Foundation repair is very common in East Tennessee. Rainfall plays a major role in basement waterproofing and hydro-static pressure can crack walls and damage foundations. Foundation wall cracks have several different causes, and each has its own unique solution. Concrete walls may experience small cracks as they cure. These are normal and may be no cause for alarm. However, walls cracking due to foundation settlement issues or expansive soils may require some repair work.
Foundation cracks come in many varieties, but all could be indicators of a problem with your foundation. If you have horizontal or vertical wall cracks, “stair-step” or diagonal cracking, bulging, buckling foundation walls, or pushing in at the bottom or top of the wall, you could need foundation repair.
Carbon Fiber Foundation Repair
We utilize several methods in foundation repair including carbon fiber. This repair process uses resin to sup
port the wall and make it stronger. Traditional crack repair methods use epoxy or caulk to seal the crack. Over time, the caulk or epoxy shrinks as it dries and allows the crack to re-open and allow moisture back into the building.
When the soils underneath your foundation fail to support the weight of your home, the foundation will begin to settle unevenly, and cracks will appear. As vertical cracks form and the wall or corner of the house begins to rotate, you will typically see cracks that are wider at the top or bottom.
Foundation cracks that are caused by settlement are very serious, and they will only get worse over time as the home continues to move. If you are concerned that your foundation may be cracking due to settlement issues, it’s best to address the problem as soon as possible.
If you have clay soils around your home, they can expand and contract significantly as they become wet. Wet clay soils can expand enough to put literally thousands of pounds of pressure on a foundation wall. This can force the walls inwards, sometimes causing them to bow, buckle and crack. Look also for walls pushing in at the bottom or tilting in at the top.
If left un-repaired, this kind of damage can worsen until the wall fails completely or is beyond repair. By addressing the problem of failing walls quickly, repairs can be completed in as little as a day.
Sagging Floor Joists in Crawl Spaces
Crawl spaces can sag when the support beams sink into the ground. They can also sink when mold and wood rot fungus weakens floor joists and girders, or when too few crawl space support posts are in place to adequately support the structure bearing down from above them.
As crawl spaces sag, the floor above can sink. As the floor sinks, it can pull on the partition walls attached to it, leading to drywall cracks. Sagging floors over crawl spaces can be corrected with support posts or floor jacks.
