Homes located in places with heavy soils often experience bowing and cracking of their foundation walls. Pressure and compaction of the heavy soil, and occasional over-saturation with heavy rain cause immense external pressure on the walls, pushing them in. Too much pressure could cause a foundation wall to crack all the way through. Professional foundation repair in Des Moines can help homeowners to avoid a major foundation failure by fixing the issues while they are small.

Best Foundation Repair Techniques Used to Fix Bowed Walls

Anchoring
One of the most popular techniques used for foundation repairs is anchoring. This is done by experienced professionals, who do the repairs from inside of the basement. The perimeter of the basement floor is removed with the use of a jackhammer. Steel I beams are installed about every 4 feet along the bowing foundation walls, and are buried into the soil underneath the house and anchored to the basement ceiling with wooden support beams. New concrete is poured to keep the beams into place. Homeowners can also arrange for professional basement waterproofing in Des Moines to prevent future water intrusion.

Piering
Piering of foundation walls is called for when extensive problems have been detected. Severely bowed walls and large cracks may require piering repair techniques. To pier your home’s foundation, the repair crew will dig a trench around the exterior perimeter of the structure. Long steel and concrete piers are attached to the foundation and then buried under the soil. The trench is refilled and your landscaping is replaced. Additional repairs may need to be done inside of the basement as well.

Exterior French Drains
After a bowed wall is repaired, care must be taken so that the drainage around the home is improved. Basement repair specialists often install French drains around the perimeter of the home’s exterior. These drains help to divert rain and melting snow away from the home’s foundation. Wider gutters can also be installed onto the home’s roof, and these should be connected to downspouts that disperse the water at least 20 feet away from the home’s foundation. Proper grading of the soil also helps to lessen pressure on foundations.

Because of the amount of work that needs to be done to keep your basement in tiptop shape, you would do well to entrust it to experienced professionals, like Better Basements.
