þ       Masterseal® 845A

MASTERSEAL 845A admixture is a one-component polymer powder for spray-application onto soil and rock. The product is mixed with water in the spraying nozzle to hit the substrate in the form of a paste. The product sets within 5-10 minutes (tack free) and will generate tensile strength and bond strength over the next hours, days and weeks. Through good bond to most substrates, high elasticity and high tensile strength the ground stability and stand-up-time is substantially improved. Sprayed concrete can be applied against the membrane as soon as it has set and the typical bond strength concrete to membrane will be more than 1.0 MPa.
