Foundation repair companies use a variety of corrective methods in order to fix a foundation – and the best method can only be determined once the foundation repair service has had a look at the house and sees what is causing the problem. Below is a look at the six major methods used in foundation repair. These are not DIY projects – a professional foundation repair service should be contacted and consulted if there are problems with a foundation. A qualified foundation repair company can come in, inspect the foundation, and decide what the most cost-effective, lasting solution will be for the home.

These are concrete columns that are poured into drilled holes in the ground to support the foundation. If the piers need to be placed outside the house, the process is quite simple and cost-effective. Concrete Pilings Similar to piers, concrete pilings are ready-made concrete columns that are placed underneath the foundation rather than poured in. They take half the time of piers, and last as long as the foundation will. This solution can result in a cost-savings over steel pilings. Steel Pilings This is the same concept as concrete pilings, but with steel. Steel, of course, is less apt to erosion and wear problems that are sometimes seen with concrete. However, this is a more expensive alternative to concrete, and is not always an option, as it may not be appropriate to place the pilings underneath the foundation. In that case, concrete piers will be used. Mudjacking/Slabjacking This method, using concrete (AKA “mud”) or polyurethane resin, pumps the material underneath the foundation to lift it back to its proper space. This is especially used for foundations that have succumbed to sink holes and severe erosion problems. Soil/Chemical Injection Potassium ions and ammonium salts are water-soluble chemicals that are non-toxic, and prevent surrounding soil from absorbing water. By doing so, soil will be prevented from swelling and tilting the foundation. This is best used for minor foundational problems where lifting is no more than 1.5 inches. Root Barriers When roots from trees and plants begin to push and move a foundation, it’s time to put in root barriers to keep damage from going too far. Mostly solid objects and sheet material is used to prevent the roots on a property from growing into the foundation. They will be stopped by the barrier, and grow in the opposite direction or adjacent to the barrier.
