The Brandenburger Liner BB2.5, which is available in all nominal widths, features glass mats with a unique design. This results in a high strength material that meets even the highest static loading requirements and at the same time making it possible to select the thinnest piping hose liner. Brandenburger provides additional external protection, which with its two-layer, fibre-reinforced design protects the liner against any damage before, during and after installation.
In accordance with the modified DIBt certification Z-42.3-490, liners with a DN > 875 have a short-term circumferential elasticity modulus of 16.875 N/mm².
This has been made possible by the redesign of the winding technology on our fourth production line. The new ultramodern plant still uses the winding process by Brandenburger in 1996, for which we still hold a patent, however this process has been refined yet further. This technical progress is also reflected in every further production step; for example, when transporting the film as well as packing away the liners into the transport crates that have been especially designed in-house.

Each of our produced pipe liners is packed into an own wooden crate at no extra cost. This is adapted to the ordered pipe liner and manufactured individually for each customer in our own carpenter's shop. The wood used is adapted to the specific needs of the construction site.
The subsequent shipping of the materials to the construction site is planned by our order processing department. We cooperate with a transport specialist to make a hassle-free construction site workflow possible.
