The solution for manhole rehabilitation. Flexible and easy to handle with enormous stretchability and precise adaption to the respective manhole geometry.

The Liner for special geometrie and profiles, rehabilitation of bends and changes in dimensions. All geometries availabe. Flexible in installation as the installation direction and position of dimension change do not need to be known.

The CIPP for all diameters with high mechanical strength and glass fleece-bonded wearing layer. Even with the highest static requirements and the thinnest possible liner a suitable variant can be selected.

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.

Our Brandenburger manhole liner reduces logistical effort for our customers at the jobsite and allows an efficient as well as a holistic rehabilitation of the sewer network including manholes and sewers.

The result is our latest development: the Brandenburger BB^2.5 VERTICAL. It’s the world’s first UV manhole liner that will adapt to the shape of the manhole just by air pressure. This prevents any time-consuming measurements of the manhole in the run to the rehabilitation.

Our special designed stretchable GFR laminate generates three important advantages: 

• Beforehand, no measurements of the old manhole are necessary: only the size of the manhole opening and the size of the manhole it self are needed.

• Endless production: with our special production technology, we are able to produce all manhole liners at a stretch for diameters between 800 – 1000.

• Rehabilitation from the manhole bottom up to the sewer pipe: with a special installation procedure, it is also possible to rehabilitate the bottom of the manhole with our material.

BB^2.5 FLEX – THE liner for special geometries, special profiles, rehabilitation of bends and changes in dimensions.

That makes BB^2.5 FLEX special:
+ Safe installation due to the use of a folded inner foil.

+  All geometries available.

+  Possible dimensions from DN 250 to DN 1600 (BB^2.5 FLEX) and DN 1600 to DN 2200 (BB^2.5FLEX XL)
+ Im Rahmen des BB2.5 DiBt-zugelassen.
+ BB^2.5 FLEX and BB^2.5 FLEX XL are flexible in installation, as both the installation direction and the position of the dimension change do not need to be known.
+ Transport advantage of the BB^2.5 FLEX XL due to production on base of DN 1600. This makes the Liner fit on a standard truck or in a standard sea freight container.
