls in your home are the same as the floors are. The rest of the house can be affected by bowing foundation walls.

Your doors and cabinets are flexing.

The doors may swing open or closed on their own.

Bulging Walls

The movement in the walls on other floors of your home can be caused by the loss of structural integrity.

The movement of the foundation wall causes the walls above to flex outward or inward.

What Causes A Foundation Wall To Bow?

hydrostatic pressure in the dirt causes foundation walls to bulge. The ground is much heavier because of the rain or the amount of water in the ground.

The added weight of water on top of the dirt can cause your foundation to fail.

If they can’t hold back the weight, the foundation walls bow inward. Any type of soil can cause this movement. The amount of water it can hold is the most dangerous.

Another cause of pressure is frost heave. Cold weather can cause the water in your soil to freeze and place additional pressure on your concrete walls.

The most common cause is static pressure.

Large machinery like backhoes, excavators, or bulldozers used for landscaping projects can add too much pressure to the land and cause inward movement on the walls.

A tree root growing into your foundation can cause bowiness.

How Do You Fix Bowing Foundation Walls?

If left without a solution, bowing foundations can cause a lot of damage. There are permanent fixes like using carbon-fiber mesh, or installing an I-beam system.

Future wall problems can be prevented by these solutions. There is a different old-school fix that is more effective.

Install Earth Anchors

The beams that are sunk into the ground are called earth anchors.

A large hole is dug to accept the foundation wall anchor after a section of grass is removed.

Drill Through The Foundation Wall

The earth anchor placement is followed by holes being drilled into the wall. The hole is drilled from the inside of the basement to the anchor.

Your home can be damaged by drilling holes in it. Only a professional can do this process.

Attach The Earth Anchor

A steel rod is fed through the hole into the anchor.

Mount Wall Plate Inside

To attach the steel rod to the foundation wall, you need something on the inside. The threaded steel rod has a nut on it.

If a large plate isn’t used, there can be serious damage to the wall.

If you don’t use a plate to distribute the force on your wall, it can cause additional structural damage.

Restore The Landscaping

The holes for the earth anchor should be fixed. The holes need to be filled and the sod replaced.

Tension The Wall Anchors

The nut on your foundation wall needs to be tightened to place tension on the steel rod.

Adding stability to your foundation can be done with the help of the clamping pressure. The wall can be moved back to its original position.

How can I save money when fixing a wall?

When going through foundation repair, many homeowners look for ways to save money. There are some things you can do to save money.

If you get a permanent solution carried out by a professional first, you can save thousands of dollars.

Some homeowners try to find a solution that is more affordable. Temporary fixes require more money to be spent on a permanent fix than a permanent fix.

You can save time and money by getting an adequate solution.

If you solve the core issue yourself, you can save money on repairs. The most common cause of foundation walls is static pressure.

If you want to prevent soil saturation and added pressure on your concrete walls, you should install gutter, downspouts, and French drain. The cost of repairs can be reduced with the help of these solutions.

You can get a warranty from a concrete repair specialist.

Foundation problems can recur and require more wall repair after a period of time, even if they were done correctly to begin with.

We recommend connecting with a foundation specialist to evaluate your situation and needs.
