BBconeflex promo-tour in Denmark - already more than 300 manholes rehabilitated

In September, our customer Villy Poulsen, along with our jobsite technicians, were on a promotion tour in Denmark for our manhole liner BBconeflex.
Over the course of 7 working days, a total of 14 manholes DN 1000 in various cities and municipalities from Jylland to Sjælland have been successfully rehabilitated and the results are impressive!
We are looking forward to the second BBconeflex tour with Villy Poulsen in November 2019.

If you are interested in the BBconeflex, please contact our sales colleagues.
 

 

"Working where others go on vacation" - this is the motto at which Brandenburger Liners are installed at Brussels Airport.

As part of the ongoing renovation work around Brussels Airport, our Belgian customer Viabuild! installed another Brandenburger Liner BB2.5 at the end of August 2019.

With an egg profile DN 1200/1800, wall thickness 12.6 mm, a length of 150 m and a total weight of more than 15 tons, the advantages in handling of a Brandenburger Liner are particularly evident. The pre-impregnation of the glass fibers enables a higher viscosity of the resin in the prefabricated liner, which considerably facilitates the handling of such a long and heavy liner on the jobsite. Despite the long duration of installation and curing time, the resin remains in place and ensures, in addition to clean equipment, especially a homogeneous wall thickness and a uniform ratio of glass and resin.

DN 1600 at Lisbon Airport - one of the largest UV liner on the Iberian Peninsula

One of the largest UV liners on the Iberian Peninsula was installed at the End of August 2019 at the Aeroporto de Lisboa. A Brandenburger Liner BB2.5 DN 1600 with a wall thickness of 9.8 mm is already a challenge for experienced UV crews and requires careful planning.
If the installation company has been in possession of a UV system for just a few weeks at the time of installation and has only installed a few, smaller UV liners before then, then the task is even more challenging. But with careful planning, constant communication of all involved and professional guidance, such an installation can be crowned with success.
 

Liner installations in the project "Lund - Arlöv, four tracks" in southern Sweden.

In close proximity to the Öresund Bridge, our Danish customer Villy Poulsen installed just under 500 m of Brandenburger Liner BB2.5 DN 600 / 5.6 mm along the railway line between Lund and Arlöv in southern Sweden in August 2019.
Despite several inaccessible intermediate shafts, the liners could be installed successfully and without overstretching without previously installed full-preliners or safety caps.
 

Liner installation between creek and vegetable patch

In Waldaschaff, our customer Geiger Kanaltechnik, section Mainaschaff successfully installed a total of around 500 m. Brandenburger Liner BB2.5 egg profile DN 700/1050 and DN 800/1200.
With complex water management and hard to reach manholes the jobsite was a real challenge. For example, equipment such as our rental winch had to be placed by crane over the creek of the Aschaff, past greenhouses, between the children's swing and the trampoline in the gardens of the residents.
However, in cooperation with our jobsite technician, the UV3 crew of Geiger Kanaltechnik mastered all challenges with flying colors and impressed the present representatives of the client.

Liner installations as part of the “Northern Corridor Improvements” project in Auckland, New Zealand.

As part of the construction of a direct motorway connection between Auckland Airport, West Auckland, Manukau and Hamilton several Brandenburger Liners will be installed. In June 2019, the first and at the same time heaviest UV liner (over 15.5 tons total weight, length 162 m.) was successfully installed by our customer Pipeworks.

Due to the high resin transparency and reactivity, the Brandenburger Liner BB2.5 DN 1150 could be produced and cured without addition of peroxides despite a wall thickness of 16.1 mm.

So why not use our know-how to rehabilitate manholes?

We, the pioneers and one of the world's leading manufacturers of UV-curing GRP liners, set ourselves the task.

As a result, we are pleased to present the new BBconeflex today.

Together with the company Max Bögl it was possible to successfully rehabilitate 6 manholes in the city of Kiel at the end of June.

The company Rainer Kiel had a joint project with us at the end of May in the Swabian town of Ludwigsburg.

