UNSPSC 31201637: Foam type water stop material for communication

A product that foams and hardens when injected into empty hole in pipeline and gaps as a foaming resin.

UNSPSC 31201637 Foam type water stop material for communication is a Commodity code. State and local governments procure under this code concrete sealant materials and application services for facilities and infrastructure maintenance, though recent opportunities show significant scope variation. The Orange County Transportation Authority (OCTA) in California recently solicited concrete sealant services under IFB 250318, specifying five distinct sealant types—penetrating sealer, water-based acrylic sealer, solvent-based acrylic sealer, epoxy or polyurethane sealer, and concrete surface preparation across 28 facilities including maintenance bases, park-and-ride lots, and streetcar platforms. Dallas County, Texas posted a bid for fusion tape (1 inch by 0.020 inch by 30 feet) in August 2026, though the source provides no additional scope detail. A Sourcewell cooperative procurement (RFP 061626) listing law enforcement equipment was tagged to this code but shows no meaningful connection to foam water stop materials or concrete sealants, suggesting potential coding misalignment in the source data. Issuing bodies include regional transit authorities (OCTA), county purchasing offices (Dallas County), and state-administered cooperative purchasing vehicles (Sourcewell on behalf of multiple Washington counties and broader participating entities).

Geographic activity centers on California and Texas based on recent postings. The OCTA opportunity represents the most detailed recent solicitation under the code—a $250,000, one-year prevailing wage contract (November 1, 2026 through October 31, 2027) requiring firm-fixed pricing per square foot with no price adjustments permitted during the term. OCTA requires bidders to hold a California Contractor's License (C-8, C-61, or D-06 classification), demonstrate three years of concrete sealant experience, meet an unspecified DBE participation goal, and complete mandatory OC Streetcar Roadway Worker Program training. The pre-bid conference was held September 30, 2026; bids closed October 14, 2026. All materials must comply with South Coast Air Quality Management District VOC requirements. The Dallas County opportunity (due October 1, 2026) provides minimal detail beyond the product specification. The code shows relatively light recent activity and mixed scope alignment, warranting scrutiny of how individual solicitations are actually tagged to this commodity classification.
