Why Waterproofing Matters


For more than 25 years, Sawtooth Fortified has partnered with general contractors, owners, architects, and consultants to deliver comprehensive waterproofing solutions on some of the largest commercial projects in the Northwest and beyond. From below-grade foundations and plaza decks to roofing transitions and building envelope systems, our experienced crews help protect structures from water intrusion, preserving long-term durability, performance, and value.

Waterproofing in Action


  • Below-grade foundations
  • Plaza decks and roofs
  • Building façades and curtain walls
  • Parking structures

Waterproofing Built to Last

Water intrusion is one of the most destructive forces a commercial building will ever face. Left unchecked, it can lead to structural deterioration, corrosion of embedded steel, mold and indoor air quality concerns, damage to interior finishes, and costly repairs that impact both operations and occupant comfort. At Sawtooth Fortified, we provide comprehensive waterproofing solutions that safeguard your building envelope from day one—protecting your investment, extending the life of your structure, and providing long-term peace of mind.

Effective waterproofing requires more than simply applying a membrane. It demands a thorough understanding of how water interacts with a building, where vulnerabilities exist, and how multiple systems must work together to create a continuous barrier against moisture intrusion. Our team specializes in identifying critical transition points, penetrations, terminations, and other high-risk areas to ensure long-term performance throughout the life of the structure.

Whether protecting below-grade spaces, occupied areas, or exposed structural elements, our approach is focused on durability, constructability, and long-term value. Through ongoing manufacturer training, industry certifications, and a commitment to quality workmanship, Sawtooth delivers waterproofing systems designed to perform in demanding environments while helping owners reduce maintenance costs and avoid premature building repairs.

Sawtooth is reliable and professional with strong attention to detail. Their team is knowledgeable, efficient, and delivers clean, high-quality work on every project I have worked with them on. They communicate well, stay on schedule, and take pride in their work. I highly recommend Sawtooth for all your waterproofing needs.

Amaterra Winery

On this close to home project, Sawtooth's scope of work included Amaterra's below grade waterproofing with Tremco's 250 GC. Applying at a thickness of a minimum of 120 ml's this structure will be leak free from many elements that will be trying to protrude into the concrete walls. Sawtooth has been asked to start the caulking portion of the project here soon! Material is being supplied by Emrick, sealants used will be Tremco Spec 1, sidewalks will consist of SL2.

Hotel Chamberlin

At this renovation project of the infamous Shleifer Furniture store located on MLK on the East side of Portland, Sawtooth played a vital part in bringing the new up and coming Hotel Chamberlain to life! Our scope to this project was to help identify weak structural points on the outside exterior brick siding. Our masonry restoration division spot pointed, relayed brick and brick repair on the window lentils.
