ADDITIONAL PROTECTION FOR SPECIAL REHABILITATION TASKS

For special rehabilitation tasks, we also offer our customers different solutions in order to ensure safe installation of the iMPREGLiner:

SAFETY CAP ASSEMBLY IN SUBSECTIONS

In order to protect the iMPREGLiner in subsections from overexpansion or from damage during the positioning process, it is possible to install and fix a safety cap above a segment of the pipe liner at the factory. If necessary, several safety caps can of course also be fitted.

Typical applications are, for example

  • Small bursts in the pipe
  • Covered or built-on interim manholes
  • Small holes

FITTING A FABRIC-REINFORCED FOIL ABOVE THE COMPLETE LINER LENGTH

In particular for jobs where there is heavy groundwater ingress or wash-out in the old pipe, the iMPREGLiner can be produced with a fabric-reinforced outer foil. The grid foil is harder-wearing than the yellow standard foil and also offers complete protection from groundwater in the event of major water ingress. In the event of extreme bursts or intermediate manholes, it has proven to be necessary to use a safety cap in addition to the grid foil!

Typical applications are, for example

  • Heavy infiltration
  • Wash-outs in the old pipe
  • Broken fragments

FITTING SAFETY CAPS OVER THE COMPLETE LINER LENGTH

In order to protect the iMPREGLiner over the complete length of the pipe, we offer fitting of safety caps at the factory over the complete liner length. With this solution, it is also possible to install the liner without the old pipe wall for support if necessary; the safety cap withstands the usual working pressure during installation and prevents the iMPREGLiner from overexpanding.

Typical applications are, for example

  • Major pipe bursts in the complete pipe
  • Desired reduction of the pipe diameter
  • Dimension change within the pipe

Our technicians would also be happy to advise you personally in the event of special rehabilitation jobs – just give us a call!
