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, Commodity tier, covers concrete sealers, epoxy overlays, and joint sealants that state and local governments apply to bridge decks, airfield pavements, parking structures, and roadway joints—products actively procured by state DOT districts, counties, municipalities, and airport authorities to extend pavement life and manage water infiltration in aging infrastructure. Recent solicitations show mixed demand: concrete sealers and epoxy polymer overlays anchor the market, with joint sealing compounds as a secondary application. The State of Maine Department of Administrative and Financial Services, Office of State Procurement Services, posted an RFQ on July 1, 2026 (due July 15) for deck sealant systems and epoxy polymer concrete products—penetrating sealers in multiple container sizes, single and double-layer deck treatments, and epoxy overlay kits to be stocked as a master agreement for all state departments through August 2031. The Texas Department of Transportation District office in Lubbock issued an RFQ on June 26, 2026 (due June 26) for Sikasil 728 RCS silicone sealant in 40 oz cartridges for bridge joint sealing. Illinois Department of Transportation District 5 posted emergency procurement for hot poured joint sealant on June 5, 2026 (due June 10).

Issuing bodies span state DOT offices, county highway departments, municipal airports, and regional authorities. Maine, Texas, and Illinois show the most recent activity; Georgia airports (Hartsfield-Jackson Atlanta, Savannah, Wayne County), California counties (Santa Clara), Wisconsin counties (Dane), and Florida municipalities round out the geographic spread. Maine's master-agreement structure indicates longer-term commitment—the state estimates annual consumption at 400 gallons of penetrating sealer, 400 gallons of single-layer treatments, 5,000 gallons of double-layer treatments, and 2,000 epoxy overlay kits. Pricing in these procurements emphasizes FOB destination delivery to dispersed state facilities, with firm pricing required for twelve months or longer. Texas and Georgia airfield projects show concentrated demand for joint sealing as part of runway and taxiway rehabilitation, often bundled with crack sealing and pavement marking services. No set-asides or minority preferences appear in recent postings; standard prevailing-wage and bonding requirements apply to larger projects.
