Foundation Leveling: Pier & Beam Foundation
Each home is different and there are different ways to have a home leveled. If your home has a pier and beam foundation with a dirt crawl space it will be a lot easier to level since it is much easier to access. A few methods that are used with pier and beam foundations include:
- Installing new piers
- Leveling girders and joists
- Retrofit damaged beams
Installing New Piers
Piling or piering is the technique of driving steel pipe pilings
to remedy failing building foundations and to correct foundation settlement.
Push piers consist of sections of galvanized or epoxy-coated steel pipe that are driven into the soil with a hydraulic ram.
Helical piers use screw piles with steel shafts. The lead section, with one or more helixes attached, provides the needed bearing capacity. The piers are screwed into the ground with a hydraulic torque motor.
With either system, one or more steel piers are driven to rock or a suitable soil bearing layer and are connected to the foundation through a metal head assembly. Once a suitable bearing stratum is reached, each pile is tested to a force greater then required to support the structure
Leveling Girders and Joists
A damaged floor joist generally causes a low spot in the floor above the joist and the bottom edge of the joist is below its neighboring joists. You need to raise this low spot to restore the floor to it original height. Girder and joist jacks (also known as “steel lally columns”) can be installed at key locations along the structure. Once in place, the floor can be “jacked up” in an attempt to lift the floor back to a level position.
If a contractor finds a joist is severely damaged, the easiest way to repair it is to firmly attach another board of equal or larger size alongside the questionable joint. This board is called a “sister board” and the whole process is known as “sistering.”
Steel foundation shims are thin pieces of fabricated steel that are approximately ¼” thick. When re-shimming a foundation, these small pieces of steel are stacked one on top of each other. They’re added until the foundation reaches the desired h
eight. Fixing a foundation may necessitate installing an additional 2-4 shims in certain areas.
Foundation Leveling: Slab Foundation
If your home sits on a slab your home can be leveled by:
- Helical Piers
- Drilled Bell Piers
- Concrete Pilings and Piers
- Resistance or Steel Push Piers
Foundation Leveling: More Information
Of course always getting down to the root of the problem is imperative, so that the problem doesn’t occur again. If you have foundation issues due to moisture-related issues you need to find the leaks and potentially have to install a new water drainage system. In some cases, your home’s foundation just wasn’t adequate to hold the weight of your home. Working with the right company will help you ensure your home is safe and stable in the future.
