Tremco Barrier Solutions
Tremco Barrier Solutions, formerly Koch Waterproofing Solutions, became a Tremco company in 2003. Tremco Barrier Solutions offers moisture, thermal, vapor and air barrier systems to builders of new homes
throughout North America. As the leading provider of residential waterproofing for new construction, Tremco Barrier Solutions helps builders protect their homes and reputations with the #1 (TUFF-N-DRIŪ Basement
Waterproofing System) and #2 (Watchdog WaterproofingŪ) brands of foundation waterproofing. Through a dedicated network of contractors throughout North America, Tremco Barrier Solutions offers the highest
quality and best-performing products in the industry. Our customers consider our Technical Service, Sales and Marketing Support organizations as additional reasons why they choose to do business with us.
Tremco Barrier Solutions products and systems don't stop at the top of the foundation wall; however the "Horizon" Foundation Finishing System protects the exposed above-grade portion of the foundation wall,
providing insulation and moisture management performance, while giving the exterior wall aesthetic appeal. Moving up the exterior wall, the Enviro-Dri™ Weather-Resistant Barrier System is offered as a more effective
alternative to housewraps. Enviro-Dri completes the building envelope by protecting the exterior walls and interior wall cavities from moisture intrusion, reducing uncontrolled air movement through the walls, and allowing
trapped moisture to escape through the permeable membrane.
Tremco Barrier Solutions' vision is to passionately and profitably lead the residential barrier solutions markets.
WTI (Weatherproofing Technologies Inc.) offers a comprehensive inventory of roofing and general contracting services to building owners and facility managers. WTI is one of the largest roofing maintenance service providers in North America with millions of square feet of roofing under contract covering thousands of roofs with service agreements.

Canam Building Envelope Specialists
For building owners with high performance building goals, eliminating gaps, cracks and holes in the building envelope is the first simple step to improving building performance.
Because the building envelope is the first line of defense against weather, insects, pollutants and other environmental factors, maintaining its integrity is critical to meeting building performance and energy consumption goals.
The experienced Canam Building Envelope Specialists staff understands the cause of effect of uncontrolled air leakage. We specialize in air barrier solutions for government, education, healthcare, commercial, condominium and manufacturing markets.
