How epoxy injection, polyurethane injection, hydraulic cement and carbon fiber straps differ in what they fix.
Not all cracks are the same, and neither are the repairs. Epoxy injection bonds concrete back together across a stable crack. Polyurethane foam injection fills and seals a crack and stays flexible. Hydraulic cement plugs active leaks quickly. Carbon fiber straps add strength to a wall that is starting to lean. The right method depends on what caused the crack and what you want it to do.
A hairline crack in a poured wall may need only epoxy. A crack that opens and closes with the seasons may be better served by polyurethane. A leaning block wall needs more than any crack filler. Homes around Nashville show all of these, so we start by reading each crack and explaining what a repair can and cannot do.
