HydroBond 402-CCSM is a high performance membrane for the external waterproofing of below-ground foundation structures, basements, water holding tanks, culverts and tunnel bases. Pliable and durable, the membrane negates the requirements for a smooth blinding and protection boards when used as a ground level radon DPM.
A composite of LDPE and a non-woven geotextile fleece, the membrane has excellent crack-bridging capabilities at places where cracks occur within the concrete. When pre-applied before the concrete, the wet concrete is absorbed into the fleece, integrally bonding it to the membrane. This results in a high-strength bond with exceptional peel adhesion qualities, preventing water migration between the concrete and the membrane, even when damaged.
HydroBond 402-CCSM can also be post-applied to the wall surface, and can be used alongside other Newton products to provide a coordinated and combined approach to the waterproofing of the whole structure that includes protection against water penetrating through construction joints, through and around service entries and to movement joints.
