East County foundation movement is dominated by drought cycles, post-wildfire slope instability, and uncompacted 1970s tract fill. El Cajon helical pier work typically terminates in decomposed granite or weathered bedrock. Drainage retrofit is part of nearly every repair plan here.. East County diagonal cracks are common after long droughts when expansive clay shrinks under one corner of the house.

Epoxy bonds the two sides of the crack back into a structural unit, but only if the crack is dry and stable. Polyurethane expands when it contacts water and seals against active leaks but does not restore structural strength. If the crack is dry and the foundation is not actively moving, we use epoxy. If the crack is wet, weeping, or active, we use polyurethane and address the underlying movement separately.

For a hairline cosmetic crack on the inside face of a stem wall, a DIY kit is fine. For anything full-depth, anything weeping, or anything you suspect is structural, the DIY kits do not put enough product into the full depth of the crack. They seal the surface and the crack reopens behind the patch.
