Resins and Polyurethane Foams
for Low Pressure Injection Crack Repair
The question often
arises as to which is better in concrete crack repair: epoxy or polyurethane
foam. If the crack needs to be structurally repaired and the area needs to be
as strong or stronger than the concrete around it, the answer is simple: epoxy.
The answer is less simple if the crack needs only to be repaired to prevent
water leaking through it.Either can accomplish this task, and applicators typically
choose the material they are mostexperienced with.
Epoxies have the advantage of introducing structural integrity, whether needed
or not.Polyurethane foams are often more versatile when the crack is actively
leaking at the time of repair,or if the area is still subject to limited movement.
Today, it is often more relevant to ask about the latest techniques, equipment
possibilities and resin characteristics formulated with these materials. This
article limits itself to repair of concrete cracks.
