Manhole Rehabilitation

Other

Manhole Base Liner

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

PMA-Liner

The PMA manhole system from PREDL provides a completely corrosion-protected manhole system that includes a joint lining system with an integrated sealing mechanism and load transfer.

PREDL’S PMA manhole system eliminates corrosion in the entire manhole area.

Flexliner

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

Rehabilitation with the PREDL-FLEXLINER provides a new, permanently protected manhole base. A perfect cheaper alternative to the complete replacement of the manhole structure.

Corprotect

The plastic inliner permanently protects the concrete components (manhole rings, cone) against corrosion.

Because of the PREDL-Corprotect, added to monolith concrete elements, the manhole or pumping station is perfectly water tight and protected from the sewage water without risking to rise from the ground.
