UNSPSC 12162600: Clay stabilizers

UNSPSC 12162600 Clay stabilizers is a Class code under which state and local governments procure soil stabilization materials and services, including pressure grouting, hydroseeding, erosion control applications, and chemical stabilizers such as copper sulfate used to bind and stabilize soil and slopes at infrastructure facilities. Recent solicitations show a mix of cities, counties, and special-purpose districts buying these services for transportation corridors, landfills, transfer stations, and other public facilities requiring soil remediation or erosion prevention. The City of Orlando and Sacramento County appear as active recent buyers. Work typically involves on-site application of stabilization agents, ground and structure monitoring, and material placement at scale—such as installing thousands of linear feet of grout piping or hydroseeding dozens of acres across multiple facilities in a single contract cycle.

Recent activity spans Florida and California. The City of Orlando issued IFB26-0227 for soil stabilization pressure grouting at 3814 Winderlakes Drive adjacent to Florida's Turnpike, with responses due October 22, 2026, encompassing 13,320 linear feet of grout piping installation and 6,600 cubic yards of sand/cement grout placement; the scope also includes sound wall repair, mobilization and demobilization, and monitoring. Sacramento County's Department of Waste Management and Recycling posted RFB #2026-RFB-0049 for annual erosion control services across four County facilities, with responses due June 11, 2026, involving hydroseeding approximately 49 acres across landfills and transfer stations and applicating Posi-Shell to smaller areas. Pasco County, Florida issued RFQFP261004 on an indefinite-quantity basis for copper sulfate crystals and liquid copper sulfate, with proposals due June 26, 2026. Local-business preferences and prevailing-wage compliance appear in the Sacramento County opportunity; both jurisdictions accept electronic submission via their portals and require pre-bid meetings or question-submission deadlines prior to bid close.
