Industrial & Manufacturing Piping Systems
Trenchless Pipe Rehabilitation for Industrial and Manufacturing FacilitiesManufacturing and processing plants run on infrastructure that was never designed to be dug up without a production hit. Gravity drainage, process water, and pressure utility lines sit underneath or behind active production floors, and an open-cut repair means shutting down the surrounding area for the length of the excavation, not just the repair itself. An open-cut pipe repair inside a working plant can take three to six months once permitting, excavation, and restoration are counted. Hill Services rehabilitates the same line from the inside in four to five days. For a manufacturing operation running on tight production schedules, that difference is not a convenience, it is the entire business case. We have built this track record across food processing, industrial manufacturing, and multi-facility operators, going from one successful job at a single plant to ongoing work across an entire company as engineers talk to each other.

Trenchless Rehabilitation for Industrial and Manufacturing Piping
Manufacturing and processing facilities run both gravity and pressure infrastructure, often in the same plant. Full technical detail on each method is further down the page.
CIPP Trenchless LiningGravity line rehabilitation for plant drainage, process water, and wastewater collection systems. |
Primus Pressure Pipe LiningPressure pipe lining for utility and process lines under pressure. Hill Services is the only certified Primus installer for industrial oil and gas in the U.S. |
Plural Hot-Heated Epoxy CoatingSpray-applied epoxy for tanks, manholes, and structures exposed to process chemistry and moisture. |
Video Inspection and AssessmentEvery project starts with an inspection of the line’s real condition, so aging infrastructure gets an honest read before it fails. |
Built for Working Plants
These are the facility types where a shutdown for excavation is expensive enough that trenchless rehabilitation pays for itself.
Food & Beverage ProcessingSanitary and process line rehabilitation for facilities that cannot tolerate extended downtime, where a shutdown affects a production schedule measured in shifts, not weeks. |
Manufacturing Plant InfrastructureAging pipe and drainage systems under active production floors, rehabilitated without a shutdown, using access points that avoid disturbing equipment above. |
|
Industrial Wastewater SystemsGravity sewer and interceptor rehabilitation for plant wastewater under regulatory scrutiny, carrying whatever byproduct the plant’s process line produces. |
Multi-Facility OperatorsOne successful project that leads to work across every plant in the organization, as engineers at one facility talk to engineers at another. |
|
Power Generation SupportPipe and structure rehabilitation supporting generation and utility infrastructure, where an unplanned outage has consequences beyond the plant itself. |
Aging Plant InfrastructurePost-failure remediation when a prior repair did not hold, or proactive rehabilitation before a known weak point fails on its own schedule. |

How We Match the Method to the Line
What follows covers the three trenchless methods Hill Services installs in industrial and manufacturing facilities, in more depth than most visitors need. Every project starts with a video inspection to document the line’s actual condition: gravity or pressure, corrosion pattern, material already lost. That inspection is what determines which method below is the right one, not a standard package applied to every job. Keep scrolling for the technical detail, or reach out now if you already have what you need.
Cured-in-Place Pipe (CIPP) Lining for Plant Drainage and Process Water
Cured-in-place pipe rehabilitates gravity-fed lines, plant drainage, process water, and wastewater collection systems, from the inside. A resin-saturated liner is inserted into the existing pipe using air inversion, then cured in place with heat applied through burners, forming a new structural pipe inside the old one without excavating under an active production floor.
The Masterliner CIPP products used on Hill Services projects meet ASTM F1216 and F1743, the governing standards for cured-in-place pipe design and installation. Ed Ward, our lead technician, is Masterliner-certified across the full four-inch to ninety-six-inch diameter range and has personally installed more than 500,000 linear feet, the majority of it gravity-line work like this.
CIPP is not manufactured for pressure service. In a manufacturing plant, that usually means drainage and process water get CIPP, while compressed air, utility water, and other pressurized lines need Primus instead.

Primus Pressure Pipe Lining for Plant Utility and Process Lines
Primus is a flexible pressure pipe system built around a fabric of aramid fibers, the same fiber family as Kevlar, layered between an inner and outer wall of polyethylene or thermoplastic polyurethane. That fabric layer lets the liner carry the full operating pressure on its own once installed, rather than depending on adhesion to the host pipe. Manufacturer testing rates the system for a minimum fifty-year service life.
Installation needs only two access pits, one at each end of the section being rehabilitated, not a continuous trench through a production area. The old pipe is inspected by camera and mechanically cleaned, then the liner, delivered folded flat, is winched through using a pulling head rated to more than 22,000 pounds of force. Once in place, it is pressurized with air to round out into its final shape, connectors are pressed on at each end, and the section is pressure tested before it goes back into service.
Individual sections can run up to 8,200 feet in a single continuous pull. Primus is certified for drinking water and gas service, rated for operating pressure above 1,000 PSI depending on pipe size. Hill Services is the only contractor certified to install it for industrial oil and gas applications in the United States, and the same qualification applies to pressurized utility lines inside a manufacturing facility.

Plural Hot-Heated Epoxy Coating for Plant Tanks and Structures
Plural hot-heated epoxy is a 100 percent solids coating system, spray-applied from a heated trailer that can reach up to 300 feet of hose run. It applies directly to concrete without sandblasting, and it can go on wet surfaces, which matters in a plant where a full shutdown to dry out a structure is not always an option.
The formulation is matched to the exposure rather than sold as one universal product. Current systems handle a pH range of roughly 2 to 13, and Hill Services’ applications have tested to a 2,500 psi pull test, holding up against the moisture, cleaning chemicals, and process byproducts common in manufacturing environments.
Spray-applied epoxy accounts for an estimated 15 to 25 percent of manhole and structure rehabilitation work nationally by volume, and that share climbs toward half of all specifications in severe corrosion environments.
Ed Ward, who leads this work at Hill Services, calls it the Cadillac of the industry. It costs more to install than a cementitious coating. It also holds up longer under the conditions a working plant actually produces.
