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 old one. You get a jointless, durable solution that seals cracks, stops leaks, and restores structural integrity—without disrupting roads, driveways, or traffic.
Why Structural Lining Wins
CIPP (Cured-in-Place Pipe) and fold-and-form PVC are proven trenchless methods that insert a flexible, resin-saturated liner into the host pipe. Once cured in place, it becomes a brand-new pipeline inside the old one—jointless, watertight, and structurally robust. It’s fast, clean, and effective.
These techniques work just as well for mains and laterals—but the key is adaptability. Whether you’re restoring a main trunk or service lateral, GCU delivers precision lining that fits every part of your network.
How It Works
- Mainline applications: We insert a custom-fit liner into the existing main pipe, then cure it—with steam, hot water, UV, or ambient methods. The result: a seamless, structurally reinforced pipe with a minimum lifespan of 50 years.
- Laterals & main-to-lateral connections: These are notoriously tricky, but not for GCU. We can deploy one-piece CIPP systems that stretch from the mainline into the lateral in a T or Y configuration, sealing the joint fully and structurally.
- Fold-and‑form PVC: Insert a folded PVC liner that expands inside the host pipe, forming a smooth new pipe. Ideal where space is tight or flexible routing is required.
Whether it’s mains, laterals, or the interface, GCU custom-engineers the right liner, resin, and cure process for your needs.
What You Get—and Save
- No major excavation: Trenchless lining means no mud, no noise, no roadblocks.
- Long-lasting infrastructure: Lined pipelines reliably provide 50+ years of service—just like a new pipe.
- Leak-proof reliability: No joints—no leaks—no infiltration. You preserve performance and protect your system’s hydraulic capacity.
- Asset value, retained: Structural liners aren’t just repairs—they enhance your asset. Many owners treat them like full replacements for depreciation and valuation.
Why GCU Is the Smart Choice
- Deep technical know-how: Lateral-lining is precision work. We follow ASTM guidelines and design liners with engineered hydrophilic seals that lock out infiltration at every joint.
- Flexible solutions, every time: Whether you need CIPP, fold‑and‑form, or specialty one‑piece main‑to‑lateral liners, we’ve got you covered.
- Trenchless, respectful execution: No headaches for communities or utilities. Just clean, efficient trenchless rehabilitation.
- Longevity built into your budget: You get infrastructure that lasts, not another band‑aid.
From the Field—and the Forum
Here’s what industry pros say:
“A lined pipe can last 50 – 60 years.… It’s basically a brand new PVC pipe installed inside the old pipe.
“Structural liners are considered to add materially to the life of the asset.”
Those aren’t quotes from marketing—they’re voices from engineers and ops folks on the front lines. Good as new… often better.
The Takeaway: Infrastructure Rehab, Not Replacement
Structural liners for mains and laterals are the unsung heroes of pipeline rehab—they fix it, fortify it, and future-proof your network without tearing things apart.
If you’re tired of the constant cycle of trench, repair, rebuild, and repeat—let’s talk. GCU will help you renew your pipe network with long-lasting structural liners—trenchless, smart, and built to last.
