Many foundation problems are caused by poor drainage.
Here are three instances of improper drainage that harm post tension and concrete slab foundations.
- Rainwater runoff may be channeled to run under a house. This occurs when a neighbors yard is higher, or a hill is on one side of the house. The runoff erodes the soil under the foundation, leading to foundation failure.
- Gutters are absent, or when gutters are present, the downspout runoff is not directed away from the house. Water collects along the side of the house, the soil turns to mud, and loses its ability to support the perimeter of the foundation.
- Water collecting in a low spot next to the house leads to muddy soil and foundation failure.
Solutions for drainage problems include french drains and surface drains. Granite Foundation Repair installs both types of drainage.
