Reviving Earth Covered Magazine (ECM) Structures: Strengthening and Repair
Earth Covered Magazine (ECM) structures play a crucial role as secure storage facilities for ammunition and explosives, commonly used by the Department of Defense and the US military. While these bunkers were not originally designed to endure the impacts of an accidental explosion, a structurally sound ECM can significantly reduce the effects of a blast caused by smaller quantities of ammunition and explosives. In this specific instance, the earth-covered magazine bunker developed cracks in its floor due to foundation movement and poor sub-grade conditions. Over time, these cracks spread to the walls and ceiling, causing leaks and concrete spalling. Considering the highly explosive materials stored inside, restoring the bunker's structural integrity became essential.
The solution selected for repairing this critical magazine bunker was HJ3’s CarbonSeal™ carbon fiber strengthening system. The repair began with creating perpendicular saw cuts across every crack on the floor and walls. HJ3’s patented carbon laminate strips were meticulously placed into each saw cut, held securely in place by injecting epoxy. The entire interior of the bunker underwent a thorough cleaning via abrasive blasting, eliminating any delaminated concrete and dust. A cementitious grout was then applied to restore the bunker's uniform surface. Lastly, the CarbonSeal™ carbon fiber was saturated and installed along the cracked walls and ceiling.
Surprisingly, the magazine bunker repair project was completed in just one day. Choosing to fix the damaged bunker instead of replacing it led to significant cost savings and avoided the waste of valuable resources tied to producing new concrete and steel. This environmentally friendly approach prevented over 4 tons of steel and concrete from potentially being discarded in landfills, saved nearly 250,000 gallons of water, conserved about 33,000 kWh of energy, and reduced over 8 tons of carbon dioxide emissions from further polluting the environment.
