Bowing Foundation Wall Repair - St. Charles, MO

Case Study: Bowing Foundation Wall Repair - St. Charles, MO

Problem: Due to poor drainage and expansive clay soils, this foundation wall was bowing inward 2-1/2 inches. There were multiple leaking foundation cracks as a result of the bowed wall.

Solution: As requested by our customer, the wall would be pulled back to the plumb position (vertical). This required that the foundation wall be excavated to the footing depth and eight Grip-Tite Foundation Wall Anchors be installed. Once the foundation wall was straightened and stabilized, all the foundation cracks were repaired from the exterior. Next, an elastomeric, seamless basement waterproofing membrane was spray applied to the concrete wall. A heavy duty vapor barrier was fastened over the membrane to protect it during the backfill process. An exterior sump pump system was installed as well as drain-tile to prevent hydrostatic pressure against the wall in the future. The trench was backfilled 2/3 full with clean gravel to aid in drainage and to provide a cushion between the foundation wall and the expansive soils. Finally, an electronic float switch controller with an alarm, was mounted inside the basement to monitor sump pump performance and to alert our Customer of any problems with the sump pump should they occur.
