Foundation Wall Anchoring
Cracks around your home, fissures in the chimney, or seepage in the basement can all be signs that you’ve got foundation problems. The good news is that wall anchors are a simple, quick solution that can stabilize your foundation and prevent further damage.
Because bowed walls are often the culprit when your foundation starts shifting, sinking, or cracking, it’s crucial to bolster up those walls as soon as you notice a problem. Foundation wall anchoring can save you from continued destruction and more extensive repairs that will cost you a lot of both time and money.
How Wall Anchors Work
Wall anchors use a combination of anchor rods (long pipes) and metal plates to stabilize a leaning wall and correct bowing. Rather than a full excavation and new walls, foundation wall anchoring works with your existing structure, which costs less and can be completed much faster.
To install wall anchors, we will drill several small holes into the foundation and dig several holes into the yard. Because the holes we dig are small, we can usually work without disturbing landscaping, patios, or decks. Once all the holes are completed, we drill an anchor rod through each of the holes we drilled in the foundation. The rod will extend several feet into the earth, nearly reaching all the way through the wall.
The next step is to install two metal plates onto each rod. One plate is secured on the interior side of the wall, and the other rests against the exterior. This creates a brace that strengthens and stabilizes the wall. We then tighten the interior plate with a lug nut, which pushes the wall back into the proper position.
Over time, the plates can be tightened as needed to correct any additional signs of bowing that occur. Finally, we will fill in the holes in the yard, and replace sod if needed. The whole process can usually be completed in one day.
What Causes Bowed Walls
There are many things that can cause walls to bow, crack or lean. If you’re concerned about wall bowing, look out for the following warning signs and causes.
Moisture: High water tables and ground moisture from rain and snow can put pressure on your foundation. Concrete-block foundations are especially at risk. Uncleaned rain gutters or misplaced downspouts can also add to foundation problems.
Trees and Bushes: When plants are placed close to the foundation, shifting soil from growing roots can add pressure to foundation walls.
Expansive Soil: Some soils expand and contract as they take on moisture and dry out. This repetitive cycle applies pressure to walls and foundation, and can cause bowing.
The best way to preserve your home’s integrity is to know what to look for and respond immediately at the first sign of trouble. Regularly inspect your home for cracks, and stop damage by having foundation wall anchors professionally installed.
