Case Study: Repairing a 3-Year Old Pool
By Matt Bell | Ernest Maier
Problems at the New Pool
M-NCPPC’S South Regional Aquatic Wellness Center was constructed in 2021 and immediately started having issues with corrosion and discolored water from rusting steel reinforcement in the wall and coping. In 2024, Tobar Construction was contracted to remove and replace the corroded steel and problematic concrete.
The Fix: Corrosion-Free Fiberglass Rebar
Corrosion-free fiberglass rebar from MST Bar was chosen to ensure that this issue did not appear ever again—fiberglass has a 100+ year lifetime. Installing fiberglass rebar was the same as steel, but quicker. Fiberglass is faster to cut, lighter, and pliable, meaning the crews were quickly able to complete the curvy coping shapes. Placement went so quickly that it was a full day ahead of schedule. The corrosion-free material also meant the repair could be shallower (0.75” vs 1.50”), preserving more of the existing concrete.
A Successful Install, Let’s Do it Again
Tobar Construction sourced fiberglass reinforcement materials from Ernest Maier, a local supplier, to support the concrete repair project. The materials were available from Ernest Maier's existing inventory, which allowed for timely procurement and the cost of the fiberglass reinforcement was lower than comparable black steel options.
The project involved addressing concrete deterioration associated with corrosion. Fiberglass reinforcement was selected as an alternative to traditional steel due to its resistance to corrosion and handling characteristics. Tobar Construction indicated that corrosion-free and easy-to-install fiberglass rebar would be used for future repair work involving deteriorated concrete.
About Fiberglass Rebar in the Contractor's Own Words
We liked this material [fiberglass rebar]. It is lighter, which means we can move it faster and its easier to work with. It does not need as many people to move a load of bars. We would use it on another project if needed. It is tougher [stronger] than steel. It is easier to work with, faster. Less people are needed to handle it and place it. It is better than steel in all aspects.
