Brandenburger Liner GmbH & Co. KG

Brandenburger Liner GmbH & Co. KG, based in Landau in der Pfalz, Germany, is a medium-sized, family-managed manufacturer within the Brandenburger Group, which has operated for over 90 years. The company focuses exclusively on UV light-curing glass fiber reinforced plastic (GRP) pipe liners for trenchless sewer rehabilitation, having produced more than 10 million meters of liner since the mid-1990s using its patented seamless winding manufacturing process. The flagship BB2.5 liner series covers circular pipe profiles from DN 150 to 1,600 and egg-shaped profiles from DN 200/300 through 1,200/1,800, available with UP (unsaturated polyester) resin rated to 50°C and VE (vinyl ester) resin rated to 70°C. The BB2.5 FLEX variant permits up to 35% elongation during installation to accommodate diameter transitions, curved pipe sections, and special geometries without requiring pre-specification of pull-in direction. The BB2.5 VERTICAL is the industry's first manhole rehabilitation liner compatible with both UV and LED curing, available for DN 800 and DN 1,000 round shafts and bearing the RAL-GZ 961 quality mark. BB Protect provides semi-finished composite casings that wrap pipes for mechanical damage protection during trenchless installation methods like horizontal drilling and auger boring, cured by UV light on-site. All products hold DIBt Approval Z-42.3-490 (valid through 2027) and WRc Approved certification, with a projected service life exceeding 50 years and abrasion resistance of 0.07mm after 100,000 DIN EN 295-3 cycles. The company also operates a Rental Park providing UV curing systems, light chains, conveyor belts, packer sets, winch equipment, and curing vehicles for liner installation projects.
