What is a Foundation?
The foundation is the part of a home or building that is in direct contact with the ground. Its purpose is to transmit the load of the home or building to the ground and stabilize the structure.
Are There Different Types of Foundations?
The most common types of foundations are:
- Concrete Slab
- Crawl Space (conventional)
- Basement Foundation
What Causes Most Foundation Problems?
Soil conditions cause most foundation problems. Shifting soil and expansive clay soils create problems for homes or buildings with slab foundations, crawl spaces, as well as those with full basements. When expansive soils become saturated with water, they expand and push upward into the foundation. As the soil dries, it shrinks and the foundation settles. This heaving can cause cracked foundations and damage throughout the home’s interior.
What are the Most Common Types of Foundation Problems?
Generally, there are 2 major sources of foundation problems.
- Settlement – The unnatural sinking of the foundation or portions of the foundation below the original grade.
- Upheaval – When the foundation or portions of the foundation raise above the original grade.
These 2 sources of problems often lead to other headaches over time, such as damaged basement walls, doors that stick or a wet basement.
Getting to the Root of the Problem
To repair foundation problems, specialists need to get to the root of the problem. They do this by examining the home and investigating the visible symptoms. Common symptom areas might include things like:
- Why is the soil near or under the foundation saturated with moisture?
- Where, why and when is water entering the basement?
- What kind of foundation movement is happening—full movement or differential?
- Are these cracks signs of structural damage or simply cosmetic eyesores?
A certified repair specialist can perform a foundation inspection and determine which foundation repair methods may be needed to fix your home.
