What is the best waterproofing system for our new plaza deck?
A. The best plaza deck waterproofing system depends on a number of factors including the complexity of the plaza and the installer’s experience with the waterproofing systems under consideration. Hot applied rubberized asphalt waterproofing systems minimize the likelihood for installation deficiencies but cost more than some of the more labor intensive membrane systems. Cold process systems have improved significantly and with cost constraints are well worth consideration. Thermoplastic sheet waterproofing can be cost effective and provide many years of satisfactory performance.
