UNSPSC 12162601: Inorganic clay stabilizers

UNSPSC 12162601 Inorganic clay stabilizers, a Commodity code, covers soil stabilization and erosion control chemical products and services that state and local governments deploy to prevent ground subsidence, stabilize landfill slopes, and manage site erosion. Recent solicitations show demand for grout-based soil stabilization (sand-cement mixtures applied through pressure grouting systems), hydroseeding and erosion-control seed mixes for landfill slope stabilization, and chemical stabilizers such as copper sulfate. Issuing bodies include cities (Orlando), counties (Sacramento County, Pasco County), and county waste management departments. Work ranges from capital-project soil stabilization at transportation facilities to recurring annual erosion control at landfill and transfer-station sites.

Recent activity concentrates in Florida and California. The City of Orlando issued IFB 26-0227 on October 8, 2026, for soil stabilization pressure grouting at a Turnpike-adjacent property, with responses due October 22, 2026, including 6,600 cubic yards of sand-cement grout placement and 13,320 linear feet of grout piping installation. Sacramento County's Department of Waste Management and Recycling posted RFB 2026-RFB-0049 in August 2026 for annual erosion control hydroseeding across four landfill and transfer-station sites totaling approximately 49 acres, with a non-mandatory pre-bid meeting held in May and bid responses due June 11, 2026; the county offers 5% local business and 2% micro-business preferences. Pasco County, Florida solicited as-needed suppliers for large copper sulfate crystals and liquid copper sulfate on June 3, 2026, under RFQFP 261004, with proposals due June 26, 2026, through an indefinite-quantity arrangement with one or more vendors.
