UNSPSC 12164800: Water reducing agents

Additives used to control coagulation by dispersing the particles.

UNSPSC 12164800 Water reducing agents, a Class code, covers concrete and masonry sealants, coatings, and waterproofing products that state and local governments procure for infrastructure rehabilitation and facility maintenance — particularly at water treatment plants, elevated storage tanks, and public buildings where concrete repair, epoxy coating, mortar lining, polyurethane injection, and interior tank coating systems are specified within larger construction contracts. State and local water utilities dominate recent activity under the code, alongside higher-education facilities management and specialized municipal water districts. The work is typically bundled into broader construction or rehabilitation RFBs and RFPs rather than purchased as standalone material orders, with contractors selecting specific sealant and coating products to meet detailed technical specifications and compliance standards, including prevailing wage, apprenticeship, and Build America Buy America requirements where applicable.
