Our partner in Germany and the former east, Schmid Wopfing developed Baumit into a global player; the Wietersdorfer worked the markets of the former Yugoslavia, Baltic countries, Russia, as well as Greece and Italy. The product portfolio has been continuously developed in such a way that Baumit is on par with large global players. In 2016\/17, Wietersdorfer changed its strategy to focus on the core competencies of cement and pipes. We have been operating in these fields of business since 1893 and 1931 respectively. For future opportunities and to take better advantage of these business segments, it was decided to hand Baumit over to experienced hands, so that core competencies can be further expanded. The brand Kema was also signed over to Schmid Holding along with Baumit.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-clearfix\"><\/div><\/div>\n<\/article>\n<\/div><h4 class=\"fusion-timeline-date\" style=\"background-color:var(--awb-color7);\">2013<\/h4><div class=\"fusion-collapse-month\"><article id=\"blog-1-post-13475\" style=\"border-color:var(--awb-color7);\" class=\"fusion-post-timeline fusion-clearfix fusion-left-column post-13475 post type-post status-publish format-standard has-post-thumbnail hentry category-history\">\n<div class=\"fusion-post-wrapper\" style=\"background-color:rgba(255,255,255,1);\">\n\n\t\t\t<div class=\"fusion-flexslider flexslider fusion-flexslider-loading fusion-post-slideshow\" style=\"border-color:var(--awb-color7);\">\n\t\t<ul class=\"slides\">\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li><div  class=\"fusion-image-wrapper\" aria-haspopup=\"true\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.wietersdorfer.com\/en\/polo-kal-xs-a-revolution-in-building-drainage-systems\/\" aria-label=\"POLO-KAL XS: a revolution in building drainage systems\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"800\" height=\"534\" src=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/2013\/01\/polo-kal-xs.jpg\" class=\"attachment-full size-full wp-post-image\" alt=\"\" srcset=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/2013\/01\/polo-kal-xs-200x134.jpg 200w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/2013\/01\/polo-kal-xs-400x267.jpg 400w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/2013\/01\/polo-kal-xs-600x401.jpg 600w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/2013\/01\/polo-kal-xs.jpg 800w\" sizes=\"(max-width: 1024px) 100vw, (max-width: 640px) 100vw, 40vw\" \/>\t\t\t<\/a>\n\t\t\t\t\t\t\t<\/div>\n<\/li>\n\t\t\t\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/ul>\n\t<\/div>\n\t<div class=\"fusion-post-content-wrapper\" style=\"padding:30px 25px 20px 25px;\"><div class=\"fusion-post-content post-content\"><div class=\"fusion-timeline-circle\" style=\"background-color:var(--awb-color7);\"><\/div><div class=\"fusion-timeline-arrow\" style=\"color:var(--awb-color7);\"><\/div><h2 class=\"blog-shortcode-post-title entry-title\">POLO-KAL XS: a revolution in building drainage systems<\/h2><div class=\"fusion-post-content-container\"><p>October 2014 saw the introduction of a minor revolution in the pipe industry \u2013 the birth of the POLO-KAL XS caused repercussions that would be felt beyond the sector.

