Tunneling Supply Warehouse

A Minority and Women Owned Small Business





Products and Experience for Your Project Life-Cycle

We are a one-stop shop for all of your tunneling and construction needs.  From planning to final execution, we are here to offer products and experience to get your job done by the most efficient means.


Founded in 2010, we saw a need for using polyurethane resins for stopping water infiltration.  After several years in the residential market, We joined forces with our vendors to solve complex soil stabilization and water infiltration issues in both the mining and civil industries.  Next, we expanded operations to include manufacturing parts to be used as conduits for the products we distribute, as well as our own line of acrylic resins.  Further, we expanded into the distribution of concrete reinforcing fibers, construction tools, drilling bits and manufactured steel support for tunnels and shafts.  Our manufactured steel meets Buy America and Made in America certifications.


Furthermore, by teaming with trusted and certified contractors, we can provide complete turnkey solutions.

Tri-State Waterstoppers, LLC is a minority, woman owned business certified by the NMSDC, the PA UCP, TX UCP and the NY UCP.
