This guide describes the use of a high solids content, cold liquid-applied elastomeric waterproofing membrane subject to intermittent hydrostatic pressure in a waterproofing system intended for installation on cast-in-place concrete vertical surfaces. Typical uses for these systems include planters and foundation walls with drainage system and others. The major components to be considered for a below grade building wall waterproofing system are the structural wall or substrate to be waterproofed, waterproofing membrane, membrane protection, and drainage system. The following considerations are detailed: (1) compatibility; (2) continuity; (3) substrate: strength, density and moisture content, admixtures, release and curing agents, finish, dryness, and joints; (4) waterproofing membrane: adhesion to substrate, terminations, and penetrations; (5) treatment and design of reinforced, unreinforced, and expansion joints; (6) protection course: impact resistance, compatibility, ancillary provisions, thermal insulation, and drainage composites; and (7) drainage system: drainage course, backfill, and drainage pipes. Illustrations of footing, treatment of vertical corners, and pipe penetration for the waterproofing system and treatment of reinforced and unreinforced joints are given.

1.1 This guide describes the use of a high solids content, cold liquid-applied elastomeric waterproofing membrane that meets the performance criteria specified in Specification C 836, subject to intermittent hydrostatic pressure in a waterproofing system intended for installation on vertical cast-in-place concrete surfaces.
