North County Inland sits on expansive clay valleys and decomposed-granite foothills. Bonsall settlement is usually drought-driven shrink-swell on clay or hillside slope creep. Repairs almost always pair underpinning with drainage retrofit; either alone is half the answer.. Inland clay-soil cracks are more often structural — diagonal at door corners, widening through summer, closing through winter.

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.
