Abstract: The invention provides a waterproofing membrane which does not require a removable release sheet but which nevertheless bonds to post-cast concrete and facilitates water-tight sealing at membrane-to-membrane overlaps. The waterproofing membrane comprises a carrier and pressure-sensitive adhesive (PSA) layers, an inorganic particle layer having particulate bodies which are partially embedded in the PSA and which have an average particle size less than the average thickness of the PSA layer, and an anti-submarining nano-silica-containing coating layer attached to un-embedded portions of the inorganic particles to prevent total embedding into the PSA when the membrane is rolled or unrolled, whereby water-tight seams are facilitated between overlapped portions of adjacently installed waterproofing membranes, and whereby the water-tight seam is achieved preferably using only detailing or waterproofing tape and without the additional use of a liquid primer, mastic, or other coating.

Abstract: Provided is a pre-applied waterproofing membrane having a waterproofing adhesive layer and an outer particle layer comprising synthetic polymer granules to protect the adhesive layer and to facilitate detailing at membrane-to-membrane overlaps. In preferred embodiments, the synthetic polymer granules are made from polymers selected from the group consisting of polyvinyl acetate, acrylic, and styrene butadiene copolymers or polymers. Most preferably, the synthetic polymer granules have round or spherical shapes that help to facilitate detailing at the building or installation site, such as sealing at membrane overlaps, and sealing around pipes or other details. Alternatively, the membranes may be made having side edges which are free of synthetic polymer granules, whereby a removable release liner strip can be used to prevent adhesive from sticking to the back of the membrane when the membrane is rolled up on itself for shipment.
