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.


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.
