We install Epro fully monolithic waterproofing. Form damp proofing a dry area to heavy systems for the high-water tables. We install both blind side for lagging walls and positive side for the cast in place walls. I had a wonderful experience from start to finish! Very professional and experienced with what they do. I had my deck waterproofed and it looks amazing. They really have outstanding attention to every little detail and I couldn't be happier with the way my deck turned out. I plan to have them return and waterproof my walkway this summer!

Trinity Waterproofing and its brother company Trinity Metals were established in 2004. In that time, we have finished literally hundreds of projects ranging from personal homes to large condominium projects. No matter the size of the project, our focus is in the details to build systems that will last for years of trouble-free use. The Pacific Northwest is one of the wettest areas in the world, with some of the most difficult terrain to work with, from hill sides to the windy beaches. Trinity Waterproofing has overcome a wide variety of residential and commercial waterproofing challenges that are unique to the industry.

What's new?

We do a lot of remediation work,, finding work like this that was never done even close to right from day one. The cost of replacing beams that were never protected adds up quickly. Make sure to hire a professional in the industry so your building will last as long as you do.
