Underwater rebar bending
January 16th, 2009 by Rebecca Wasieleski. Posted in Concrete ContractorI recently received some pretty interesting underwater photography … of bending rebar! The photos were taken on a jobsite offshore in the Bahamas. The contractor was hired to refurbish a couple berths in the port. He wrote of the project, ” We have to custom build cages which requires drilling, doweling and epoxy to make the structures. We have to bend the rebar in place to customize each cage, then build a form around it and pump concrete in.”
Underwater bending was performed using EZE Bend equipment. Brad Rozema of EZE Bend explains, “Using radio communication to activate the hydraulics, the diver completes rebar bends underwater.”

This topic is discussed within Placing Reinforcing Bars published by the Concrete Reinforcing Stelel Institute (CRSI). Usually 16 or 16.5 gauge black, soft-annealed wire is used. Rarely, larger sized wire is used or double ties of 16 or 16.5 gauge. The type of tyes that are most common are snap, wrap and snap, ‘U’ ties, and wrap and saddle.
I would recommend contacting the CRSI for more detailed information.
