How To Fix A Foundation Crack.
There are several ways to repair foundation cracks, depending on the type and severity of the crack. Some of these procedures may require a permit so check local laws before you begin. Here are some options:
Epoxy injection: This method involves injecting epoxy into the crack to seal it and prevent further damage. This is a good option for small to medium-sized cracks.
Concrete resurfacing: If the crack is larger or more severe, you may need to resurface the concrete foundation to repair it. This involves chipping away a “V” shape in the damaged concrete and patching it with non-shrink grout.
Wall anchors: If the foundation crack is causing the wall to lean or bow, you may need to install wall anchors to stabilize the wall and prevent further damage.
Steel plate reinforcement. This involves placing and securing steel plates along the crack in a stitch-like pattern and patching the opening with non-shrink grout.
Final Note About Fixing a Crack In A Foundation.
It's important to note that these repairs should be done by a professional contractor with experience in foundation repair. Trying to fix a foundation crack on your own can be dangerous and may not properly address the underlying issue. Final note, these techniques are best performed from the outside, this means you must excavate the exterior, ideally down to the footing and backfilling with drainage stone (¾ crushed) to grade for best results.
