Underground Solutions

What Underground Solutions does

Underground Solutions, Inc. is a U.S.-based infrastructure technology brand operating as a wholly-owned subsidiary of Azuria Corporation (formerly Aegion Corporation), headquartered in Poway, California. The company specializes in pipeline products for water, sewer, and conduit applications, with its flagship Fusible PVC® product—a proprietary PVC formulation joined by a patented fusion process that yields a monolithic, fully-restrained, gasket-free, leak-free piping system compliant with AWWA C900 and certified to NSF 61 for potable water use. Complementary offerings include TerraBrute CR® restrained joint PVC piping, Vylon® closed-profile PVC slipliner pipe, WEKO-SEAL® pipeline seals, and Primus Line® flexible liner systems, collectively addressing pipeline installation, trenchless rehabilitation, forcemain renewal, and conduit/casing applications.

The company's revenue model is project-based, one-time sale of specialty infrastructure products priced via direct consultation with expert engineers rather than published price lists. Distribution is direct-to-customer enterprise field sales, supported by downloadable product brochures, installation demonstration videos, and an online consultation request form. End markets span five verticals: municipal water and sewer (primary), industrial, aviation, transportation, and Department of Defense, with active geographic reach across North America (U.S. and Canada) and the broader international market accessed through the Azuria corporate group, including Insituform Linings UK.

Underground Solutions holds registered trademarks for Fusible PVC®, TerraBrute®, and Vylon®, and a granted patent on the fusion process. The brand has raised approximately $48.6 million in private capital across four rounds between 2005 and 2014, with the largest being a $30 million Series 3 led by Riverwood Capital in July 2014. As part of Azuria's portfolio of 15+ water and pipeline infrastructure brands, Underground Solutions benefits from shared corporate services, cross-selling channels, and cooperative purchasing programs that support municipal procurement.
