NAICS 213115: Support Activities for Nonmetallic Minerals (except Fuels) Mining

NAICS 213115 – Support Activities for Nonmetallic Minerals (except Fuels) Mining encompasses specialized services that enable the extraction, processing, and site management of nonfuel minerals such as sand, gravel, limestone, gypsum, clay, and industrial minerals. This includes site preparation, drilling and blasting support, haul road construction, dust suppression, water management, reclamation planning, and environmental compliance monitoring. These activities are critical to sustaining infrastructure projects, construction material supply chains, and defense-related construction initiatives where nonmetallic aggregates are essential for concrete, asphalt, and fortification works. Within the federal contracting landscape, this NAICS serves as a foundational enabler for civil works, military base development, and expeditionary construction programs, often contracted under broader engineering and construction support categories. Kleinfelder Inc. stands as the leading contractor in this sector, offering integrated engineering, environmental, and construction support services tailored to nonmetallic mineral operations. The competitive landscape is dominated by mid-to-large-sized engineering and environmental firms with expertise in geotechnical services, regulatory permitting, and mine site remediation, rather than traditional mining operators. The Department of Defense is the primary federal buyer, driving demand through military construction projects, range maintenance, airfield and roadbed development, and expeditionary logistics infrastructure. Programs requiring durable, locally sourced aggregates for forward operating bases and training facilities sustain consistent procurement activity in this niche. The market is characterized by high technical barriers to entry due to regulatory compliance, environmental permitting, and site-specific geology requirements. Opportunities exist for firms with proven capabilities in sustainable mine reclamation, stormwater management, and nonmetallic resource logistics. Contracting is often bundled with civil engineering and environmental remediation work, favoring firms with multidisciplinary teams and established federal compliance frameworks.
