Brandenburger Liner

innovation in technology and application

Brandenburger develops and manufactures pipe liners in-house for trenchless sewer rehabilitation (link to "Applications" – "Trenchless sewer rehabilitation"). What makes it so special is the patented wrapping technology, with which we have produced a total of more than 7,000,000 metres of pipe liner over the last 20 years. Our pipe liners are hardened with UV light, forming a new pipe within the old one.

The pipe liners are wrapped to form a tube with pre-impregnated laminate rolls. This creates a uniform wall thickness and with pre-impregnation complete penetration of the resin into the glass fibre matrix can be guaranteed. This ensures that there are no flaws in the material and a full-surface pure resin layer forms on the surface of the pipe liner.

As the dimensions, cross-sections and mechanical loads differ depending on the channel to be rehabilitated, we offer a suitable product for every situation combined with technical advice.

There are two product types, each of which has advantages in its respective field of application:

Product name Brandenburger Liner BB1.0 Brandenburger Liner BB2.5
Range of applications Small nominal widths, ARZ II to cope with higher static loading
Nominal widths DN 200 - 300 DN 150 - 1600
Wall thicknesses Total wall thickness = 4.3 mm From 3.0 mm to 17.5 mm without peroxide Combination hardening from 17.5 mm
Advantages of economical, environment-friendly sewer rehabilitation with UV pipe liners:

-          Short duration of the rehabilitation work – no need to dig trench

-          Minimum disturbance of local residents

-          Hardly any disruption to traffic due to minimum place requirement of site equipment

-          Sewer immediately usable on completion of refurbishment work

-          TV inspection of the product before final hardening

-          Minimal impact on the internal diameter of the sewer
