In the year 2007, the power company “Vilniaus Energija” from Vilnius, Lithuania restored the outside of the chimney of its coal power plant. The restoration works were carried out by UAB "Multikontraktas", the Lithuanian partner of KÖSTER BAUCHEMIE AG.
The chimney H250 had an outer hull made of reinforced concrete. The concrete had suffered some damages over time. Due to bad concrete quality, insufficient concrete cover and poor workmanship during the construction of the chimney, the steel reinforcement close to the surface had corroded in many places. Due to the expansion in volume of the corroding steel, the concrete over the corroded steel reinforcements was damaged and the corroded steel reinforcements were exposed. Due to poor workmanship, the concrete surface was full of pinholes and especially in the areas of the construction joints, the surface was very uneven.
During the restoration of the chimney, the protruding steel reinforcements and concrete protrusions as well as loose particles were removed. Afterwards high pressure water cleaning of the entire outside of the chimney was carried out. The concrete was then repaired using KÖSTER Betomor Multi A in the damaged areas. It was subsequently protected using KÖSTER Repair Mortar and KÖSTER Betomor C-Coat on the entire outside of the chimney. After the restoration work the chimney was painted to achieve the red and white warning markings. >> Reference
During the Olympic Games in summer 2008 the attention of many people will be concentrated on the Olympic Sport Arena in Beijing. For this reason we are proud that our affiliate Beijing KÖSTER International Chemistry Co., Ltd. waterproofed the cistern, air ducts, wastewater channels and tanks of this building. An area of 15.578 square metres was waterproofed with KÖSTER products.
By finishing this prestigious and important job successfully, we have gained an excellent reference for future projects.

The new waterproofing product KÖSTER NB 1 "Fast" combines the technical advantages of the proven KD System with the positive application properties of KÖSTER NB 1 Grey. Fast waterproofing from the inside against non-pressurised water is now possible.
KÖSTER NB 1 "Fast" thereby closes the gap between fast waterproofing against pressurised water (negative side waterproofing against leakages with the KD System) and plain plastering of moist walls with a combination of KÖSTER Polysil® TG 500 and KÖSTER Restoration Plaster 2 "Fast". >>more...

Concrete repair is one of the focal points of this issue. Concrete and steel reinforcement frequently suffer damage. The causes can be manifold. However, whether the damage arises from natural aging, from environmental influences, from overloading of the statics, incorrect planning and application procedures or faulty design, in order to retain the value of a building, damaged and corroded parts of the structure must be professionally repaired as soon as possible.
This requires the appropriate products. For decades, the innovative development of new systems has been our strength in the construction chemicals market. Via close association with users and planners, we work from the perspective of "What comes out of the market, goes into the market".
A development from this parnership-like collaboration is described in this Waterproofing Report: KÖSTER Betomor® Multi A – a product that stands out because of its excellent technical features. It is another step towards long lasting restoration of structural members. >> more...

Sealing against radon
The sealing against radon naturally requires extreme
care during sealing work and a waterproofing material
with appropriate radon-tightness. We would like to
emphasize at this point, that the following described
waterproofing materials and systems are not measures
for shielding against radioactive radiation, but suitable
for sealing against radioactive gas.

Below ground cable and pipe penetrations into buildings have always been considered the weak and complicated details for the waterproofer. Especially in these areas, the waterproofing materials are subjected to groundwater, rain water and resultant pressurised water – with the common consequences of leakages, efflorences, mould patches and high humidity. With the KÖSTER KB-Flex 200, the KÖSTER BAUCHEMIE AG has launched a reliable product targeted for especially these kind of problems. The material is simply used directly from the cartridge and works instantly without waiting for cure! >>more...
