From the beginning in 1994, Hydro-Stop was focused on manufacturing only waterborne products that provide superior waterproofing solutions for the entire building envelope.


With a commitment to hands-on service, the Hydro-Stop product line has a long history of working side by side with contractors. This hands-on approach is still evident in strong field service and as part of an integral commitment to customer service.

The Hydro-Stop product line represents a family of products that provide tested, trusted solutions that architects, building owners and contractors turn to for all their roofing and waterproofing project needs.


Hydro-Stop delivers sustainable roofing and waterproofing solutions that won’t come out of warranty until you tear the building down. Install a Hydrostop roof system, and simply maintain roof surface and recoat as needed to extend the warranty – literally for the life of the building.


Hydro-Stop was acquired by Quest Construction Products in 2007.


Quest Construction Products is the market leader in fluid applied roofing systems, coating solutions and pavement coatings that preserve, protect and restore commercial, industrial, residential, goverment and institutional spaces.
