Who Is Westec?
Westec was established in 1994 to address a specific need in the industrial construction industry: chemical resistant waterstop and related products for secondary containment areas.
Westec has pioneered products and technologies for sealing secondary containment structures required in the petro-chemical and industrial facilities. Westec continues to provide the highest quality products and expert support for this critical segment of the industry.
Westec has a history of service and innovation in the secondary containment industry. With the Expansion Board Cap seal, numerous retrofit profiles and custom profiles, we develop products with the contractor and engineer in mind. These profiles, combined with the excellent technical support, material takeoffs, shop drawings and jobsite training, make Westec and The Greenstreak Group, the first choice for Secondary Containment waterstop.
