Central San Diego housing stock spans 1920s craftsman bungalows on raised post-and-pier through 1980s slab-on-grade tracts. La Mesa foundation work splits between cripple wall and post-and-pier rebuilds in older homes and slab or perimeter underpinning in newer ones. Plumbing-leak voids under slabs are a frequent driver here.. We account for local conditions in every job.

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.
