Because of the constant movement of soil under structures
, foundations often crack, slip or slide. In order to lift the foundation, it must first be secured from further sinking problems. Concrete piles are used to secure the foundation of the home as well as any structure. These provide solid bearing to rest the foundation on. Concrete piles, however, do not provide the ability to lift.
The use of helical piers, also known as screw piers, is another method available for foundation stabilization. These piers are not designed for heavy lifting and are more recommended for securing lighter structures such as porches and outhouses.
The push pier or mini-pile system offers the ability to lift heavy foundations towards the original position. Push piers use a hydraulic system to drive into the ground until load bearing strata or bedrock is reached. Once the foundation has been secured from further settlement problems, the system can be used to lift the house.
It is highly recommended that the owner of the structure consult a foundation repair professional before investing in a house leveling project.
