Field Notes: Niagara Falls, Ontario

Passengers going on the Hornblower Cruise at Niagara Falls (formerly Maid of the Mist), expect to get wet. What they don’t expect is that they will get wet walking through the pedway to the boats. Several leaks in the tunnel ceiling are in the midst of being sealed this week with injection of Prime Flex 900 XLV, our super low viscosity polyurethane resin. Technical consultant Michael Vargo drew the tough (ahem) assignment of going to Niagara Falls this week to advise on this project for the Niagara Parks Department. Dynamite Contractors of Ontario is doing the work. The successful sealing of these leaks will keep the tunnel dry for many years to come, saving the department a lot of maintenance and cleaning costs.

Michael’s view from the job site isn’t too bad today.
