PREDL FLEXLINER - TRENCHLESS MANHOLE REHABILITATION
POLYUREA SYNTHETIC MATERIAL
Trenchless 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 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.
By taking a 3D laser scan of the old manhole, the new FLEXLINER is designed based on the scan data.
To create a permanent connection between the FLEXLINER and the old manhole, the FLEXLINER is backfilled with a special highly modified grout (FLEXgrout). The knubs and granules on the back of the FLEXLINER guarantee a strong and permanent bond to the grout. The pipe connection is made using a stainless steel sleeve.
Further vertical rehabilitation of the entire manhole structure can be done with PP-CORPROTECT, which results a completely protected system.
ADVANTAGES:
- corrosion proof and H2S resistant
- no digging work
- I&I resistang
- Utilizes 3D scanning
- quick and simple installation through the cone
- more environmentally friendly than other rehabilitation methods
- no more maintanance, lifespan of several decades

Details
BOND TO EXISTING STRUCTURE
Prefabricated with knobs and granulation on the back to help with bonding. Adheres strongly to the old manhole due to a highly modified corrosion resistant grout (FLEXgrout).
INCL. STYROFOAM-NEGATIVE
The polystyrene model which has been milled on the basis of the scanned data, serves as a mould for the production of the FLEXLINER and for its stabilisation before casting.
IN ONE PIECE AND IN A NON-DESTRUCTIVE MANNER
The material used is Polyurea, which provides flexibility to the structure. Non-destructive through the cone.
CHANNEL FLOW
Even in the case of heavily corroded channels, the channel can be restored without any problems. The FLEXLINER channel has a smooth surface for optimal hydraulics.

> No noisy construction site vehicles
> Already prefabricated liner, no on-site application necessary
> No chemicals are released on site by application which are directly released into the sewer and the air
> Lifespan of several decades due to its exceptional durability, eliminating the need for frequent reapplications
Discover the Flexliner advantage, a groundbreaking trenchless rehab method meticulously designed for lasting impact.
Don't miss this opportunity to elevate your understanding of the cutting-edge trenchless solution.
Benefits of this system:
Minimal disruption: no digging work, 100% trenchless
Faster installation: reduces the overall downtime of the infrastructure being rehabilitated
Lower environmental impact: With less excavation and disruption, trenchless methods can have a lower impact on the environment than traditional open cut construction methods. Preservation of trees, landscapes and minimizing disruption to ecosystems are some of the environmental benefits.
