    One of the most common problems faced by dams and locks is the ingress of water through cracks, joints and failed water stops. Our team has had the opportunity to stop 40 gpm leaks in dams with polyurethane grouts that set up within seconds, as well as pin point and stop moisture wicking through hairline cracks with polyurethane grouts with very low viscosity…but how do we do it? 


    Choosing the right material for the job is essential for the longevity of the repair.  Using hydrophobic and hydrophilic polyurethane grouts will not be a temporary fix but a permanent installation when the right product is chosen and installed correctly.
