The Berolina-Liner is composed of glass-fiber and/or polyester webs impregnated
Features
with polyester or vinylester resin. The layers are overlapped and staggered giving
the tube variable stretching capability. The liner is UV cured. The glass-fiber
layer provides sufficient axial strength for pulling the liner into place.
BKP produces the Berolina-Liner with a protective inner film and a UV resistant
outer film. The inner film is removed after installation. The outer film also
prevents resin from migrating into laterals. The liner is delivered pre wet-out and
ready for installation. The liner can be stored for up to 6 months without cooling.
Main Benefits
Claimed
• UV cured resulting in less CO2 emission and reliable curing results – neither
influenced by ground water, temperature and storage time.
• For same stiffness, thickness less than a polyester felt product.
• Inflation by compressed air (7.5 psig) allows CCTV inspection of liner prior
to UV cure.
• Suitable for circular and oval profiles.
• Designed with ring stiffness classes SN1250-10000 (MPa), which is similar
to GRP pipe for direct burial.
• Can bridge over profile or cross-section changes.
• Highest rating in IKT water impermeability tests.
Main Limitations • BKP production is located in Berlin, Germany.
Cited
• Not certified for use with potable water.
• No long-term pressure regression or tensile testing to substantiate a full
structural (Class IV) design.*
• No strain corrosion testing as per ASTM D5813 (6.4.2)*
• * Tests have been done and certified according to European and Japanese
standards. ASTM test will follow.

Service Connections Laterals are optically located (with CCTV) after curing and reinstated with
robotic cutters. No provisions for pressure connections.
Structural Rating No claim made in literature, but with stiffness class SN10000 through 20 inches
