If you have a concrete block or non-reinforced poured wall that is cracked and bowing inwards due to external pressure from expansive soils or hydrostatic pressure, or if you have a basement wall that is leaning inwards at the top, there’s a good chance it can be stabilized and possibly even straightened with a wall anchor.
Wall anchors consist of three main parts: the wall plate, earth anchor and connecting rod. They work by resisting the wall’s tendency to bow inward by anchoring it in competent soil beyond the foundation. Foundation Recovery Systems uses the Supportworks GeoLock™ wall anchor system. These wall anchors are made from heavy-duty galvanized steel and have been specially engineered to stabilize and straighten bowing basement walls.
Installing a Wall Anchor System
Installing a GeoLock wall anchor is actually fairly simple. First, a small hole is dug in your yard — typically at least 10 feet away from your foundation. A galvanized steel rod is then driven through a one-inch hole drilled in your basement wall and through the soil out to the excavated hole. A steel earth anchor is placed in the hole and connected to the steel rod. A low-profile steel wall plate is then placed on the interior side of the basement wall and connected to the opposite end of the rod. The hole is backfilled and then the system is tightened by turning a nut against the wall plate. The nut can be tightened incrementally over time to potentially straighten the wall. It is common for several anchors to be installed along the length of a wall to offset the external loads and allow for stabilization and straightening.
Wall Anchor Covers
After it’s installed, the anchor system’s wall plate can be concealed with a HideAway™ wall anchor cover. These covers blend into the wall, giving it a finished appearance. They can also be easily removed when it is time to tighten the anchor nut.
As mentioned earlier, the GeoLock wall anchor system not only stabilizes a bowing basement wall but may also straighten it over time. It anchors your home’s foundation walls to competent soils and can be installed with minimal disturbance to your home, lawn and landscaping. Once installed, the system’s wall plates can be concealed behind HideAway wall anchor covers.
