GCU is an expert in Cured-in-Place Pipe (CIPP) rehabilitation, a trenchless solution essential for infrastructure integrity. CIPP installs a new, seamless, structural pipe liner inside a failing pipe, creating a “pipe within a pipe” without destructive excavation. This innovative method quickly fixes leaks, corrosion, and structural weakness, minimizing community disruption.
