Home Foundation Repair
Most foundation problems occur due to a few issues involving the soil supporting the foundation. Soil will shrink and swell as saturation levels fluctuate. This can result in foundation settling, or differential settlement. Since changes in soil moisture are what cause foundation problems, we must address the soil when considering how to repair the foundation.
Differential settlement simply means that one part of the foundation is settling at a different rate than another part of the foundation. The basic approach to foundation repair is to stablize and potentially lift the area of the foundation that has experienced the foundation settlement. In order to properly repair the foundation it is necessary to address the failing soil and the incoming moisture.
Signs of Foundation Problems
1. Cracked Bricks
Homes with cracked bricks may be experiencing foundation problems. Cracked bricks can arise from a number of different causes so it is important to have an experienced foundation repair expert diagnose the brick cracks.
Once the foundation repair project is complete, the cracked bricks can be replaced if needed and the mortar joints in the brick may be grinded out and re-pointed.
2. Wall Cracks
Wall cracks are very common signs of foundation problems. Cracks develop in walls because there is movement of the structure supporting the area near the wall cracks.
Many wall cracks may close up as the foundation repair solution is installed. Lift on the structure or footings can also result in possible damage. It is the decision to be made of the home owner on how much risk they would like to take in the founation repair project.
3. Foundation Cracks
When foundation cracks occur there is an immediate need to perform foundation repair. If you are unsure of whether or not your cracked bricks are a sign of foundation repair, you may dig down to the foundation the inspect the foundation for cracks.
Foundation cracks are simply a failure point. The foundation supports should be installed on the side of the crack that has settled most. Some homes may have settled in multiple directions and may require foundation supports on both sides of the foundation cracks.
4. Uneven Floors
Uneven floors and sloping floors may be caused by a number of factors. The footing supporting the outside of the home may need to be addressed, the footings supporting the home in the crawl space may need to be addressed, or the wooden framing in the crawl space could be causing the uneven floors.
As a homeowner, if you decide that you would like to attempt maximum lift, uneven floors may or may not correct. It’s important to understand that some lifting cannot be undone so make the decision on how much lift you would like with the suggestions from our foundation repair experts.
Steel Piers, aka Push Piers
1. Expose & Prepare the Foundation Footing
The first step to install steel piers is to excavate the dirt around the footing. The entire footing must be exposed and the dirt removed from the bottom of the foundation. This is done as preparation for the steel pier bracket to attach to the footing with a clear surface.
Before installing the bracket, the concrete from the foundation must be removed up to the wall. This ensures the strength of the steel pier system is directly underneath the area with the greatest load.
2. Attach Bracket and Drive Steel Piers
The steel pier bracket is installed flush with the side and bottom of the prepared foundation footing. The drive stand holds the steel piers as the sections of pipe are driven through a high strength pile guide sleeve.
Steel piers are driven deep into the soil until they reach load bearing stratum, meaning the homes foundation is essentially resting on a soil layer strong enough to support the home for a life-time. The steel piers are 100% load tested during installation.
3. Foundation Lifted and Stabilized
The steel piers are driven until they reach the proper resistance from the soil. At this point, the foundation has been stabilized. The weight of the home is resting on load bearing stratum.
Lift can be attempted to achieve correction. Lifting the home may result in further damage. Recommendations are provided by the installers about how much lift should be attempted but it is the decision of the home owner as to how much lift we will attempt.
