Energy savings, storm water retention, and aesthetic benefits are driving forces behind the growth of green roofs. Significant performance improvements in root resistance, drainage layers, waterproofing membranes, and lightweight growing media and plants have increased service lives to 40+ years. This presentation will review various sub-grade waterproofing, plaza deck assemblies, and green roof technology. We will analyze various types of materials, including pre-manufactured membranes, spray-on or brush-applied coatings, and expandable and/or injectable waterstops. This presentation will focus on design concepts, detailing, surface preparations, application methods, and troubleshooting for typical below-grade and roof level waterproofing concerns.
