​​Watertight welding of plastic membranes is one of many Leister competencies in underground engineering. In the late summer of 2021, VARIMAT and Co in Bern began the renovation of the Weyermannshaus open air swimming pool. Swimmers are set to return to their “Weyerli” from May 14, 2022.

The AZART Group of companies has its headquarters in St. Petersburg in Russia and has been manufacturing inflatable products made of PVC fabrics for state authorities and the entertainment industry for over ten years. In recent years, AZART has continuously expanded its product range and is now successfully represented on the market in various sectors.

​For the Winter Swimming World Championship in Russian Tura a pool basin was needed that could be implemented without heavy construction equipment. Klyaksa 72, an advertising company, is used to think out of the box and built the basin out of strong PVC mesh. Klyaksa could count on the great service of Olmax and Leister‘s UNIPLAN E hot air welder turned out to be indispensable for creating infrastructure. 

The 10th annual Winter Swimming World Championships was held March 8-12 in Tyumen, Russia. The competition drew 1,275 participants from 42 countries worldwide. Swimmers competed in events ranging from 25’s of all strokes to the 200 freestyle in pool filled with water from the river in Siberia. 

The swimmers had to compete in an open reservoir: a lake, a river, or a bay. One of the largest rivers in the Siberian Tyumen region, Tura was chosen as the venue of the 2016 Championship. It was necessary to build a pool basin, while resolving the following tasks: to ensure the safety of swimmers and compensate the current level of the river. Many options were discussed: from the manufacturing of an aluminum frame to drilling piles - these would be costly projects, the implementation of which would cost a few million rubles. 

The “D-Fitness” swimming pool (formerly the “Dynamo”) in Kazakhstan’s former capital and largest city, Almaty, was built in 1930. It was the only indoor swimming pool with 50-metre (164 ft) lanes, corresponding with Olympic standards, in the entire country until 1967. The need for refurbishment was so obvious by 2012 that a fundamental overhaul was initiated. The swimming pool was to be open to the public as well as to serve Kazakh athletes. The construction and building work for Olympic swimming pools is technically complicated. Compliance with strict specifications, which apply to such pools everywhere including Kazakhstan, was necessary for this, the largest pool in the country. 

​To meet the high quality standards, 1.6 mm PVC waterproofing membrane was used to seal the swimming basin – in a suitable, light blue color for swimming, of course. To ensure that the welding ​seams were completely hermetically sealed, Leister welders were used. The VARIMAT V2 hot air welder as well as numerous TRIAC S and TRIAC AT hot air tools from the Swiss manufacturer were employed. Historically, the VARIMAT V2 is primarily used for welding over-lapping plastic waterproofing membranes on roofs, but it is also suitable for connecting the sealing sheeting for swimming pools. With the VARIMAT’s understandable and easy to use «e-drive» control unit, relevant welding parameters for speed, temperature and air volume can be simply regulated and controlled. It is also very cost-effective with speeds of up to 12 m/min (39 ft/min). Leister’s well-known reliability also applies to the manual welders in the TRIAC series. Here, the welders were used for detail work on closures and details such as stairs and drains. The TRIAC AT has a display that allows both the temperature and the air volume to be digitally-monitored. 

Albania is one of the fastest growing countries in terms of economy in southeastern Europe. Between 2004 and 2008, the average economic growth was 6%. On November 28, 2012 Albania celebrated its 100th year of independence from the Ottoman Empire, an important event for a proud nation. The center of the capitol, Tirana, was festooned especially sumptuously for the occasion. A gigantic Albanian flag covered the facade of the International Hotel, the highest building in the heart of the city of Tirana.

A landmark for two months.
The flag was manufactured by the Sakuli Sign & Printing and was 1,254 square meters in size. It was the largest Albanian flag ever made in Albania. It was printed on PVC mesh material in multiple strips which were then connected using Leister welders. According to Sakuli, they only considered Leister technology because they wanted to ensure the quality and durability of the welded seams. The overlapping seams were welded with a UNIPLAN E, while TRIAC S hot air hand tools were used for handling the details. Up to 14 employees worked on the printing, welding and assembly work. The installation work on the facade of the hotel itself was completed in just one night. The flag hung for two months over the hotel facade and could be much admired and photographed by passersby as a landmark of the capitol.

Perfection is mandatory in professional sports: Mistakes are costly, timing is critical and excellence requires precise form. The same holds true when you weld banners for some of the biggest names in athletics.

American signage firm AMI Graphics has a customer list that includes the National Hockey League (NHL), the National Basketball Association (NBA/Boston Celtics) and other professional sports leagues nationwide.

AMI designs, welds and delivers the solid and mesh vinyl banners these leagues use to advertise at some of the country's biggest arenas. AMI's customers often need these banners on tight deadlines, since championship contenders are frequently decided shortly before the finals actually occur. That means AMI must complete large signage projects while on the clock. And like any match that comes down to the wire, the pressure is intense.

Basle is "the" Art City in Switzerland. The numerous museums of classical and contemporary art attract hundreds of thousands of visitors. It is also where the "Art" is staged every year, the biggest art fair in the world. Culture in general and the fine arts in particular have a long tradition at the Rhine bend. It is supported here equally by the public and by politics. So it's no wonder that a project was possible in Basle which would have had no chance anywhere else: The City Sky. The Christophe-Merian Trust, the Basle City Canton and a lottery fund support this art and culture project of the initiator and organizer Klaus Littmann. 

The Boston Museum of Science wanted to find a unique marketing idea to promote its upcoming exhibit on the sci-fi phenomenon Star Wars. It was decided that the building’s 60m m circumference, 14 m tall dome was to be transformed into the head the movie’s robotic character, R2D2.

Visitors to Beijing often report to be deeply impressed by the rapid growth and the prosperity of Beijing. More and more companies have become aware of the enormous potential of this economic hotspot. Due to their efforts to maximize advertising impact for their businesses or one of their brands, billboard advertising has become one of the most important marketing instruments in China. The advantage of billboards is that they, at relatively little expense, attract the attention of a large target audience. Whether it be on large city squares, alongside business avenues or the highway to suburbia, or wrapped around new buildings: Wherever you turn the eye, you will see billboards, telling the passersby: “Yes – we are here!” RIKON, a big name in Beijing’s billboard industry these days, has become aware of the increasing demand on the billboard market a few years ago. Over the last few years, this company has become market leader.
