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.
