The Waterproofing Contractors Association (WCA) is a trade association dedicated to advancing the science of preventing leaks. Our network is comprised of manufacturers, distributors, contractors, and architects/engineers working together, as is our Leadership. Our membership reads as a “who’s who” in waterproofing expertise.  With this depth of resources, our members are ready to respond to the entire building envelope. 

Twice a year the member companies of the WCA come together to exchange state-of-the-art information on waterproofing, see the latest developments in waterproofing technology and products, and establish and renew personal relationships with colleagues in the field. WCA has a rich history of excellence in waterproofing and we'd love for you to play a part in our future.