Various nominal diameters were installed, including a DN 1400 / 11.2 mm with a net weight of seven tons, which was pulled directly from the truck via a conveyor belt into the canal.
The liner was cured at a wall thickness of 11.2 mm at 60 cm / min with a system output of 12 x 1000 watts.

 

PS2000 from Madrid installed 500 m of liner in May.

The special features of this project were not the nominal widths, and the construction site was also nothing out of the ordinary, yet we would still like to briefly illustrate our bond with the company:

 in 2012 a young man from Spain asked whether he could work in production at our company to learn German.

Six months later he asked whether we could not also get him a job in the UV line. He wanted to improve his understanding of liner installation to apply and teach acquired skills in Spain.

 Five years later, Yary Mesa and his company PS2000 have started to turn their backs on having to manually clean sewage and are slowly moving towards keyhole sewage refurbishment using UV liners.

In this context, he is fighting for more projects every day to be able to further enhance his machinery and offer his professional services throughout the country.

 

We are proud of Yary Mesa's success and are delighted that we were able to support his development at such an early stage! All the best from Landau to Madrid! We hope you continue to be successful in the future!

 

The Storebælt Bridge in Denmark with a total length of 18 km is one of the longest suspension bridges of the world and links together the eastern and western parts of Denmark. Finished in the year of 1998 the bridge replaced the existing ferry service between the danish islands Fyn and Sjælland and represents now a fixed link. The advantages of the trenchless sewer rehabilitation at this construction site were significant. The intense traffic was almost not affected because of the minimum space requirement of the site equipment and sewer immediately usable on completion of refurbishment work. In a narrow time window 5 liners with a total length of 200 meters could be installed in the area of the toll station. We congratulate our customer Villy Poulsen on this excellent result!

The sewer rehabilitation sector in Lithuania is growing steadily. Despite the cold weather and snow, the Poli installation team installed a 550 metre long Liner DN1000 in the Lithuanian capital. We are pleased to have been able to contribute to this growth with this project and congratulate Poli on this excellent result.

 

Premiere for Brandenburger: At the beginning of November, the first Brandenburger liner was installed in the Ukraine. In Zaporizhia, which is the sixth largest city in Ukraine with a population of around 760,000, the 105-metre-long liner DN 500/4,9 mm was installed in a steel pipe.

Liner Installation in front of a special backdrop– In the middle of one of Europe's most popular golf and real estate resorts.

Because of the difficult set-up at the construction site and the lack of space, care was needed, especially when dealing with the sophisticated residents and plant operators. In the end, the liner with a total lenght of 700 m, a diameter of DN 200 and a wall thickness of 4.2 mm was installed with an amazing result.

In Tampere last October the thickest liner ever produced was installed in cooperation with Eerola. With a wall thickness of 22.4 mm, a conduit of 80 m was to be renovated with a change of dimension of DN 1500 to 1700. Despite the challenging traffic conditions, the installation was trouble-free, with the end result speaking for itself.

In the North Island of New Zealand, more specifically the Bay of Plenty, a liner with a nominal diameter of DN 1000 and length of 60 meters was installed in a paper mill. From our location in landau to the target construction site, the liner has covered a total distance of 18.477 km, making it the most travelled Brandenburger liner so far. Our application engineer has also taken the long distance to support the installation team on site, so the liner could be installed with a successful result.

New conditions, New Challenge: This was our Motto for the order to produce the Brandenburger Liner BB2.5. No Standard liner, no standard Transport, and no conventional production. During the preparation of this gigantic Project, each and every process step had to be checked and implemented for the new record weight.

Saint-Paul is a municipality in the French overseas département and region of La Réunion, the second largest on the island in terms of population. It is at the centre of a conurbation of more than 170,000 persons, which also includes the municipalities of Le Port and La Possession. For the refurbishment of its sewage network, St Paul municipality decided to opt for Brandenburger Liner BB2.5.

