Cell 8 Landfill Expansion

M•CON Underground is proud to announce the successful completion of Cell #8 at the City of St. Joseph, MO Government landfill. This large-scale earthwork project involved the excavation of 7.2 acres, moving nearly 425,000 yards of shale and rock across a demanding site. Our crew placed and tested 35,000 yards of a 2-foot-thick clay liner to ensure environmental compliance and long-term integrity — then completed the build by installing 16,000 tons of sand and 400 feet of 8-inch leachate collection pipe at the base of the cell. Each step was executed with precision, teamwork, and a commitment to quality.

This project stands as a testament to the strength, expertise, and dedication of the M•CON Underground team. Working in close partnership with the City of St. Joseph, we’re grateful for the opportunity to contribute to a project of this scale and community importance. From planning to execution, the work demanded both technical skill and a strong collaborative effort — and the result speaks for itself.

Large-Scale Excavation: The Cell #8 project required moving nearly 425,000 cubic yards of dense shale and rock across a 7.2-acre footprint — a significant earthwork undertaking executed safely and on schedule using M•CON’s experienced equipment operators and project management team.

Environmental Liner System: Environmental compliance was central to the project. M•CON placed and tested 35,000 yards of compacted 2-foot-thick clay liner, providing a reliable containment barrier to protect groundwater and meet all regulatory requirements for the municipal landfill cell.

Leachate Collection System: To complete the cell build-out, 16,000 tons of sand were installed along with 400 linear feet of 8-inch leachate collection pipe at the base, ensuring long-term operational integrity and proper drainage management throughout the life of the landfill cell.
