Foundation Wall Repair Methods
- More than three inches – If your foundation wall has moved inward more than three inches, professionals can use wall plates or c-channel anchors. These methods both use outside anchors placed in your soil and high-strength threaded steel rods that lead to your wall. Wall plate anchors use inside steel “plates” that are attached to your wall, while c-channel anchors use long steel beams. Once attached to your wall, the plates or beams are torqued until they pull the foundation back outward.
- Less than three inches – If your foundation wall has moved less than three inches, experts will most likely choose Fortress Invisibeam carbon fiber straps (the only strap system that can stabilize three inches of movement). These straps are anchored to the top and bottom of your wall, while the strap itself is cemented into your concrete using epoxy rivets.
Foundation Crack Repair Methods
When foundation walls bow or shift, there tend to be cracks. Sometimes, these cracks are wide enough to pose a structural risk to your foundation. Sometimes, the cracks don’t pose a structural threat to your home, but they can still allow water to seep through. In both cases, experts recommend sealing and stapling the cracks.
- Epoxy crack injection – Experts always recommend sealing any cracks using a 2-part epoxy injection. This high-strength epoxy will fill the crack and prevent further water seepage.
- Carbon fiber staples – These high-strength staples are cemented into your wall along your crack. As another carbon fiber repair method, these staples prevent cracks from growing larger and reinforce your foundation wall.
