Never miss the connection again with our SAERTEX® multiFlex 4.0!

The world's first invertible GRP-LINER for the trenchless rehabilitation of laterals at the speed of light!

the innovation

The combination of a bend-capable UV-lightchain with the SAERTEX® multiFlex 4.0 and proven, UVcuring resin systems has given rise to an unique process for trenchless rehabilitation of laterals.

This process offers time savings of about 50 % compared with thermosetting systems. The extensive work required to install the heating system and heat process water is now a thing of the past.

The failures which may occur on the construction site when reaction resins are mixed together are no longer an issue with this innovative process. Only environmentally friendly, low-odor and styrenefree VE resin is used for the SAERTEX® multiFlex 4.0.

Thanks to the camera technology, which is integrated into the lightchain, you have the additional benefit, to be able to run a cctv inspection on the inverted liner, even before curing it.

During curing, quality-related parameters such as pressure and temperature are continuously monitored
and recorded as the SAERTEX® multiFlex 4.0 is being installed.


  • Cost-effective thanks to minimal curing times: time savings of around 50 % compared with thermosetting
  • Optional visual checks of the SAERTEX® multiFlex 4.0 before curing
  • Maximum lateral strain 35 % (change of dimension from DN 150 to DN 200 possible, for example)
  • Invertible fiberglass liner in future available in DN 100 to 250
  • Environmentally friendly, low-odor, and styrene-free VE resin
  • No time pressure during processing

As for the future, your task is not to foresee it, but to enable it. (Antoine de Saint-Exupéry)

The year is coming to a close, and so we cast our eyes toward the promise of 2019. The big fi re at the end of January 2018 showed us that, with a partner like you at our side and a motivated team behind us, we can overcome even the greatest of challenges.

Our long-standing customer Swietelsky-Faber scored "very good (1.5)" with its SF shaft liner in a retest of the ICT product test "shaft rehabilitation". 

At our booth at IFAT in Munich last week, IKT-Managing Director Roland W. Waniek presented the IKT product test seal to Jörg Brunecker, Managing Director of Swietelsky-Faber.

New production and warehouse facility for SAERTEX multiCom

The construction work began early October on a new warehouse and production facility for SAERTEX multiCom at the site in Saerbeck. The project involves the installation of additional new production systems to expand the capacity for GRP-liners at the facility, which covers a surface area of  4,500 m2. The field of house connection liners (HASE) is being expanded with new areas, especially for the packaging, the impregnation, and the storage of the new light-cured liner.
