UNSPSC 12164900: Waterproofing agents

Chemical coating products used to increase water resistance of floors and walls of buildings.

UNSPSC 12164900 Waterproofing agents (Class) encompasses crack sealants and joint sealers that state and local governments apply to pavements, bridge decks, and parking structures to protect deteriorating asphalt and concrete from water infiltration and further degradation. The code sees active procurement across cities, counties, state transportation departments, and specialized districts, with recent solicitations ranging from straightforward material purchases to integrated repair and maintenance contracts. The City of San Antonio's October 2026 IFB for PolyFlex Type 3 crack sealant (2,100-pound pallets, FOB Destination, three-year term with annual PPI adjustments) and the Texas Department of Transportation Lubbock District's August 2026 IFB for 288 kits of Sikasil 728 RCS silicone joint sealant plus heavy-duty caulking guns exemplify the direct-buy segment; the County of Santa Clara's August 2026 ITB for Pavement Installation and Repair Services ($2.5 million estimated contract value) and the City of Waxahachie's June 2024 RFP for Annual Miscellaneous Pavement Repairs show demand bundled into larger service contracts where sealant application is one component among concrete and asphalt repair work.

Activity concentrates in Texas and California, with secondary presence in Massachusetts, Oregon, Maine, Illinois, and Georgia. Texas buyers—particularly Collin County (multiple road material procurements, June–July 2026), the Department of Transportation Lubbock and District 5 (joint sealant, June–August 2026), and the City of San Antonio (crack sealant, October 2026)—dominate the recent opportunity flow. California counties and cities (Santa Clara County, City of Waxahachie in Ellis County) procure pavement and trail reconstruction work that includes joint and crack sealing. The Maine Department of Administrative and Financial Services' July 2026 RFQ for deck sealant systems and epoxy polymer concrete ($250,000 security threshold, statewide master agreement with four-year renewal options) and the City of Salem, Oregon's September 2026 bid for Pringle Parkade deck coating (9,500 square feet, $100 per day liquidated damages, prevailing wage) illustrate geographic scatter into regional and municipal parking and bridge infrastructure. Most issuers require FOB Destination pricing with freight prepaid, product compliance against TxDOT or ASTM specifications, competitive general liability and workers' compensation insurance, and firm fixed pricing with no surcharges. Set-asides and prevailing-wage mandates appear in larger projects (Boston City Hall Plaza, $27.5 million, September 2026; UT Tyler behavioral health renovations, 20,000 square feet, September 2026) but not in routine material supply ITBs.
