  • Publication number: 20200248446
    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.
