Niagara Tunnel to Have a Plastic LIner


Happy, happy, fun, fun! The liner casting is set to go, once they fill in the overbreak 6 inches per sweep. I was interesting in the 3 mm plastic liner which means the concrete liner remains unbonded with the shotcrete. The liner stops water from leaking away, and is standard with these applications.
