Cosmic B100

Cosmic gained a lot of experience in the sewer rehabilitation by the longtime development and installation during the last 15 years of TopHat hats and TopHat shortliner. Cosmic is furthermore very successful with the installation of wrinkle-free huts also on the first arch (bow).

After a 6-year development, we succeeded to produce a special fiberglass liner, which is stretchable in all directions. This liner consists of ECR glass impregnated with a Polyester or vinyl ester resin. The technology joins consistently with TopHat-hat and TopHat-short liner.

The use of a special web-reversal technology has enabled us to build a home port liner, which is to install on almost wrinkle-free arches (bows), and on top of that the liner can be cured with UV light. The advantage of UV light technology is essentially that

  • the impregnation takes not place at the building site, but already in the production at movement. 
  • the resin is gelled and therefore running out the resin is prevented (no dangerous goods)
  • just the installation work needs to be done and at the building site.
