UNSPSC 12164803: Structural water repellent

An additive used to make construction materials waterproof or water resistant by use of fatty acids to block pores within the concrete, preventing water passage.

UNSPSC 12164803 Structural water repellent is a Commodity code that covers protective coatings and sealants applied to building surfaces and infrastructure to prevent water intrusion and degradation. State and local governments procure this service primarily as part of facility maintenance, infrastructure rehabilitation, and new construction projects where water damage prevention is critical. The code appears in solicitations for waterproofing work on masonry, concrete, roofing systems, and water treatment facilities, often bundled with broader restoration or construction contracts rather than as standalone sealant purchases. Issuing bodies span municipal water districts, city public works departments, universities, and specialized facility management agencies. The University of Texas at Arlington, University of Wisconsin-Madison, West Basin Municipal Water District, City of Tybee Island, and City of Peoria have all solicited related waterproofing or facility protection services in recent months, indicating activity across educational institutions, municipal utilities, and general infrastructure authorities.

Geographic activity centers on the Southwest and South. West Basin Municipal Water District (California), the City of Peoria (Arizona), and the University of Texas at Arlington (Texas) posted solicitations in April and May 2026 for water treatment filtration projects, facilities waterproofing services, and infrastructure rehabilitation; the City of Tybee Island (Georgia) issued an ITB for restroom construction with exterior waterproofing specifications due May 19, 2026. The University of Wisconsin-Madison issued a general RFB for masonry worker services with an April 30, 2026 deadline, and the University of Texas at Arlington's RFP for blanket-order masonry restoration and facilities waterproofing (FM2026007) closed April 30, 2026, with a potential contract value of approximately $600,000 over six years, mandatory pre-proposal meeting April 16, 2026, and Texas prevailing wage compliance and HUB subcontracting goals of 1.39 percent for that special trades procurement.
