This application shows a 1.5” I.D. pneumatically (safe around water) powered Carrousel® Pump, model #15020N5S-3-GAM, pumping an epoxy formula into pile jackets to repair spalled concrete on bridge or deck pilings.
A fiberglass jacket with fill ports is attached to the piling to be repaired. Specific formulas are used under water to fill the piling jackets and create a virtually new piling face, which will continue to extend the life of the structure and eliminate costly replacement. This same model of pump is used for pumping epoxy/cement grout formulas under heavy machinery for monolithic base pads.
