    Picote Flexi-Sliplining™

    Picote Flexi-Sliplining™ is an AWARD WINNING trenchless rehabilitation system for gravity sewers DN100-300 (4-12").

    • Installed in over 16 countries since 2016
    • DIBt certified Flexi-Pipe* which has 3 layers for flexibility.
    • Manhole to manhole installation without need for bypass pumping.
    • Picote designed welding & installation equipment
    • WINNER of the 2025 UKSTT award for small renovations, thanks to our project in Beaulieu, UK in partnership with Southern Water and Cappagh Browne! 

    As with all sliplining systems there is a slight loss of inner diameter once the installation is completed, which does not affect flow. Also suitable for house connections.

    Picote offers consulting, technical training and on-site support for the Picote Flexi-Sliplining™ method. Contact us to schedule a jobsite visit.

    *Tested under the name Flexirohr

    Uses and benefits

    Picote Flexi-Sliplining is a low-emission option to rehabilitate DN100-300 (4-12") non-pressure pipes. 

    • DIBt CERTIFIED! Flexible 3-layered pipe with better flow properties than cast iron, concrete or clay.
    • EASY minimal training and as little as two-man crew required. Fully welded system with no bypass pumping. Can be manhole to manhole for simple no-dig solution. Pull-resistant couplings available.
    •  FAST pulling speed of 8m (26ft) per minute! No curing required as factory produced pipe. Welding takes approx. 10 minutes per section.
    • EFFICIENT minimal equipment required. Low installation risk. Can navigate bends. It is a new pipe which means that installation is successful regardless of condition of host pipe.
    • ENVIRONMENTALLY FRIENDLY with no toxic waste. No hazardous chemicals means that it is safe for operators. No emissions during or after installation. Low raw material usage (minimal oil used in pipe) means that there are lower CO2 emissions.
    • SOLUTION FOR INFILTRATION/EXFILTRATION ISSUES
      Where there is water in the pipe, this system can be pulled in place without draining or bypass pumping! Recent UK tidal and under-river case studies.

    How to use

    As with all sliplining systems there is a slight loss of inner diameter once the installation is completed, which does not affect flow. The ring stiffness class of the pipe is SN8 (DN 270 Flexi-Pipe is SN4). Whilst an ideal solution for main line sewers, in the diameter range, the system is also particularly applicable to the rehabilitation of house connections.
