UNSPSC 12164904: Inorganic waterproof coating

A slurry waterproofing agent injected into a cement mixture where it coats the particles of cement, silica and ceramic minerals.

UNSPSC 12164904 Inorganic waterproof coating, a Commodity code, encompasses sealants, coatings, and related application materials used by state and local governments to repair and maintain pavements, structural concrete, and parking infrastructure. State and local procurement under this code focuses on crack sealants for asphalt pavements, deck coatings for parking structures, joint sealers for bridge and pavement applications, and penetrating and epoxy sealers for concrete protection. Issuing bodies span a wide mix: city public works departments (San Antonio, Waxahachie, Salem), county transportation and procurement offices (Santa Clara, Collin, Hartsfield-Jackson Atlanta International Airport's Department of Aviation), state departments of transportation (Texas, Illinois, Maine), and special-purpose transit or construction authorities (Harris County Department of Education, University of Texas System). Recent activity shows city and county governments sourcing crack sealants and deck coatings through IFBs and RFPs; state DOTs procuring joint sealers and road-grade materials in bulk through competitive bids; and airport and educational institutions seeking specialized coating and sealant work as part of larger renovation and pavement contracts.

Geographic spread of recent opportunities centers on Texas (San Antonio, Waxahachie, Lubbock District, Collin County, Harris County), California (Santa Clara County), and secondary activity in Oregon (Salem), Maine, Georgia (Atlanta), and Illinois. The Texas Department of Transportation appears as a repeat buyer of joint sealers and related tools, while county-level procurement in Texas shows consistent demand for crack sealants, asphaltic concrete crack repair materials, and road-grade coatings. Representative recent opportunities include the City of San Antonio's IFB 6100019897 for PolyFlex Type 3 crack sealant (bids due October 16, 2026) requiring Texas DOT Standard Specifications compliance and three-year contract terms with annual price adjustments; Santa Clara County's ITB-PRC-FY27-0066 for pavement installation and repair services (estimated $2.5 million, bids due August 31, 2026) covering asphalt, concrete, and decomposed granite repairs; the City of Salem's Bid No. 267087 for vehicular deck coating on Pringle Parkade (bids due September 29, 2026) requiring ten years' prior commercial experience and Oregon prevailing wage compliance; and the State of Maine's RFQ for deck sealant systems and epoxy polymer concrete (quotations due July 15, 2026) establishing a master agreement for all state departments with estimated annual usage of 5,000–8,400 gallons across multiple product categories.
