Patent

CA 2118183

An exemplary waterproofing membrane comprises a carrier layer having a non-bituminous pressure-sensitive waterproofing adhesive, a protective layer coated on the non-bituminous adhesive, and a second waterproofing adhesive layer on the other face of the carrier to permit adherence of the membrane to a cementious surface and to permit concrete to be cast against the non-bituminous layer and protective coating and to be bonded thereto when cured. Further exemplary membranes comprise a dusted layer on the protective coating to permit foot traffic. The membranes of the invention are useful in so-called horizontal and vertical lagging installations. Methods for waterproofing between cementious surfaces, in tunnels, and on concrete decks are also disclosed.
