Understanding Waterproofing Membranes

Waterproofing membranes act as a protective barrier that keeps water from penetrating roofs, foundations, and walls. There are several types available, including liquid-applied, sheet, and cementitious membranes, each suited to different surfaces and climates. Choosing the right membrane depends on factors such as the structure's exposure to moisture, movement in the substrate, and expected foot traffic. Proper surface preparation and professional installation are essential, since even a high-quality membrane will fail prematurely if applied incorrectly.