The PRV Brandenburger BB2.5 pipe liner system offers significant advantages, not least of which is the increased transparency of the liner, especially for small or large diameter pipes. This makes it possible to polymerise wall thicknesses of 15 mm by UV radiation. The long-term modulus of elasticity of 6 210 N / mm² of the BB2.5 liner in a wet acidic environment also creates a significant margin of stability, even for relatively small wall thicknesses, which also enables minimalisation of the cross-sectional area. A fabric-reinforced outer film facilitates smooth installation over the entire range of dimensions; this optimally prevents infiltration from the water table and excludes the risk of saponification.

In Vlissingen in the Netherlands, the company Kumpen recently refurbished a 60-year-old wastewater collection drain. Decisive factors in winning the contract were the short construction times and the integrated refurbishment concept.

The growth rate of liner installation using UV technology has also grown strongly outside of Europe over the past years.

Nevertheless, it still takes a lot of effort at persuasion and an intensive communication with the clients to establish UV technology next to conventional methods. We were able to accomplish this together with our customer SG Ingeneria in Columbia.

Currently Brandenburger Liners are being installed in Bogotá, a metropolis with 8 million inhabitants. The project encompasses several kilometres in the centre of the city. That is why the installations are usually carried out at night so that the totally overloaded traffic network is not aggravated more than necessary.

We are looking forward more kilometres in 2018!

During the school holidays, a sewer line needed to be renovated under the classrooms of the Wilhelm Leuschner primary school in Egelsbach.
The local conditions were anything but “daily bread”. Thus a line reach of 104 meters as well as a dimension change from DN 800 to DN 900 needed to be renovated in a closed intermediate shaft. The Brandenburger Liner BB2.5, with its patented winding technique, is the perfect solution to satisfy all requirements of such a project.
The renovation of line reaches and sewers with a change of dimensions always poses a special challenge for man and material. Only good project preparation, high-quality hose liners and a professional installation can reduce risks such as overstretching or wrinkling and ensure a good result.
We wish all pupils and teachers of the Wilhelm Leuschner primary school a good start into the new school year!

A so-called hood profile with a dry water gutter was successfully rehabilitated in the heart of Barcelona in August 2017 by the Madrid-based company PS 2000 in cooperation with the Brandenburger company.

It was not only the narrow streets that made the application engineers of the two companies sweat, but temperatures of around 40 °C also posed a special challenge for the liner installation.

Nevertheless, the 8-tonne liner with a length of over 93 metres was successfully installed, taking into account the four intermediate shafts and a 30° bend.

As part of the rehabilitation of the entire airfield at Vilnius International Airport, a DN 1500 collection drain was rehabilitated.

In the summer of this year, flight traffic was suspended at the airport. In a tight time frame of just four weeks, in addition to the tarmac works, new shafts had to be set and a 300 m collection drain with a diameter of DN 1500 rehabilitated.

Thanks to good planning, three insertions were implemented by our customer Pozemines linijos in the first week alone, despite the works being repeatedly hampered by rain.

All in all, the operational plan was adhered to and the collection drain was successfully placed back into operation before the airfield rehabilitation was completed.

 

Cold, colder, Oulu: At -15 degrees Celsius in November the team from Brandenburger Liner GmbH & Co. KG in Landau and Putkistosaneeraus Eerola Oy in Finland installed two 16 tonne liners in a sewer beneath the Finnish city. This was quite a feat under these chilly conditions not only for the workers, but the technology too defied the cold.

Installing a 280-metre-long GFRP pipe liner with a 1500 diameter and only ten millimetre thickness is quite a feat. And to pull it all off under a river with the sewer separated from the river's water by only one metre of earth – that is something else entirely. That is what Brandenburger Liner from Landau accomplished in Krakow, Poland, in August under somewhat difficult circumstances.

No entries found.

Installing 96 tonnes of liner in ten days in 620 meters of sewer – right next to one of Helsinki's main traffic arteries. The construction site in the Finnish capital in May 2016 was not only a great challenge for the team of the Putkistosaneeraus Eerola Oy company and of Brandenburger Liner GmbH & Co. KG. It was also the largest single project for sewer rehabilitation in Finland.

