In the diagram below, a bowing wall has been repaired and reinforced with carbon fibre straps. These straps are placed on the interior side of the foundation wall following wall realignment.

Outside, new waterproofing is done using an air gap drainage membrane and foundation coating. This redirects water to the weeping tile, mitigating the hydrostatic pressure which originally caused the bowing.
