Abstract
An epoxy sealer/healer formulation for sealing and strengthening cracked concrete comprising an epoxy resin, an amine and a dialkylene triamine-alkylene oxide adduct, where the formulation provides a modulus and/or compressive strength at least that of uncracked concrete and effective for penetrating a concrete crack at a rate of at least 10 mm/min for a crack 0.5 mm wide when applied by gravity feed. The epoxy sealer/healer preferably has a viscosity of less than 100 centipoise and a tack-free time of less than 12 hours. The epoxy sealer/healer is advantageous in being able to bond to moist concrete surfaces. A method of using the epoxy sealer/healer for sealing and restoring the strength of cracked concrete is also set forth.