The new kiln producing highly reactive quicklime has an authorized capacity of 300 tons per day. Apart from natural gas it can be operated with pulverized solid fuels like brown coal dust. The energy efficiency of the PFR kiln is very high so that it saves 18m\u00b3 of gas per ton lime versus the previous kiln. Of course this influences the CO2 balance positively. The PFR Kiln in Peggau is the first lime kiln in Austria with a permanent monitoring of emissions like dust, SO2 or NOx.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-clearfix\"><\/div><\/div>\n<\/article>\n<\/div><h4 class=\"fusion-timeline-date\" style=\"background-color:var(--awb-color7);\">2008<\/h4><div class=\"fusion-collapse-month\"><article id=\"blog-1-post-13485\" style=\"border-color:var(--awb-color7);\" class=\"fusion-post-timeline fusion-clearfix fusion-right-column post-13485 post type-post status-publish format-standard has-post-thumbnail hentry category-history\">\n<div class=\"fusion-post-wrapper\" style=\"background-color:rgba(255,255,255,1);\">\n\n\t\t\t<div class=\"fusion-flexslider flexslider fusion-flexslider-loading fusion-post-slideshow\" style=\"border-color:var(--awb-color7);\">\n\t\t<ul class=\"slides\">\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li><div  class=\"fusion-image-wrapper\" aria-haspopup=\"true\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.wietersdorfer.com\/en\/eroeffnung-des-logistikzentrums-leonding\/\" aria-label=\"Er\u00f6ffnung des Logistikzentrums Leonding\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"490\" height=\"368\" src=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/2008\/06\/2008.jpg\" class=\"attachment-full size-full wp-post-image\" alt=\"\" srcset=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/2008\/06\/2008-200x150.jpg 200w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/2008\/06\/2008-400x300.jpg 400w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/2008\/06\/2008.jpg 490w\" sizes=\"(max-width: 1024px) 100vw, (max-width: 640px) 100vw, 40vw\" \/>\t\t\t<\/a>\n\t\t\t\t\t\t\t<\/div>\n<\/li>\n\t\t\t\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/ul>\n\t<\/div>\n\t<div class=\"fusion-post-content-wrapper\" style=\"padding:30px 25px 20px 25px;\"><div class=\"fusion-post-content post-content\"><div class=\"fusion-timeline-circle\" style=\"background-color:var(--awb-color7);\"><\/div><div class=\"fusion-timeline-arrow\" style=\"color:var(--awb-color7);\"><\/div><h2 class=\"blog-shortcode-post-title entry-title\">Er\u00f6ffnung des Logistikzentrums Leonding<\/h2><div class=\"fusion-post-content-container\"><p>ur Sicherstellung der erfolgreichen Realisierung der langfristigen strategischen Ausrichtung der POLOPLAST wurde 2008 ein signifikanter Ausbau der Infrastruktur realisiert. Aktuell wurde am Standort in Leonding ein Logistikzentrum mit ca. 6500 m\u00b2 f\u00fcr 12.000 Palettenstellpl\u00e4tze errichtet, welches im Juni 2008 in Betrieb genommen wurde. Dieses beinhaltet auch eine \u00fcberdachte &#8220;Drive-In&#8221; Kommissionier- und Beladezone, in der bis zu vier LKW-Z\u00fcge gleichzeitig abgefertigt werden k\u00f6nnen. Durch Inbetriebnahme des neuen Logistikzentrums kann die Produktionskapazit\u00e4t durch die frei werdenden bisherigen Lagerhallen deutlich erweitert werden. Die Erweiterung der Infrastruktur ist eine Investition f\u00fcr die Zukunft.

The POLO-ECO plus marked the introduction of the first multi-layer sewage pipe for larger applications. The top coat made from polypropylene acts as a protection from damage to the surface. The middle layer is made from mineral-reinforced, highly crystalline polypropylene and possesses the formidable properties of POLO-ECO plus. It guarantees enormous resistance, firmness and stiffness while being extremely tough and can therefore be very safely applied even under high stress. The inner layer displays an extremely high resistance to chemicals in the pH-range of 1 \u2013 13, as well as a low roughness, thus allowing for optimum draining behaviour. A high abrasion fastness and impact strength round off the unique qualities of the inner layer.

The objective was to sell high-quality construction materials under a joint umbrella trademark. The managing directors Dieter Kern from Wietersdorf (left in the photograph) and Friedrich Schmid from Wopfinger (right in the photograph) thus brought together the strong points of both enterprises; i.e. cement and insulating plasters on the one hand, and lime and machine-applied plasters on the other. This is how the foundation of a new European trademark was laid. After the fall of the Iron Curtain, 1991 saw the founding of &#8220;Baumit Kft&#8221;. In Hungary, a first step was made in an easterly direction. 1994 Baumit also started to conquer Austria\u2019s southern neighbourhood in the form of Slovenia, Croatia and Italy.

