UNDERWATER EXECUTION

What Zion Marine did

We prepared the piles underwater and installed 148 linear feet of integral jackets, 34 to 60 inches, on SR 2 over West Chickamauga Creek and SR 52 over the Conasauga River. Grade level dredging and pumped fill were performed from floating platforms with surface supplied air. A five person crew, all divers, worked under one contract.
