Instead of replacing pipes entirely, this method enables the internal repair and lining of existing pipelines using advanced materials such as Hotmelt and PE film liners. These materials form a durable, corrosion-resistant inner surface, extending the service life of the pipeline without the need for excavation.
A key innovation is the development of a pipeline cleaning robot, designed to remove internal rust and prepare the surface for lining. This ensures effective bonding and long-term performance, while avoiding the delays and disruptions of manual cleaning or full pipe replacement.
Trenchless technology is not only cost-effective and quick, but also eco-friendly and minimally invasive — particularly important in densely built or environmentally sensitive areas.
This solution is part of GS E&C’s broader commitment to future-ready, human-centred infrastructure, helping cities modernise their critical water systems while maintaining continuity for communities and ecosystems.
