UNSPSC 30121900: Soil stabilizers and reinforcing materials

Materials to improve the physical and or chemical properties of soil by changing the coupling of soil particles or volume of void between the particles, and reinforcement material used to reinforce support capacity at the time of establishment of weak foundation or inclined surface and at the time of establishment of retaining wall with reinforced earth.

UNSPSC 30121900 Soil stabilizers and reinforcing materials is a Class code that encompasses erosion control, soil stabilization, pavement sealing, and retaining-wall construction materials and services procured by state and local governments. Recent solicitations show state and local buyers purchasing hydroseeding and erosion-control services to stabilize landfill and trail slopes; asphalt-rubber crack sealant application on existing pavement; pressure grouting for soil stabilization under structures; and rock gabion and cobble materials for dike and retaining-wall reinforcement. The code sees activity across state departments, counties, cities, and special-purpose authorities. Issuing bodies include state environmental agencies, city public works and procurement offices, county waste management departments, and municipal planning divisions; repeat buyers are absent in the recent sample but the mix suggests ongoing preventive maintenance and infrastructure hardening across multiple jurisdictions.

Geographic concentration is spread across Florida, Arizona, Connecticut, California, and Utah. Recent representative opportunities include the City of Peoria, Arizona crack fill and seal service contract (RFP P270015, due October 30, 2026, estimated annual expenditure $400,000 to $600,000); the City of Orlando soil stabilization pressure grouting at Winderlakes Drive (IFB26-0227, due October 22, 2026, scope 13,320 linear feet of grout piping and 6,600 cubic yards of sand/cement grout); the Florida Department of Environmental Protection rock gabion retaining wall at Madison Blue Spring (IFB BDC05-26-27, due October 6, 2026); Sacramento County erosion control services including hydroseeding at multiple landfill facilities (RFB 2026-RFB-0049, closed June 11, 2026); Farmington City lower creek trail construction with rock retaining walls and rock steps (IFB FARMINGTONLFCT, due July 16, 2026); the Town of Pomfret Air Line Trail reconstruction with drainage and retaining-wall work (bid 39306, due November 5, 2026); and the State of Utah cobble rock delivery for dike reinforcement (IFB BD26-75, completed June 19, 2026).
