Only high-grade materials areused in the Brandenburger GFRPpipe liner:• Polyester resin acc. DIN 18820
Group 3, Type 1140 and acc. DINEN 13121 Group 4 respectively
• Vinylester resin acc. DIN 18820Group 5, Type 1310 and acc. DINEN 13121 Group 7A
• Corrosion resistant glass fibre, socalled Advantex® E-CR glass fibres

Quick, safe and durable: The pipelining process
Construction:A cable winch pulls the Brandenburgerliner from shaft to shaft into thesewer to be rehabilitated. Once itis in place it is sealed at both ends.Due to a special longitudinal re-inforcement of glass fibres anoverexpansion or tearing of theGFRP pipe liner is impossible.
Curing:The new "pipe-in-a-pipe" is filledwith compressed air until itpresses form-fit to the old pipe.Under retention of the constantinner pressure the pipe liner iscured with support from a mobileUV light. The camera installed onthe light unit as well as thetemperature and pressure sensorsensure an exact process monitoringand documentation.
GFRP pipe liner - Renovation with high-performance materials
Stability, chemical resistance and endurance of the material used is decisive for successful
sewer rehabilitation. Therefore Brandenburger has been relying on glass-fibre reinforced
plastic (GFRP) for decades.
Clever composites defyextreme loads
GFRP composi te mater ia ls are ideal for
the trenchless sewer rehabi l i tat ion: The
Brandenburger GFRP pipe l iners can be
adjusted to the individual requirements in
all conventional sewer cross-sections. GFRP
pipe liners are capable of bearing extreme
loads at very low wall thickness.
The wrapping techno logy patented by
Brandenburger is unique. Compared to
conventional pipe liners a seamless design
is ensured and offers special advantages:
• Even wall construction and constant wall
thickness
• Constant stretch behaviour

Over 2 million metres of Brandenburger pipe liner DN 150 - 1000 have been installed in
sewer rehabilitation projects in 26 countries to this day - with the development of the
seamless, light-curing GFRP pipe liner Brandenburg has set an international standard for
the quality of trenchless sewer rehabilitation.
The basis for the Brandenburger expertise in pipe lining is the decade-long experience
with high technology materials: Besides the sewer rehabilitation, the developments of the
Brandenburg company are used in various other industries, for instance in the aerospace
industry.
Brandenburger Pipe Lining:
Advantages of the trenchlessrehabilitation
• Brandenburger pipe lining is cheaper and
considerably quicker than a reconstruction.
Noise, emissions and energy consumption
is reduced - local residents and road users
will be thankful.
• Brandenburger offers know-how from one
source: Liner material, UV light technology
a n d a p p l i c a t i o n t e c h n o l o g y m e s h
seamlessly into a c losed system that
results in high-grade quality curing on the
construction site.
• The glass-fibre reinforced plastic (GFRP)
used by Brandenburger offers first-class
properties for sewer rehabilitation: Better
mechanical characteristics and a lower
l iner wal l thickness than conventional
synthetic fibre liners ensure a sustainable
finished product.

Background Information on LightTechnology
The light curing procedure hasbeen used in industrial applicationssince the 1970s, such as for curingpaints in the automobile industry.
This technology was first used insewer rehabilitation work at theend of the 1980s.
In the light-curing procedure, theresin to be cured (UP or VE resin) isexposed to light of a specific wave-length (360 - 420 nm). Special lightinitiators in the resins ensure thatthe intended reaction occurs. Inthe resins being used, UV light canonly induce polymerisation whenfree radicals are present.
Exposure to UV light causes the"photoinitiator molecules" to de-compose into the radicals that arerequired for the polymerisationprocess. These induce polymerisa-tion by interlinking with the styrolscontained in the resin.

leak-proof...
The leak tightness of a liner is only guaranteed
with homogenous resin distribution. Therefore
the Brandenburger GFRP pipe liner is drenched
directly in the plant - in a standardised and
monitored process. There is no need to handle
chemicals at the construction site.
form-fit...
Brandenburger GFRP pipe liners are superbly
radial flexible due to the specially developed
glass-fibre composite. Thus the pipe liner
form-fits itself to the old pipe walls. Stretching
in the longitudinal direction is prevented by
the special alignment of the glass fibre.
storage stability...
Due to the UV l ight-curing process the
Brandenburger GFRP pipe liner can be stored
and transported without difficulty. Packed UV
proof into a transport box they are not sensitive
to high temperatures and can even be shipped
long distances.
and quick
Brandenburger GFRP pipe liners are distinguished
by quick curing times. The specially developed
resin plus the newest BLUETEC® curing tech-
nology makes the system the quickest one in
the market. The project construction time is
shortened and the sewer can be used again
sooner. The local residents and the traffic are
disturbed less and the costs are kept low.
GFRP pipe lining in practice
Current tests by independent inspection institutions on construction site samples confirm:
Brandenburger GFRP pipe liners have excellent results not only in the leakage tests, but
also for the achieved material characteristics (refer to: IKT-Liner Report 2003/2004 and
2004/2005, 2006 and 2007, www.ikt.de).
InnovativeUV light-curing technology
Uniform and fast curing
The quality of each pipe liner stands and falls with the applied curing technology. Since
1997 Brandenburger has been developing light-curing pipe rehabilitation technologies
and UV designs and produces these in a separate area.
Polymer
RadicalPhotoinitiator
UV lightMonomer
Brandenburger's UV light technology makes
an optimised and controlled curing possible:
The ent i re process can be contro l led
electronically and optically using TV cameras
from the outside.
In 2006, B randenburger l aunched a
completely new, advanced UV light-curing
technology under the BLUETEC® brand
name: With even more powerful UV halide
lamps, up to 300 m cable length, a new
control system and advanced UV l ight
sources the curing rate can be adjusted in
accordance with the diameter and the wall
thickness of the pipe liner as well as the
sewer profile (round, oval, special).
Light curing speeds of up to 180 metres
per hour (with DN 150) are possible with
BLUETEC® - therefore the l iner usage
becomes even more efficient.

Manufacturers and rehabilitation companies share obligation equally regarding quality
assurance in trenchless rehabilitation - the Brandenburger quality management system
includes the consistent quality inspection along the entire value creation chain:
• in the receiving department
• in the production process (in particular material traceability, resin viscosity, resin content
in the GFRP impregnation, electronic liner wall thickness and liner length documentation)
• in the execution of the rehabilitation, including the construction site approval
The Brandenburger pipe lining and the UV light-curing procedure developed for it both
have the necessary approvals and quality seals.
