Put braces for cracked foudation to prevent walls from deflecting
Vertical cracks in new foundation walls may appear as the concrete shrinks during the drying process. In older concrete basement walls of Regina homes, vertical cracks may result from compressed dirt exerting pressure on the foundation. (Please see wall straightening / bracing.) Typically, small vertical cracks do not impact the structural integrity of the wall, while larger vertical cracks can be effectively sealed with a polyurethane-based material.
Horizontal cracks are often the result of soil pressing against the exterior of a foundation wall. The wall space above or below the crack may push into the basement, causing the surface of the wall to become uneven. Depending on the severity of the crack, the solution may involve vertical steel bracing or foundation reconstruction.
