Case Studies: Walnut Cove, NC- Bowing Basement Wall Stabilized Using Wall Anchors

Tuesday, July 12th, 2016 By Jaimie Hooker


Challenge

Hydrostatic pressure was the main culprit in causing the large horizontal crack running across the entire basement wall in this Walnut Cove, NC home. While the horizontal crack had been visible since the home was purchased over 14 years ago, the homeowners had noticed within the last five years, the wall was beginning to bow out. The “L” brackets that were installed to prevent the wall from moving years ago, had now failed. The steel brackets were not only bowing with the wall but were rusting at the bottom due to moisture.  The homeowners were left with not only a foundation problem, but their original solution was now a contributing new problem. Ignoring the growing concerns was no longer an option. 

 

Solution

System Design Specialist, Andrew Howard, designed an extensive plan to provide a lasting solution to stop the bowing wall, and allow the wall to straighten over time. The rural yard size would allow for the Basement Wall Anchors to be the face of solution for the homeowners.

The Foundation Team began the basement stabilization by digging small holes in the yard, twelve feet from the foundation wall. The purpose of having the holes dug twelve feet away was to reach virgin soil for maximum resistance and stabilization. As the holes on the exterior of the home were dug, one-inch thick anchor rods were drilled in the basement wall and connected to the earth anchor in each exterior hole. A low-profile galvanized wall plate was then placed on the interior of the basement wall at each rod location. As all components of the Basement Wall Anchors System are connected and tightened, the exterior holes are tamped and filled. The bowing basement wall is now permanently stabilized.

During dry seasons as the clay soil shrinks, the Basement Wall Anchors can be tightened, allowing the for the bowed wall to become straightened.

The homeowners are relieved to have their foundation problems corrected, without the worry of their basement wall falling in!
