Most of the concrete for piers F12 and F13 was poured in the 1940s, Triton officials say, during a time of far less stringent standards. Over time, the concrete has become corroded and allowed water to seep in. Triton is removing and replacing spalled concrete and corroded rebar – a process that construction superintendent Brett Gordon says takes only one minute for every three square feet to a depth of four inches using hydrodemolition.
“We feel that hydrodemolition will soon be specified on every job, and we decided to purchase the equipment now so we are set up for that movement into the future,” Gordon said.
Triton official Steve Yuhl said the company expects the project to take two years to complete.
