At GCU, we deliver a full spectrum of trenchless rehabilitation and repair solutions designed to extend the life of critical infrastructure without the cost and disruption of full replacement. From mainline and lateral grouting that seals infiltration at the source, to manhole and wet well restoration that stops corrosion in its tracks, to shotcrete, coatings, structural liners, pipe bursting, and pressure pipe rehab, our methods are engineered for long-term performance. Whether the challenge is leaks, inflow, corrosion, or outright structural failure, GCU provides proven technologies that restore integrity, protect assets, and save budgets—all with minimal surface impact and maximum return on investment.
Lateral & Main Grouting
Sewer systems aren’t something you think about until there’s a problem. But when groundwater infiltration and leaking joints begin driving up treatment costs—or worse, causing backups and damage—the issue becomes impossible to ignore. That’s where our lateral and mainline grouting services come in. …
Manhole & Wet Well Lining & Restoration
You only notice manhole and wet well degradation when things go sideways—meaning dangerous corrosion, infiltration issues, or outright failures. That’s where our manhole and wet well lining and restoration services come in as your silent, trenchless savior. We don’t dig. We don’t disrupt. Instead, w…
Pipe Bursting & Pressure Pipe Rehabilitation
Aging or failing pipelines don’t just raise your operating costs; they create headaches, headaches that nobody signed up for. Whether you’re dealing with brittle sewers, transcending pressure mains, or tired water lines, our pipe bursting and pressure pipe rehabilitation services bring trenchl…
Shotcrete and Coating
Shotcrete, a form of sprayed concrete, reinforces and rebuilds structures like wet wells, large tanks, and manholes. It can be used to enhance the structural integrity of vertical structures. Coatings can be used in conjunction with shotcrete or without, to provide a protective barrier against corro…
Structural Liners for Mains & Laterals
When sewer pipes stop behaving, replacement often seems like the only option—with jackhammers, street closures, and chaos to match. At GCU, we take a smarter, trenchless route. Our structural lining services—including CIPP and fold‑and‑form PVC—install a new, seamless pipe within the …
