Insituform Technologies, LLC

Insituform Technologies, LLC, a Chesterfield, Missouri-based for-profit limited liability company, performs specialized infrastructure maintenance and remediation services for the federal government as a prime contractor (78% of recent awards) and as a subcontractor to larger engineering and construction firms. The vendor operates across a portfolio of nine federal awards spanning the past eighteen years, with combined potential value of $3.8 million, competing predominantly under small-business set-asides and work-for-others arrangements rather than large competitive vehicles.

The vendor's capability footprint centers on environmental remediation, sewer and water infrastructure inspection and repair, and industrial operations support. Recent representative work includes a $329 thousand firm-fixed-price catch-basin maintenance contract awarded by Air Force Materiel Command in September 2021 (performance extended through September 2026) under a Total Small Business set-aside, a CIPP (cured-in-place pipe) lining task under B & H Contracting Company as a subcontractor on a Department of Interior moraine park campground utilities design-build project, and a storm sewer inspection sub-award under Agviq LLC in September 2025 for TSCA soil removal and industrial operations work. The category concentration reveals primary work in hose and flexible tubing (three awards), plastics material and resin manufacturing, miscellaneous waste management services, and water and sewer line construction—reflecting a specialty in trenchless pipe rehabilitation and environmental remediation.

Customer concentration is narrow and defense-heavy. The Department of the Army Corps of Engineers Engineering District Vicksburg anchors 78% of recent awards by count and 96% by combined potential value, with three awards totaling $3.1 million. The Department of the Air Force Materiel Command, the Department of the Navy Installations Command, the Department of the Navy Naval Facilities Engineering Command, and the Department of the Interior National Park Service National Office round out the customer set, each with single awards. The vendor places one task order under the Environmental Remedial Action Contract parent vehicle. Activity is sparse and episodic—two awards in 2009, one in 2010, then a long gap before reengagement in 2021, 2023, and 2025—with only one award (the Air Force catch basin maintenance contract, $329 thousand potential value) reaching ultimate completion within the next twenty-four months and therefore exposing that work to recompete. In its subcontractor role, Insituform performs specialized pipe and infrastructure rehabilitation services under prime contractors Agviq LLC and B & H Contracting Company on Corps of Engineers and Department of Interior water resources projects.

The vendor holds seven named subsidiaries, including Corrpro Companies, Inc. (which carries a Self Certified Small Disadvantaged Business designation), Am-Liner East, Inc., Insituform Technologies USA, LLC, and Ocean City Research Corporation. The subsidiary structure and SDB designation suggest capability depth in corrosion control, pipeline rehabilitation, and environmental remediation, though these designations and subsidiary operations are not independently corroborated by the prime contract award footprint shown in the source.
