Most homes that show expansive soil distress…
should not have the foundation repaired because they are not sufficiently damaged to warrant repair. (US Army Corps of Engineers)
Discovering the cause of substandard slab performance…..
can be difficult and time-consuming. There may be multiple possible sources of distress and damage in the house. For instance, there may be a large oak overhanging the foundation, poor drainage around the foundation and no automatic watering system.
To discover the cause you could have the offending tree removed and then wait at least two years to see what benefit you get. This procedure can be repeated until the foundation is acceptably stable.
There may not be any obvious cause. When nothing seems to work, the final step is to retain an engineer to seek his advice. If there is a structural safety issue or a structural integrity issue and underpinning will solve the problem, then foundation repair may be a necessary option.
Most money spent on foundation repair…..
Foundation repair is like rolling dice…….
according to Richard Rash, a retired foundation repair contractor in the Dallas/Ft. Worth area.
Competent foundation repair……
requires a soil report from a licensed Texas geotechnical engineer. Even so, very few people are willing to spend $800 to $1200 for a soil report, especially when foundation repair contractors are telling homeowners that they don’t need a soil report.
