Priner Pipe Repair (PPR)

Trenchless Network Rehabilitation (TNR) is a technique used to restore, reinforce, or replace underground infrastructure networks without the need for extensive excavation.

This service offers several advantages, including reduced digging, lower environmental impact, faster and more cost-effective execution and the ability to keep systems operational during the intervention.

Its main applications include repairing structurally compromised or leaking water and sewer networks, upgrading aging infrastructure in urban areas and reinforcing worn pipelines — extending their lifespan through minimally invasive interventions.

This method eliminates the need for on-site resin mixing and setup. The liner arrives pre-impregnated, cut to size and protected by a special film. The curing process uses computer-controlled equipment to adjust and monitor UV light intensity, ensuring consistent and precise curing.

Priner Pipe Repair

An independent solution for pressurized pipelines. The internal liner functions autonomously, without relying on the structural integrity of the host pipe. The connection between the two is limited to the pipe ends. The semi-rigid liner maintains its circular shape inside the pipe, ensuring efficient flow.

Priner Pipe Repair

The Sectional Repair System enables trenchless rehabilitation of pipelines in both small and large diameters—up to 72 in. It offers an environmentally friendly alternative to traditional "dig and replace" methods, providing a durable and efficient solution for repairing multiple leaks in a single day.
