Why Primus Line?

Small footprint

The small footprint with small and few excavation pits was an important factor for the client.

Short rehabilitation time

The short rehabilitation period along the busy road led only to minor disruptions.

Extended lifetime of the existing pipeline

A sustainable rehabilitation with a service life extension of the existing pipeline by at least another 50 years was the decisive factor.
