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.
