Brandenburger Liner BB 2.5

The BB 2.5 liner is used for the rehabilitation of municipal sewer systems and is manufactured to the required length. It is made from glass fibre reinforced plastic (GFRP) with an unsaturated polyester (UP) resin matrix. The liner is pulled into the existing pipe, expanded, and cured using UV light to achieve a close fit with the inner wall. It then works in conjunction with the host pipe to carry structural loads. The liner has a technical service lifespan of 50 years.
