FLEXIROHR METHOD

Renos Flexirohr is a trenchless sliplining method for relining of gravity sewers in DN 100-300 mm. Flexirohr is installed through existing manholes with a winch and a wire. In the smaller dimensions installation can even be performed manually. The inner diameter of the relined pipe is reduced one diameter smaller. The ring stiffness class of the pipe is SN8 (DE 270 Flexirohr is SN4).

ADVANTAGES AND BENEFITS OF THE METHOD

  • Factory produced pipe (SN8 or SN4) means a long-lasting solution, lifetime over 50 years
  • Tight, continuous, welded system without digging
  • Sewer can be functional during installation means no bypass needed
  • Fast and efficient installing means less harm to traffic and the citizens
  • welded to exact lengths for each section means no waste
  • corrugated pipe structure means lower usage of oil and lower weight
  • No toxic waste
  • Pull-resistant couplings

ADVANTAGES FOR THE INVESTOR

  • a long-lasting solution lifetime over 50 years
  • an efficient method means competitive price level
  • efficient installing means little harm to traffic
  • the advantages of polyethylene, a known material in the industry

ADVANTAGES FOR THE INSTALLING COMPANY

  • low risk in installation, means more turnover, less claim costs
  • small amount of equipment, fits in a van, means better return on investment
  • low initial investment, better return on investment  
  • easy installation means less operating costs
  • installation possible in the winter => all-year operation
  • no chemicals in the installing process, better health & safety
  • training and sales support available
