Crack Repair in Coronado, CA.
Crack Repair for Coronado 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.
Why is crack repair different in Coastal San Diego?
Coastal stem walls show shrinkage cracks earlier because of marine moisture cycles. Most are cosmetic; salt and efflorescence at the crack edge tell us when the crack has been wet recently and needs hydrophobic polyurethane instead of epoxy.
What's included in crack repair in Coronado?
- Crack typing: shrinkage vs settlement vs lateral movement

How does Coronado's climate affect this service?
Coronado has the most extreme salt-air exposure in San Diego County. Historic Victorian and Craftsman stem walls in the Village, 70+ years old in many cases, see salt-corroded rebar and anchor bolts that fail decades earlier than equivalent inland stock. Naval Air Station North Island work and Coronado Cays tract repair round out the call mix.. Coastal stem walls show shrinkage cracks earlier because of marine moisture cycles.
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.
