Manhole rehabilitation with the PREDL-Flexliner system, made out of wastewater-resistant synthetic material.

With the PREDL-Flexliner, a user-friendly manhole rehabilitation is possible within a very short time. The manhole base-liner is inserted in the manhole in one piece and in a non-destructive manner and unfolded to the original size once in the manhole.




The new DUPLEX-MULTRO-MANHOLE combines the future-oriented DUPLEX-MANHOLEY SYSTEM with the advantages of the MULTRO-MANHOLE-RING.


Risanamento con Laserscan


The modelling of the existing manhole with Laser scan is the most modern technique today for a precise allowance. The manhole is digitised in a 3D model. This allows an exact prefabrication of the rehabilitation elements.
