Wall Anchor System Solutions

Wall anchor systems are a common solution for many buckling, bowing or cracking basement walls, usually caused by lateral pressure from surrounding, loose soils.

Foundation Wall Anchor PlateHydrostatic pressure from moisture build-up in the soil is the most common cause, but wet clay soils or frost heaving in lower temperatures can also cause foundations walls to give under pressure. A basement wall with these issues can allow mold, infestations and leaks into your basement, leading to unhealthy conditions. Left unaddressed, this can threaten your home’s structural integrity. Early symptoms can include drywall or plaster cracks, uneven floors and stuck doors or windows.

Thrasher uses its patented, proven and warrantied Geo-Lock Foundation Wall Anchor System. Built from corrosion-resistant galvanized steel, the system first places an anchor in compact, load-bearing soil in your yard, with a minimum level of disruption. Another anchor is placed at a key point on your foundation wall where it is secured in the yard anchor by a steel rod held by an adjusting mechanism on the basement anchor. This immediately prevents further cracking, bowing or buckling, and over time using the adjustment mechanism, returns the wall to its original position, closing cracks and restoring structural integrity to your home.

Frequently Asked Questions

  • Hairline vertical cracks are not uncommon as concrete walls cure. If the cracks grow over time or become more than 1/8 inch wide, more serious issues might be at play, including a sinking or sagging foundation creating vertical pressure on the wall and threatening your home’s structural integrity.

  • Hydrostatic pressure from expanding soil due to moisture changes can exert tremendous lateral pressure, causing horizontal cracks to form in basement walls. Left unattended, these horizontal cracks tend to grow with time creating more serious issues, potentially a full wall collapse. 

  • Using the best materials, installed properly by trained technicians, and with a minimum amount of maintenance, foundation wall anchors work extremely well, providing an almost permanent solution to cracking, bowing or buckling basement walls. Installed across thousands upon thousands of homes all across the country over many decades, foundation wall anchor systems are one of the most common and proven foundation solutions.

  • The cost to install wall anchors can vary, depending on the overall number required for a wall anchor system to stabilize and restore your wall. Using the highest quality materials properly installed to provide the best long-term solution, wall anchors can range from $600-800 each. Compared to the cost of a foundation rebuild or the damage that can be done to your home from structural weaknesses, wall anchors are well worth the investment.

  • Basement walls that are bowing, buckling or cracking are best anchored with a wall anchor system that repairs the basement wall and restores your home’s structural integrity. The best way to anchor a basement wall is to first place an anchor in compact, load-bearing soil outside in the yard, joined to a wall anchor on your foundation wall by a steel rod that can be adjusted. This allows your wall to slowly return to its original position, closing cracks and restoring foundational strength.

  • Wall anchors are tightened by an adjustment nut on the end of the steel rod in the basement wall anchor, secured to a yard anchor by the rod. This is normally done with a wrench that turns the adjustment nut. Wall anchors should be tightened every 3-4 weeks when the ground outside is dry and not frozen, until the wall is straightened.
