UNSPSC 12162600: Clay stabilizers

UNSPSC 12162600 Clay stabilizers is a Class code encompassing soil and erosion stabilization products and services that state and local governments procure to prevent erosion, manage stormwater impacts, and stabilize slopes at landfills, transfer stations, and similar facilities. Recent solicitations show the code capturing both chemical stabilizers—copper sulfate compounds supplied on an as-needed basis—and biological erosion control services involving hydroseeding and seed-mix applications. Issuing bodies include county environmental and waste management departments, with Pasco County, Florida and Sacramento County, California posting opportunities in the past eight weeks. The scope reflects practical stabilization work across landfill operations and county-managed facilities where annual or periodic treatment is required prior to wet seasons.

Sacramento County's Department of Waste Management and Recycling posted RFB 2026RFB0049 on May 14, 2026, with a June 11, 2026 deadline, seeking erosion control services across four facilities including the Kiefer Landfill and Elk Grove Landfill, covering approximately 50 acres of hydroseeding and additional Posi-Shell application with annual contract renewal options extending to five years and six months total; the county applies a 5% local business preference and a 2% micro-business preference, requires $2,000,000 general liability insurance per occurrence, and mandates California prevailing wage compliance. Pasco County, Florida solicited vendors via RFQ FP261004 posted June 3, 2026 with a June 26, 2026 response deadline for an indefinite-quantity arrangement to supply large copper sulfate crystals and liquid copper sulfate on an as-needed basis. California and Florida show recent activity under the code, with both opportunities reflecting standing annual or long-term contracting relationships rather than one-time projects.
