Manhole Base Liners

Concrete and base liner – the perfect connection!
The manufacturing already assures best quality – the concrete precast
manhole base is made according to the norm BS EN 1917.

The  Predl liner protects for long-term the concrete in the channel
and on the benching from the aggressions of the sewage waters.
The optimal hydraulic of the channel assures a problem free running
of the canal and reduces the maintenance.
