How Are Wall Cracks Repaired?
When it comes to repairing wall cracks, the chosen repair option will depend on the root cause of the problem. Some possible repair solutions include the following:
Repairing cracks caused by differential settlement
Cracks caused by differential settlement are typically repaired via underpinning. This process involves using push, helical, or slab piers to extend the foundation down to load-bearing soil in order to stabilize it. Once the piers are in place the foundation is gently raised as much as possible without causing damage. This often closes the wall cracks.
Repairing cracks caused by hydrostatic pressure
A common repair solution for cracks caused by hydrostatic pressure is carbon fiber straps to stabilize the wall. The straps are applied and bonded to the interior surface of the wall using a high-strength epoxy resin. Once you paint over them, they’re virtually invisible.
Repairing cracks caused by improperly taped drywall
Here, the solution is much simpler. In this case, the crack can be fixed by simply retaping the drywall. This involves removing loose or damaged tape from the seams and joints and applying a new joint compound and tape. With proper sanding and finishing, the crack can be seamlessly repaired.
Choosing the right repair option requires an understanding of the underlying issues and the right expertise and tools to address them effectively. Therefore, it’s best to let the pros repair wall cracks.
