The Washington State Department of Transportation (WSDOT) is working on an $11.6 million initiative that includes replacing three miles of bridge deck pavement along the U.S. 2/Interstate 5 Interchange in Everett.

Crafco geocomposites will serve as the foundation of the project, extending its longevity, the company says.

Composed of a resilient textile material with a specialized polymer modified asphalt backing, Crafco GeoTac HS is designed to enhance roadways by locking out water, chemicals, and debris from entering the subbase, extending pavement service life, a press release says.

Its waterproofing material significantly exceeds ASTM standards for tear strength, puncture resistance, and grab tensile strength, making for easy installation as well as long-term reliability, the company says.

More than 22,000 vehicles use this roadway daily, on average.

Crafco GeoTac HS was one of only two products considered that complied with WSDOT engineering specifications, the company says. The final determination was made by WSDOT and subcontractor Jonnic Construction. Jonnic has managed or consulted on more than two million square feet of geocomposite work and is considered the region’s expert, the press release says.
