UNSPSC 12162602: Organic clay stabilizers

UNSPSC 12162602 Organic clay stabilizers is a Commodity code that covers soil stabilization materials and services used by state and local governments to prevent erosion, compact clay, and stabilize ground conditions on public infrastructure and facilities. Recent solicitations show state and local buyers are procuring both the materials themselves—such as clay-based grout mixtures and stabilization compounds—and the associated application and construction services. The issuing bodies include city and county public works departments, waste management agencies, and facility maintenance divisions. The work spans soil consolidation, pressure grouting, erosion control through hydroseeding and stabilization, and remedial ground treatment on transportation corridors, landfills, and transfer stations.

Activity under this code is concentrated in Florida and California. The City of Orlando issued IFB26-0227 for soil stabilization pressure grouting at a site adjacent to Florida's Turnpike, soliciting sealed bids for installation of 13,320 linear feet of grout piping and placement of 6,600 cubic yards of sand/cement grout, with responses due October 22, 2026. Sacramento County's Department of Waste Management and Recycling issued RFB #2026-RFB-0049 for erosion control services using hydroseeding to stabilize landfill slopes across multiple county facilities, with annual performance required before wet seasons; the County offers a 5% local business preference and a 2% micro-business preference. Pasco County, Florida issued an indefinite-quantity RFQ for supply of large copper sulfate crystals and liquid copper sulfate on an as-needed basis, with responses due June 26, 2026. These three opportunities represent the recent activity visible under this code; geographic spread is light and concentrated in two states.
