Crack Repair for San Ysidro homes, done by an experienced San Diego County foundation crew. Not every crack is a structural crack, and not every crack needs the same fix. Hairline shrinkage cracks at the slab edge are cosmetic.

How does San Ysidro's climate affect this service?
San Ysidro foundation work centers on 1950s-80s small-lot single-family stock and older multi-family inventory near the US-Mexico border. Cripple wall retrofit on the older raised-foundation stock, slab leak voids on aging tract copper, and Tijuana River Valley drainage influences drive most calls.. We account for local conditions in every job.
Should I use epoxy or polyurethane?
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.
Can I just use a DIY crack kit from the hardware store?
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.
