When it comes to the garage, foundation problems can be just as common as they are in the home. Because garages are normally built on concrete slab foundations, they are especially prone to foundation settlement and cracks. Foundation problems in attached garages are particularly dangerous, as they can affect the home as well. It is good to examine your garage regularly for signs of foundation failure, such as cracks in the wall or floor, bowing or leaning walls, sloped or uneven floors, sticking doors or windows, gaps and spaces between walls and the floor or doors and windows, and settling, shifting or cracking foundations
Most structural issues in the garage are caused by a settling or shifting foundation. This foundation movement happens when the soil beneath the foundation shifts due to changes in the moisture content or other factors. the most common causes of foundation movement are:
The best way to support a sinking or shifting foundation is to use a process called underpinning. Underpinning is the use of piering products to lift and stabilize the foundation from underneath. There are several common underpinning techniques that can be used to correct the foundation movement in your garage. These techniques are fairly complicated processes and should only be performed by experienced foundation repair contractors
The first of these processes is the installation of steel push piers. The first step in this installation process is to install a bracket, excavate around the bracket, and drive the piers deep into the ground until they reach stable soil. Then, the weight of the structure is transferred onto the piers, which are utilized to lift the foundation back to its original position. The foundation is now stabilized and future foundation issues are prevented.
The next type of underpinning method, similar to steep push pier installation, is helical pier installation. Helical piers are used in much the same way, except they are not driven into the ground like steel piers are. They are similar to large screw in appearance, and are threaded into the ground, minimizing the need for extra equipment and disturbance to the work site. These piers are often used with lightweight structures, or when the soil conditions are challenging.