A construction site against a historical backdrop was the challenge for the team from Kumpen NV and Brandenburger Liner GmbH & Co. KG in the Belgian city of Ghent. At the “Korenmarkt”, the historical centre of Belgium's third-largest city, two liners needed to be installed. The challenge: the not very “classical” form of the sewer which required a special solution. And then there was the location: The pipes to be rehabilitated underpass the tram line next to a church.

In 2015, the PRFV LINERS Company has, in cooperation with Brandenburger, renovated sewers in the heart of Buenos Aires with more than 4,000 metres of pipe liner.

Not only were the logistics and the actual transport overseas a great challenge, but also the actual installation of a 24-tonne heavy and 330-metre long oval profile with a diameter of 900/1180.

One of our application engineers was on site to provide professional support and to coordinate on the construction site. Simply the 24-hour curing of the 165-metre long section made this necessary.

Due to special circumstances, the water drainage could be put into operation for only a short period. The time window from the measurement of the UV pipe liner till the conclusion of the rehabilitation project was only four workdays.

Friday: The water drainage was put into operation briefly to ensure the measurement of the liner - production of the liner on the weekend and delivery on Monday.

Monday: The water drainage was put into regular operation (with two persons, 24 hours as pump monitors) and cleaning the conduit and the shafts carried out (8 hours all together).

Tuesday: Installation of the UV pipe liner with preceding cleaning and TV inspection.

Wednesday: Completion of the remaining work and putting back into operation.

The rehabilitation of brook is generally not considered an especially unusual construction project. In Hornsburg this was something different however.

The many changes of direction, bends up to 30° and the constrained circumstances needed to be taken into special account for planning the construction site. Thus all installation steps commenced from the high point.

In practical terms this meant that first the winder was at the shaft, then the winch was raised by a crane at the shaft and secured by a lorry so that finally the UV system could be positioned at the shaft.

The results spoke for themselves.

A night-time construction site under difficult conditions.

Due to the heat during the day, the enormous amount of traffic and the water flow of the sewer, the installations were carried out at night.

The water drainage was built up for a length of 1 km with three pumps and two additional suction vehicles in non-stop operation to pump out the installation shafts.

Many interested persons of the local municipalities, participating companies and the water works came to this pilot project.

Due to the success of the project, trenchless UV pipe liner sewer rehabilitation has become known beyond the country's borders.

No bend too sharp: Swietelsky-Faber installs Brandenburger pipe liners with bends of up to 90° in Augsburg

Augsburg is one of Germany's oldest cities and with approximately 280,000 inhabitants it is the third largest city and economic powerhouse in Bavaria. Three rivers run through Augsburg: the Lech, the Wertach and the Singold. The Singold, which has its source in Ostallgäu, leads into an intricate network of artificial streams and canals in a district of Augsburg. The large number of canals in Augsburg – most of which flow through theLech Quarter in the Old Town – means the city is full of bridges; Augsburg's 500 bridges even outnumber the bridges in Venice. As the oldest city in Bavaria and the second oldest in Germany, Augsburg is able to look back on a long tradition. Despite this or precisely because of it, it is necessary to think outside the box when it comes to the rehabilitation of drainage systems. The construction project in Augsburg was focused on hand-masoned sewers built in the 20th Century. After 102 years, it was necessary to rehabilitate these DN 700/1200 and DN 800/1200 oval profile sewers.

272 metres of large profile in 48 hours High-speed rehabilitation of walkable oval profile sewers using GFRP pipe liners

It is common knowledge that trenchless sewer rehabilitation offers significant advantages in speed over open-pit methods. However, the rehabilitation of 272 metres of a walkable oval profile sewer within 48 hours remains an astonishing feat. Yet this is what happened in Kaiserslautern, Germany, where experts from Leipzig-based tubus GmbH used a BB2.5 light-curing GFRP pipe liner by Brandenburger to rehabilitate a 125-year-old collection drain in late summer, 2014.
