UNSPSC 12164905: Waterproof admixture

A waterproofing agent that comes in powdered or liquid form used for mixing with concrete at the time of pouring of concrete. It increases water resistance of concrete structure itself.

UNSPSC 12164905 Waterproof admixture, Commodity, encompasses sealants, coatings, and protective treatments that state and local governments apply to concrete pavements, bridge decks, parking structures, and airport infrastructure to prevent water infiltration and extend pavement life. Recent solicitations show state DOTs and county transportation departments procuring penetrating concrete sealers, epoxy polymer overlays, hot-poured joint sealants, and rejuvenation products for routine pavement maintenance and emergency repairs. Issuing bodies span state transportation departments, counties, municipalities, airport authorities, and university systems, with activity concentrated among transportation maintenance programs and capital improvement initiatives funded through state grants or local option sales taxes. Geographic spread includes Maine, Texas, Georgia, California, Wisconsin, Illinois, and Florida, with the heaviest recent activity in Texas and Georgia reflecting intensive pavement-preservation programs across multiple counties and municipalities.

Representative recent opportunities include the State of Maine Department of Administrative and Financial Services' RFQ for deck seal and epoxy polymer concrete products (due July 15, 2026), establishing a master agreement for statewide procurement of penetrating sealers and double-layer deck treatments; the Texas Department of Transportation's solicitation for Sikasil 728 silicone sealant in 40 oz sausage kits for bridge joint applications in the Lubbock District (due June 26, 2026); the State of Illinois Department of Transportation District 5's emergency small-purchase procurement for hot-poured joint sealant (due June 10, 2026); Dane County, Wisconsin's request for bid on no-box hot-pour sealant for crack filling in asphalt and concrete pavements (due April 2, 2026); and the City of Urbana, Illinois's invitation to bid for joint and crack sealing on Portland cement concrete pavement across city roads (due April 21, 2026). The code shows consistent demand for commodity-level sealant and admixture supply tied to preventive maintenance cycles, with pricing typically fixed for annual or multi-year contract periods and delivery often structured to multiple county or state locations on an as-needed basis.
