Pier & Polyurethane Foundation Repair in San Antonio, TX

The stability of homes and their foundations has a lot to do with the condition of the soil upon which they are built. There are many underground forces which affect this stability, yet there are several methods of foundation repair to correct these compromised foundations. Read more about how to identify a foundation crack and how to perform a foundation crack repair.
 
 

What causes foundation cracks?

There are two main factors that contribute to foundation cracks; the weather and the type of soil.

 

How do these two factors cause foundation cracks?

 

Severe drought

A period of severe drought can cause the soil to dry out and crack, causing it to actually pull away from the home as the moisture leaves the soil and causes it to contract. This can produce a foundation shift, which can lead to structural damage not only in the foundation, but to the overall structure of the house.

 

Extended rainfall

Conversely, a period of extended rainfall can cause the soil to expand. This happens especially in the clay-like Texas soil where the soil expands against the foundation of the house, causing pressure that can crack the foundation.

 

Plumbing leaks

Another common problem that may lead to a foundation repair need in San Antonio are the many plumbing leaks that allow copious amounts of water to seep out from underneath a home. This process is just like pouring rainwater around your house...constantly

 

When water leaks from faulty pipes like this, there is a constant source of moisture, which leads to major foundation repairs. If left unchecked, this can have extremely adverse effects on a home's stability and cause cracks in the foundation.

 

Clay soils

With the predominance of clay soils in mid to southern Texas, there is very little bedrock to anchor most types of piers that support the base of a house. Clay-based soils can put a large deal of force on the house as the soil expands and contracts.

 

When water is constantly leaking into the clay, the clay absorbs the water and expands, which can move the foundation of a house. If leaking plumbing is the suspected cause of moisture, then the house can be supported by piers until the faulty plumbing can be fixed.

 
 

How do you know if your foundation cracks?

Before a foundation cracks, there are several warning signs. Some of the warning signs that your home may be in need of foundation repair are:

  • Visible cracks in the foundation
  • Windows and doors that do not shut properly
  • Doorways inside of the home that are off center
  • Strange noises from within the home

 

How do you perform a foundation crack repair?

Foundation repair companies rely on multiple methods to perform a foundation repair, including concrete foundation repair and polyurethane foam jacking. In order to begin the foundation repair process, concrete piers are set under the house to stabilize the foundation.These piers use the weight of the home as a counterforce.
 
The concrete piers are pressed into the ground until they reach the resistance of bedrock. Then, workers can gently jack the foundation of the house back into a level position. This provides almost immediate results of total stability to the foundation.
 
Aftermath Foundation Repair in San Antonio uses pressed piers and polyurethane foam jacking as a better foundation repair strategy than concrete foundation repair. If a home is sinking in the center of the foundation, polyurethane foam can be injected into the area to stop any further settlement. It also seals off any further accumulation of moisture from getting into the area.
 
By using both foundation repair techniques together, you get the best of both words. The pressed piers bear the brunt of the tremendous pressure of the weight of the house, giving it a very high stability factor, and the polyurethane foam adds even more stability. These methods remove clay soil from around the foundation cracks to keep out the moisture, making it the ultimate fix for foundation repair in San Antonio Texas.
