Cutting-Edge Waterproofing to the Demanding Commercial Market

We have developed the finest teams and processes in the Pacific Northwest to install the best waterproofing materials in the world. For more than a decade, we’ve specialized in complex and challenging projects, refining our project management process until even unexpected jobsite variations are part of the plan.


Inland is proud to be in a very small, elite group certified to install such products as CETCO, Laurenco and Soprema PMMA products. These certifications mean that we are in a very small group approved and warranted to supply and install these lines. We are also approved applicators of all other manufacturers waterproofing and dampproofing products.

We set the standard in the demanding Pacific Northwest climate. We handle skyscrapers from below grade to the top floors, and enormous structures like Boeing’s nearly quarter-mile 777X building.

Our dedicated and tireless performance will keep your project on schedule. You don’t accept excuses, and neither do we.
