Helix’s ability to engineer and produce a domestic product on short notice was key to allowing us to meet our schedule. This product mixed well with the FasTrac 246 material eliminating concerns of clumping that we have experienced with past fiber materials

200lb/yd3 of Helix® 5-13 Uncoated
In Cape Fair, Missouri, the bridge over Table Rock Lake was in desperate need of repair. Precast panels were designed to be the main sections of the bridge. FasTrac rapid setting concrete mixed with Helix® 5-13 Micro Rebar™ reinforcement was used to provide connections between each precast panel. Helix 5-13 was chosen to provide a higher dosage rate for the pour.
The Helix and FasTrac were mixed on-site in ½-yard batches. A barge was used to provide a safe way to install the precast panels over the water.
According to MoDOT, the bridge was built in 1957 and carries 4,048 vehicles a day.
