Preapplied waterproofing bonding coating and systems and methods involving the same and methods involving the same

A method for establishing a waterproofing bond with post-cast concrete, comprising:

• (A) providing a substrate chosen from formwork, a waterproofing membrane established by application of a previous coating composition or a rollable/unrollable sheet-form membrane having a carrier layer, a building surface, a civil engineering surface, or any combination of the foregoing substrates;
• and
• (B) applying onto the substrate, to establish a waterproofing bond for concrete that is subsequently cast against the substrate, a waterproofing bonding coating composition which is an aqueous synthetic polymer emulsion system comprising:
• (i) at least one film-forming synthetic polymer present in the amount of 5% to 100%, preferably in the amount of 50% to 100%, more preferably in the amount of 80% to 100%, based total dry weight of the aqueous synthetic polymer emulsion system, wherein the average particle size of the at least one film-forming synthetic polymer is in the range of 5 to 150 nanometers;
• and, optionally, (ii) a surfactant in the amount of zero to no greater than 1%, and preferably zero to no greater than 0.5%, all percentages of polymer above being based on total dry weight of the aqueous synthetic polymer emulsion system.
