An improved back-up wall in building perimeter wall systems that include a porous masonry exterior wall, an interior finished wall and moistureproof to back-up wall separating the two to prevent moisture penetration beyond the exterior wall, is provided by sealing the joints between rigid panels forming the back-up wall with moistureproofing material, building the material up over the seams and reinforcing the seal by embedding a reinforcement strip in the moistureproofing material over the joint. Cost savings and a superior back-up wall can be provided by precoating panels forming the back-up wall with moistureproofing material before installation.
