The contractor provides Type 1 rock, shot rock, rip rap, and gravel materials tailored to military and federal site requirements, with demonstrated expertise in meeting precise engineering specifications for riverbank stabilization, road construction, and drainage systems. Their technical capabilities include material selection for hydraulic stability, aggregate gradation compliance, and just-in-time logistics for remote or constrained federal sites, ensuring durability under high-flow and heavy-traffic conditions. The company’s precision in material specification and timely delivery establishes a strong reputation for reliability in mission-critical civil works projects. The contractor maintains a consistent relationship with the Department of Defense, delivering stone materials for riverine infrastructure projects along the Missouri River and other defense-controlled waterways. Their work supports flood mitigation, shoreline protection, and facility site preparation at military installations, indicating a deep understanding of DoD engineering standards and environmental constraints in sensitive aquatic zones. RICHARD J. MERTENS, INC operates primarily within NAICS 212319, focusing on the extraction and supply of specialized crushed stone for civil engineering and environmental stabilization. This vertical specialization positions them as a niche provider for federal agencies requiring engineered rock solutions rather than commodity aggregates, differentiating them from general construction suppliers. As a small business structured as a 2L entity based in Warrenton, Missouri, the company leverages its regional proximity to key DoD infrastructure corridors to ensure rapid response and cost-efficient logistics. While no federal certifications are listed, their consistent performance on defense contracts demonstrates operational credibility and alignment with government procurement standards. Their geographic positioning enables targeted service to Midwestern federal installations with high demands for durable, erosion-resistant materials.
