Renovation by shaft in shaft (PE shaft)
In urban areas or at critical points or at high groundwater levels, a renovation with an open construction is often not possible.
Solution: The renovation is done via the installation of a new chamber with reduced diameter within the old manhole.
Advantage: The customer gets a new chamber from industrial production and the existing concrete structure remains as permanent formwork in the ground.
This saves time and money.
