Bedlam Foundation & Concrete Lifting Case Studies: Geo-Lock Wall Anchors and Sentry-Seal in Tulsa, OK

Thursday, August 15th, 2019 by Devin Jerko

Challenge

This basement in Tulsa, OK was suffering from some cracking in its foundation walls. These cracks were likely due to the expanding soil forces acting on the wall from the outer side. The crack in the wall was rather extreme and had a deflection of around 5 inches. A crack deflection of this size is a very bad sign and means that the wall could collapse at any time. The wall was in serious need of some immediate reinforcement.

Solution

Bedlam Concrete Lifting installed a total of five Geo-Lock wall anchors to permanently stabilize the basement wall. To start, the area outside of the wall was completely excavated down to the concrete footing and additional holes were dug about 17 feet from the wall. Rods were fed from the inside of the basement and were extended all the way to the outside holes. Geo-Lock anchor plates were attached to the outside portion of the rods and channel anchors were attached to the inside portion. The plates were then tightened until the walls proved properly supported. In this case, the wall was pulled back 3 inches, making the new total deflection of the wall 2 inches. After the walls were fully supported, a layer of Sentry-Seal was installed to prevent any leaks into the basement.
