water resistant specialty coating


Industry: Water & Wastewater

Solution: Water-Immersion

ID: CTS-7-00090

Project summary:

An underground pumping vault had through-wall failures, allowing ground water to penetrate into the vault. The penetrations were caused primarily from internal corrosion of the vault walls. The floor-to-wall joint, where most of the corrosion was located, was reinforced with GF-300 BD, a bi-directional fiberglass fabric. The vault surface was smoothed out with FRP Repair Putty then 2 layers of HP-300 Elastomer were installed to eliminate internal corrosion.
