About Us

Our Experience

118845764286495.QyHSmqVmIdVE3LgvCdFT_height640At Peter Ross Group our management team has over 80 years of combined experience in the waterproofing industry. Most of this experience is in the high rain areas of Western Canada, Washington, Oregon, and Hawaii.

Our Understanding

  • We understand that when assessing a project it is more than utilizing a length-times-width mentality, and that each new construction or restoration project has its own unique set of challenges.
  • We also understand the strengths and weaknesses of the materials and systems we install. That is why we incorporate a full fabric reinforcement into all of our black line systems. This allows the system to experience the expansion and contraction of the substrate and not crack and tear, which adds to the life of the system.
  • We add our experienced input to that of the architect, owner, developer, and general contractor to establish effective criteria for system requirements and cost estimating.

The Peter Ross Group of Companies installs more than 5,000,000 square feet of waterproofing each year.

We never compromise the system criteria or quality

Quality Assurance


118845764286491.hlcUqSzfJgaFsBLCyvTv_height640Quality assurance is a practice that begins at the project’s conception and remains an integral part of our operation long after the system has been applied.
