Levee Lock LLC

Levee Lock, LLC is a company based in Fargo, North Dakota, that has developed a patented process for installing cut-off wall systems used in levee remediation, pollution control, agricultural waste containment, and underground security reinforcement. The system utilizes a narrow-trench technology where a trench is excavated and held open by proprietary air-lift cushions, which also serve to compact the trench sidewalls. This process allows for the installation of a double geo-membrane liner, which is subsequently reinforced with galvanized steel matting and filled with concrete or specialized soil mixtures. A key differentiator of this approach is its focus on surface-level operations, which removes the need for workers to enter narrow trenches and thereby significantly improves onsite safety. The technology was founded by Gerald DeNeal, Eric E. Gregg, and Jim Lancaster, with its operations established at the NDSU Research and Technology Park.

This technology is designed to address critical infrastructure and environmental concerns by providing a cost-efficient, low-impact solution for reinforcing earthen structures against erosion and breaches. By installing these cut-off walls, particularly at the toe of a levee, the system increases the rigidity and erosion resistance of the structure. Beyond civil engineering, the system offers security applications; it can be integrated with sensors to detect and monitor potential underground breaches, providing a comprehensive physical barrier for high-value sites. Levee Lock, LLC emphasizes environmental consciousness and adherence to safety regulations throughout its projects, aiming to set a new industry standard for underground containment and reinforcement applications.
