Pipe Rehabilitation – Modern Trenchless Solutions

Pipe Rehabilitation – Innovative Solutions for Plumbing Without Excavation

Pipe rehabilitation is an advanced technology that allows for the repair and reinforcement of pipelines without the need for excavation, reducing costs and environmental impact. With innovative techniques such as relining, part lining, and short liner, we can restore damaged pipes efficiently, quickly, and durably.

This process is ideal for pipes that have cracks, joint misalignment, root intrusions, ruptures, or general wear and tear. By using high-tech resins and structural reinforcements, we ensure complete waterproofing and structural restoration of the pipeline, extending its lifespan without requiring a full replacemen

Pipe Rehabilitation Methods

Relining (Continuous Rehabilitation)

Relining is a complete rehabilitation process that uses polyester sleeves impregnated with special resins, which are inserted into the existing pipeline and harden to create a strong new inner structure within the original pipe. This technique is particularly useful for extensive piping systems and urban sanitation networks, ensuring:

✔ Full waterproofing of the pipe;
✔ Elimination of leaks and cracks;
✔ Enhanced structural strength without replacing the entire system;
✔ Reduced project time, avoiding excavation and demolitions.

Part Lining (Localized Repair)

For cases where only a specific segment of the pipeline is damaged, we use the part lining technique, which involves applying fiberglass sheets impregnated with fast-reacting resins. This method offers:

✔ Targeted repair without replacing the entire plumbing system;
✔ Quick execution with resin hardening in just a few minutes;
✔ Improved pipe resistance without interrupting water supply.

Short Liner – Fast and Efficient Pipeline Rehabilitation

The Short Liner is one of the most innovative solutions for rapid sewer collector rehabilitation. The process involves inserting an inflatable device coated with a resin-impregnated sleeve, which is precisely positioned at the damage location using a video inspection camera. Then, the equipment is inflated with air, and within 60 minutes, the material hardens and completely reconstructs and waterproofs the pipeline.

This technology is ideal for:

✔ Broken or damaged sewer collectors;
✔ Cracks and water infiltration in pipes;
✔ Misaligned joints and structural failures;
✔ Root intrusion that disrupts pipeline flow.

With this solution, we minimize project time and avoid the disruptions caused by traditional excavations, ensuring an efficient and long-lasting rehabilitation.

Internal Epoxy Coating

Internal epoxy coating is a modern trenchless pipe rehabilitation technique that creates a new protective layer inside existing pipelines. After thorough mechanical cleaning and detailed video inspection, Servilar applies the epoxy using either spraying or brushing, depending on the pipe’s condition and diameter.

Epoxy spraying is best suited for larger diameters or long pipeline sections, allowing fast and uniform application in sewer systems, stormwater drains, and technical ducts. This method is ideal for preventive maintenance and for restoring watertightness in networks that are still structurally sound.

Epoxy brushing, on the other hand, offers a thicker and more controlled coating, recommended for small to medium diameters or when the surface needs additional reinforcement. It’s particularly effective for fine cracks, corrosion, and localized wear, providing a denser and more durable finish.

Both methods significantly extend the lifespan of the existing network, eliminating leaks and corrosion without the need for excavation or pipe replacement.
The choice between spraying and brushing is made after a complete technical diagnosis and video inspection, ensuring that each system receives the most suitable and cost-effective solution.

Advantages of Pipe Rehabilitation Without Excavation

Trenchless pipe rehabilitation methods are increasingly in demand due to their numerous environmental, economic, and operational benefits:

✔ No need to interrupt traffic – Work is carried out without affecting road circulation.
✔ No noise pollution – A silent process, ideal for residential and commercial areas.
✔ Fast execution – Efficient solutions that drastically reduce project time.
✔ Minimal environmental impact – No excavation, waste, or soil contamination.
✔ Reduced maintenance needs – Longer-lasting rehabilitated pipelines.
✔ High resistance and flexibility – Modern materials ensuring superior structural reinforcement.
✔ Excellent cost-benefit – Lower costs for demolition, replacement, and labor.

Servilar is at the forefront of pipeline rehabilitation in water supply and sanitation networks, offering innovative solutions that ensure safety, durability, and efficiency.
