Foundation Repair in North Texas is very important. Foundations can be very expensive and take a long time to fix. It is better to invest in a good foundation before it deteriorates. In this article, I will cover some important considerations that must be made when fixing foundations in North Texas.
Foundation Repair: What to expect and how to do it. Understand what to anticipate and what is actually involved in foundation repair. Yes, foundation repairs aren’t a big event but are prepared by understanding what to anticipate. This North Texas house has about 4800 SF of living space. It required an over the lift of six and one-half inches.
The foundation repair method used was by pouring out a thick high-density polyurethane foam and then using steel bracing to secure the foam to the concrete piers. After the foam had set for six months, we poured another layer of high-density polyurethane foam over the first layer. Then we used wooden ties to anchor each pier together. It all should have been done correctly but it still took about a week to complete.
Other than concrete slab foundations, we also have helical piers and spindles. Helical piers is a metal support rod with helical teeth. Spindles are large pieces of wood that are used to support a heavy structure. Both of these methods can weaken a foundation.
Helical Piers: A good foundation repair process starts with the detection of helical piers. These are trenches with cracks or other anomalies on their surface. The cause of these piers may be soil movement, soil shifting due to the wind, or concrete loosening. The soil movement is most often found in southern states, where the soil is often sandy.
Once the piers are found, you can determine if a foundation will need to be lifted. There are basically two types of foundation lifts. One is the lateral pressure system which uses a series of steel columns connected to the bottom of the house foundation. This system provides very strong support on top of the soil load-bearing walls. The lateral pressure system is more stable and provides better structural integrity.
The second system is the sagging foundation system. It is also known as the drywall cracks system. This system is similar to the previous system but without the use of steel columns. When the soil pressure is removed, the house foundation now has a chance to move with the soil. If this happens, the house may tip over because the foundation isn’t strong enough to keep it up. This usually happens to older houses when there are more wooden components used in the foundation construction.
In the case of differential settlement, the soil level is higher than the roof elevation. Since the soil is higher than the roof, the foundation now has to cope with the extra weight of the soil on top of it. The soil pressure is removed by means of a pressurized fill material, which is then installed on the underside of the foundation.
Foundation uplift is another method used for dealing with soil movement. The main purpose is to restore a house to its original position when it experiences differential settlement. When a basement wall experiences heaving, vertical cracks may appear in the basement walls. There are different solutions to these problems, which include:
The above-mentioned four common types of foundation problems are considered the most typical ones. However, there are other types that are less common, yet equally problematic for many houses. One of them is the dampening of the interior spaces. Dampening occurs when the moisture content becomes too high, which then condenses on the concrete or beams forming a pothole. This will cause the foundation to become unstable and even cave in.
Another common type of foundation problem is caused by the heaving of the exterior walls. As the exterior wall progresses through an incline, there will be a progressive weakening of the structure. As a result, the water from rain or snow will collect in the gaps and form cracks, which will eventually heave upward.

If not stopped in their tracks, these cracks may even penetrate the foundation. The third problem is the cracking of the basement walls. This can occur because of the presence of poor insulation as well as the change in soil conditions over time.
Foundation repair and installation usually involve repairing the damages caused by the aforementioned common types of problems. Other possible repairs include basement waterproofing, fixing the plumbing, and replacing the exterior doors and windows. Foundation creeps may also be caused by poor plumbing systems or the presence of sills around basement windows. When this happens, the foundation may even collapse.
