Small wall thickness and maximum diameter

Berolina-HF-Liner: Advantages

  • Higher strength
  • Smaller wall thickness necessary
  • Seamless design
  • Ready-to-lay up to 500 metres
  • Special extensibility
  • Storable
  • Fast curing
  • Smooth surface
  • Suitable for all profiles
  • Bridging of cross-section shape and size changes
  • Abrasion-resistant layer
  • Resin types depending on requirement (polyester resin / vinyl ester resin)

HF-Liner with IES: Additional advantage

  • Integrated installation protection (IES, available up to DN 600, no slip liner necessary)

Area of use (HF-Liner)

  • Gravity sewers
  • Circular profiles: DN 400 – DN 1,600
  • Ovoid profiles: 350/525 mm–1,200/1,800 mm

Area of use (HF-Liner with IES)

  • Gravity sewers
  • DN 400 – DN 600

High mechanical characteristics

The use of high-strength glass and the special arrangement of the glass sheets enables the liner to achieve high mechanical characteristics. These ensure a reduction in the structurally required wall thickness compared to the normal Berolina-Liner.

The Berolina and the HF-Liners are also available with integrated installation production (IES). A slip liner may no longer be necessary. The installation time is reduced by up to 60 minutes.
