What United Felts does
United Felts is a U.S.-based manufacturer of Cured-In-Place Pipe (CIPP) liners, headquartered at 450 College Drive in Martinsville, Virginia, and operating as a wholly-owned division of Vortex Companies, LLC. The company produces a comprehensive portfolio of felt, UV-cured glass-reinforced plastic (GRP), glass-reinforced, and specialty liners for trenchless rehabilitation of sewer, storm, potable water, and industrial pipelines, with flagship brands including Felt CIPP Liners, UV GRP, EnviroCure, United Glass, UnitedBLUE, and the VeriCure fiber-optic curing monitoring system. Its technology stack combines polyester felt and fiberglass composite construction with proprietary chemistry — most notably the EnviroCure-Felt styrene-encapsulating barrier film (U.S. Patent No. 12,467,573) that reduces styrene emissions to below 1 ppm — and is supported by ISO 9001:2015, NSF-61, and BNQ certifications across ASTM F1216- and F1743-compliant products.
United Felts operates a 100% vertically integrated manufacturing model, from raw-material inspection through needling, coating, liner construction, and wetout (resin impregnation). It runs five wetout/manufacturing facilities across North America (Virginia, New Jersey, Florida, Texas, Montana) and added a German UV-liner plant through the April 2026 acquisition of BKP Berolina Polyester GmbH & Co. KG. The company sells direct to municipal governments, water and sewer utilities, and trenchless-rehabilitation contractors via an enterprise field-sales organization led by an SVP of Commercial Operations, supplemented by the Vortex Companies affiliate network (40+ global locations) and the MaxLiner sub-brand for small-diameter applications. Revenue is generated primarily through one-time liner sales (delivered wet or dry) and wetout services performed either in-house or on-site via mobile systems.
The business was formed in January 2024 when Vortex Companies consolidated three predecessor entities — Applied Felts Inc. (founded 1970, the first CIPP liner manufacturer in the Americas), FerraTex Solutions, and MaxLiner USA — under the United Felts brand. The company has produced over 200 million cumulative feet of tube and 100,000+ liners since 1970, and its current leadership includes President Matt Timberlake, SVP of Commercial Operations Tom O'Neill, Senior Quality Director Elios Torres Ramirez, and Technical Director Rob Stensby, with Vortex CEO Mike Vellano overseeing the parent organization.
