Liquid-Applied Waterproofing for Roofs, Podiums and Wet Areas

This course explains how liquid-applied membranes work, compares the main chemistries, maps the standards used to classify them, and walks through build-ups for exposed and inverted roofs, podium decks and wet areas, ending with the preparation, thickness control and flood testing that make a specification enforceable.

Learning objectives

1. Explain how liquid-applied membranes form a seamless barrier and where the risks lie at the substrate, in moisture and in the details
2. Compare polyurethane, polyurea, acrylic and cementitious membranes on elongation, crack bridging, UV resistance and trafficability
3. Select a membrane and build-up for exposed roofs, inverted roofs, podium decks and internal wet areas
4. Specify substrate preparation, priming, thickness control, detailing and flood testing that make the membrane watertight
