Wall Crack Repair
A basement wall crack is a sign of failure caused by stresses, preliminary design, improper curing, etc. One of the dangers of a structural crack is its effect on the reinforcing bar. The reinforcing represents one of the main structural values of the concrete.
Unprepared cracks allow moisture, road salts, and other contaminants to penetrate and attack the rebar. The rebar deteriorates, losing its structural value. Losing the entire structure is often the result.
There are several solutions for wall crack repair – epoxy injections, hydraulic sealants, crystallization, and drain tubing.
Some of these are designed to restore the structural quality of the original concrete, making it, in most cases, as good as new. It creates a waterproof seal to air, water, chemicals, debris, and other contaminants. Some systems carry the water from the crack to a drainage system, depending on the other waterproofing work that may be done.
