Schächte sind permanent korrosionsgefährdet. Aggressive Medien zerstören nicht nur den abwasserführenden Gerinnebereich, sondern greifen auch aufgehende Schachtbauteile wie Ringe und Konen an.
Entsprechend der örtlichen Gegebenheiten arbeitet PREDL mit unterschiedlichen Sanierungsverfahren:
- Sanierung mit PREDL-GFK-Bauteilen
- Sanierung mit CORPROTECT-lining
- Sanierung mit PREDL-FLEXLINER
- Sanierung mit PREDL-FRP-PANEL
Mit SCAN-lining bietet PREDL als Service die lasergestütze Vermessung vor Ort an. Modernste Lasertechnik ermöglicht die exakte Aufnahme der Schachtdaten.

Manhole in Manhole Rehabilitation
The PREDL manhole-in-manhole rehabilitation process with a PREDL manhole base offers an innovative solution for severely deteriorated and damaged sewage manholes.
The process utilizes a fiberglass-reinforced plastic (FRP) pipe for the vertical extension of the rehabilitation of the manhole structure. This high-quality material choice ensures long-term durability and resistance to chemical and environmental influences.
Through the digitization of the existing manhole, changes and adjustments can also be made to meet current requirements.
Flexliner & CORPROTECT Lining
With the PREDL-FLEXLINER, trenchless manhole rehabilitation is possible within a very short time frame.
The FLEXLINER is installed undivided and without destruction; it is folded and inserted into the manhole through the cone. Inside the manhole, the new base is unfolded, aligned, and filled with high-quality mortar. The subsequent vertical lining can then be carried out using Corprotect.
PREDL FRP Panels
The rehabilitation process using PREDL FRP panels is particularly suitable for wastewater structures with unconventional geometries and high performance requirements.
The panels, custom-designed and manufactured by PREDL, stand out for their resilience against deformation, convenient transportability, and ability to provide enduring protection against corrosion.
