How does National City's climate affect this service?
National City foundation work centers on pre-1950 craftsman and bungalow stock around the Historic Brick Row and Kimball Park, paired with older small-lot tract stock and commercial along Highland Avenue and the National City Mile of Cars. Cripple wall retrofit and slab leak voids dominate residential scope.. 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.
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.
