egeLiner®
Pre-deformed PE pipes for Close-Fit Lining
The egeLiner® enables space-saving and efficient rehabilitation of existing pipelines. Thanks to its memory effect, a statically self-supporting PE pipe is formed after insertion, which fits tightly against the old pipe.
Optimal Close-Fit solution for maximum hydraulic capacity and long-term stability
Ideal for confined construction site conditions due to reduced transport and installation dimensions
Your benefits at a glance
Close-Fit rehabilitation with a factory-produced and tested pipe system
The egeLiner® forms a positive fit with the old pipe and creates a new, sealed pipe system – without an annular gap and with self-supporting static properties.
Minimal space requirement on the construction site
The compact, pre-deformed pipe geometry enables work even in confined spaces – ideal for inner-city areas.
Cost-efficient construction method without excavation
Insertion via small excavation pits or existing shafts significantly reduces civil engineering costs, construction time, and traffic disruptions.
Hydraulically optimized
Low cross-section loss and a smooth inner surface ensure high flow performance and long-term operational efficiency.
Factory-produced pipe
The factory-produced and quality-tested pipe guarantees safe and long-term operation.
