A seamless, monolithic membrane created by applying a liquid coating to a building’s exterior forms a protective shield against the elements. This liquid, typically composed of polymers, elastomers, or bitumen, cures to create a continuous, waterproof layer that adheres tightly to the substrate, bridging cracks and gaps. Common examples include liquid-applied flashing, roof coatings, and below-grade waterproofing.
This method offers superior protection against water intrusion, air leakage, and moisture damage, contributing to enhanced building durability, energy efficiency, and improved indoor air quality. Its flexible nature allows for accommodation of building movement and thermal expansion, reducing the risk of cracks and leaks that can occur with traditional sheet membranes. While waterproofing has existed for centuries, the use of liquid-applied technologies represents a significant advancement offering improved performance and ease of application in complex building designs.
