A faulty home foundation can lead to structural damage that’s expensive to repair. In the worst case scenario, your house could sustain extensive damage and collapse. Since you don’t want either one to happen, call a professional for foundation inspection if you suspect that you have problems. Below you’ll learn what causes foundation problems, the signs and about the repair process.
The dirt underneath your home can expand and contract due to soil that’s too dry or ground that’s too wet. Dirt that contains an over abundance of clay is more prone to movement. In addition to the weather conditions, too much moisture underneath your home could be caused due to inadequate drainage around your home or plumbing leaks. If the soil underneath your home wasn’t properly compacted before the foundation was poured, this can also lead to foundation issues.
The signs of a cracked foundation are usually very noticeable, so if you see one or more of these signs, contact an expert as soon as you can. These include cracks in the walls and floor of your basement, stair step cracks in the masonry work of your home and basement walls that are pushing inward. Signs to look for inside your house are cracks above your doors and windows, and doors that are difficult to open and close.
Two of the most widely used methods of foundation repair are piering and slabjacking. Piering, which is also called hydraulic jacking, works by placing steel piers into the ground with hydraulic equipment. After the piers are in place, the foundation is secured to the piers and moved back into the proper position.
Slabjacking consists of drilling holes into the slab or piece of concrete that has sunken into the ground. Next, a mixture of cement, sand and other materials is pumped through the drilled holes. The mixture fills up the open gaps underneath the slab and as it pressurizes, it raises the concrete foundation back up and into position. The holes that were drilled are then filled with a special mixture of concrete.
After an examination of your foundation, a qualified inspector can recommend the best type of repair for your foundation problem.
