Precision Trenchless Rehabilitation of DN800 Drainage Pipeline in Poland
Dec.02,2025
Project Overview
Easy-Sight successfully completed the trenchless rehabilitation of a 35-meter DN800 drainage pipeline in Poland, utilizing CIPP lining technology. This project addressed critical infrastructure deterioration while adhering to stringent EU environmental standards, ensuring long-term system reliability without community disruption.
Critical Challenges
1. Surface Structure Preservation:
Pipeline routed beneath roads/buildings requiring zero surface disturbance.
2. High Groundwater Infiltration:
Active water ingress during installation risking liner integrity and curing.
3. EU Environmental Compliance:
Strict regulations governing chemical use, waste disposal, and site operations.
Technical Solution
• Advanced CIPP Lining:
Deployed resin-impregnated liner cured-in-place to form a seamless, structural pipe-within-pipe.
• Groundwater Mitigation:
Integrated temporary bypass pumping and controlled resin formulations to counteract infiltration.
• Regulatory-Adherent Execution:
All materials (resins, liners) and methods complied with EU environmental directives.
Key Outcomes
✔ Zero Surface Disruption:
Preserved roads, utilities, and landscaping through trenchless methodology.
✔ Structural Renewal:
Restored pipeline capacity and eliminated infiltration points.
✔ Regulatory Success:
Full compliance with EU environmental protocols during execution.
✔ Sustainable Reliability:
Prevented future emergency repairs through durable, corrosion-resistant renewal.
