Fast, effective and trenchless

The Berolina-Liner System is a cost-effective and efficient method for sewer pipe rehabilitation. Time-consuming excavation work can be avoided – the disruption to infrastructure is minor and short-term. Compared with other methods energy consumption is reduced significantly thanks to optimised production, transportation and installation conditions. Since 1997, BKP has successfully produced UV light-curing and glass fibre reinforced tube liners.

Different liner types are available to meet most requirements for sewers in need of rehabilitation:

Berolina-Liner Einsatzbereich

High mechanical characteristics enables low cross-section loss

The Berolina-Liner provides optimum benefits for trenchless rehabilitation of wastewater sewers, for every user. The factory resin-impregnated liner is pulled into the existing pipe to be rehabilitated, pressed against the old pipe by with compressed air and cured using UV light. The sewer pipe is thus sealed from the inside and its structural load-bearing capacity is restored. Depending on the requirements, the glass fibre layers of the liner are impregnated with high-quality unsaturated polyester or vinyl ester resins. They are arranged in such a way so as to overlap and offset with each other between two water and polystyrene-tight film tubes. The glass fibre orientation is also matched to the existing pull-in forces of the liner. Thanks to the glass fibre reinforcement, small wall-thicknesses are sufficient to strengthen the old pipe permanently. The loss in cross-section of a rehabilitated pipe is thus reduced to a minimum and the load-bearing capacity of the pipe system is simultaneously improved. Curing speeds vary depending on the diameter and wall thickness of the Berolina-Liner.

Highly adaptable due to particular flexibility

The seamless and undersized initial construction provides the Berolina-Liner with a high degree of variability and in particular extensibility or elasticity, which enables the liner to lie flush with an old pipe made of any material. If planned and preassembled appropriately, it adapts itself to any profile; small cross-sections or profile changeovers up to a maximum of eight percent of the nominal diameter are generally not a problem. The structural glass orientation in the circumferential direction optimises the flow of force without limiting the extension. All BKP Berolina liners are produced with a protective inner film included, which is particularly resistant and is easy to remove after installation. The UV-tight outer film bonded onto the liner is also standardised. At the request of the customer, the tube liners can also be offered with optional Integrated Enhanced Security (IES), as a substitute for the conventional smooth slip film, for less damaged sewers. In addition, Berolina-Liners have an abrasion protection layer on the inside.
