How To Repair A Cracked Basement Wall

Cracks in basement walls are a common problem, especially in older homes. Luckily, they are usually not a major structural issue. However, they can be a sign of a more serious problem, such as foundation settlement. Also, they can allow water to seep into your basement, which can lead to mold and mildew growth.

If you have a cracked basement wall, it is important to repair it as soon as possible to prevent further damage. But before you start repairing the crack, you need to determine what caused it in the first place. This will help you choose the best repair method.

What Causes Basement Wall Cracks?

There are several things that can cause basement wall cracks, including:

Foundation settlement: As a house settles, the weight of the structure can cause the foundation to sink. This can lead to cracks in the basement walls.
Soil movement: The soil around your home can move due to changes in moisture content or temperature. This can also cause cracks to develop in the basement walls.
Hydrostatic pressure: This is the pressure exerted by water outside the basement walls. If the water pressure is too great, it can cause the walls to crack.
Thermal stress: This is the stress caused by changes in temperature. When the temperature changes suddenly, the basement walls can expand or contract, which can lead to cracks.

How to Repair a Cracked Basement Wall

Once you have determined the cause of the crack, you can choose the best repair method. There are many different methods available, but the most common include:

Epoxy injection: This is a method of repairing cracks by injecting epoxy into them. The epoxy will fill the crack and seal it, preventing water from seeping in.
Hydraulic cement: This is a type of cement that expands as it dries, which can help to fill cracks and seal them.
Wall anchors: These are metal devices that are used to stabilize the basement walls and prevent them from cracking further.
Carbon fiber straps: These are straps made of carbon fiber that are used to reinforce the basement walls and prevent them from cracking.

Which Repair Method Is Right for You?

The best repair method for you will depend on the size and severity of the crack, as well as the cause of the crack. If you are not sure which repair method is right for you, it is best to consult with a professional.

Preventing Basement Wall Cracks

There are a few things you can do to help prevent basement wall cracks, including:

Control the moisture around your home: Make sure that your gutters and downspouts are clean and in good working order. Also, slope the ground away from your home to prevent water from pooling around the foundation.
Stabilize the soil around your home: If the soil around your home is loose or unstable, it can put pressure on the basement walls and cause them to crack. You can stabilize the soil by planting trees and shrubs around your home, or by installing a retaining wall.
Inspect your basement walls regularly: Look for any cracks or other signs of damage. If you find any problems, fix them as soon as possible to prevent further damage.
