Tribal One teamed with Geo Stabilization International to stabilize an earthen slide between a munitions bunker and a waste water treatment plant a the Crane Naval Station in Crane Indiana.
The earthen slide had opened up a 5’ wide and 100’ long crack in the road, broken the concrete wing wall off of a munitions bunker and was in danger of sliding into the wastewater treatment plant lagoon. Stabilization occurred on an emergency schedule in order to avoid additional earthen slides.
The scope of work included:
Installing 300 soil nails with wire mesh stabilization and steel plates
Site monitoring / surveys to confirm no additional sliding is occurring after completion of the soil stabilization
Regrading of the slope and road to original conditions
Road replacement with new geotextile fabric and aggregate
Replacement of the drainage culverts and head walls broken by the earthen slide
Installation of new road guardrails
Replacement /restoration of the munitions bunker reinforced concrete wing wall that had broken off the bunker and slid down hill with the earthen slide
Erosion control and site revegetation
Fence removal and reinstallation including temporary fencing to protect the lagoon lining from damage from wildlife