The investment made here was some 35 million Austrian schillings (the equivalent of 2.5 million euros) and involved a 40-metre-high mixing tower. Originally, 37 silos (1,540cm) were at our disposal where binders, aggregates and additives were stored. An extension by 12 silos (600cm) was envisaged right from the beginning. The materials were transported to the mixer via dosing screws to up to four weighing units. Light aggregates, such as perlites or polystyrol were added with the help of separate volumetric dosage facilities. The ready-mixed material was then either blown directly into the transport silos or transported to two bagging machines via a closed conveyor belt system. After being filled, the bags were taken over the transport route to a fully automatic palleting facility, and from there via forklifts to the dispatch warehouse.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-clearfix\"><\/div><\/div>\n<\/article>\n<\/div><h4 class=\"fusion-timeline-date\" style=\"background-color:var(--awb-color7);\">1984<\/h4><div class=\"fusion-collapse-month\"><article id=\"blog-1-post-13556\" style=\"border-color:var(--awb-color7);\" class=\"fusion-post-timeline fusion-clearfix fusion-right-column post-13556 post type-post status-publish format-standard has-post-thumbnail hentry category-history\">\n<div class=\"fusion-post-wrapper\" style=\"background-color:rgba(255,255,255,1);\">\n\n\t\t\t<div class=\"fusion-flexslider flexslider fusion-flexslider-loading fusion-post-slideshow\" style=\"border-color:var(--awb-color7);\">\n\t\t<ul class=\"slides\">\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li><div  class=\"fusion-image-wrapper\" aria-haspopup=\"true\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.wietersdorfer.com\/en\/1984-die-liaison-fuehrt-zur-vermaehlung-es-kommt-zum-joint-venture-mit-hobas\/\" aria-label=\"After a period of engagement, the marriage followed: a joint venture with HOBAS was the result.\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"490\" height=\"368\" src=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1984\/01\/1984.jpg\" class=\"attachment-full size-full wp-post-image\" alt=\"\" srcset=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1984\/01\/1984-200x150.jpg 200w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1984\/01\/1984-400x300.jpg 400w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1984\/01\/1984.jpg 490w\" sizes=\"(max-width: 1024px) 100vw, (max-width: 640px) 100vw, 40vw\" \/>\t\t\t<\/a>\n\t\t\t\t\t\t\t<\/div>\n<\/li>\n\t\t\t\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/ul>\n\t<\/div>\n\t<div class=\"fusion-post-content-wrapper\" style=\"padding:30px 25px 20px 25px;\"><div class=\"fusion-post-content post-content\"><div class=\"fusion-timeline-circle\" style=\"background-color:var(--awb-color7);\"><\/div><div class=\"fusion-timeline-arrow\" style=\"color:var(--awb-color7);\"><\/div><h2 class=\"blog-shortcode-post-title entry-title\">After a period of engagement, the marriage followed: a joint venture with HOBAS was the result.<\/h2><div class=\"fusion-post-content-container\"><p>The management in Wietersdorf realised the potential of CC-GRP (centrifugally cast glass fibre reinforced plastics) Pipes and strove to establish a legally binding business with HOBAS.

All the products were made from the volcanic rock perlite. In this process, perlite is expanded at higher temperatures and its volume increased by factors of 15 to 20 while, at the same time, intensifying its thermal insulation properties. In the late 70s, polystyrol was added to the plasters as an alternative to perlite, and a plaster called ThermoExtra Putz was born and introduced to the market. This, again, meant an improvement in thermal insulation behaviour, but on the other hand some of the pressure resistance was lost. As the fa\u00e7ade insulating slabs appeared, the heyday of insulation plasters and mortars suddenly came to an end.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-clearfix\"><\/div><\/div>\n<\/article>\n<\/div><h4 class=\"fusion-timeline-date\" style=\"background-color:var(--awb-color7);\">1967<\/h4><div class=\"fusion-collapse-month\"><article id=\"blog-1-post-13576\" style=\"border-color:var(--awb-color7);\" class=\"fusion-post-timeline fusion-clearfix fusion-left-column post-13576 post type-post status-publish format-standard has-post-thumbnail hentry category-history\">\n<div class=\"fusion-post-wrapper\" style=\"background-color:rgba(255,255,255,1);\">\n\n\t\t\t<div class=\"fusion-flexslider flexslider fusion-flexslider-loading fusion-post-slideshow\" style=\"border-color:var(--awb-color7);\">\n\t\t<ul class=\"slides\">\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li><div  class=\"fusion-image-wrapper\" aria-haspopup=\"true\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.wietersdorfer.com\/en\/allocation-of-the-new-and-present-name-salonit-anhovo\/\" aria-label=\"Allocation of the new and present name &#8220;Salonit Anhovo&#8221;\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"490\" height=\"368\" src=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1967\/01\/1967.jpg\" class=\"attachment-full size-full wp-post-image\" alt=\"\" srcset=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1967\/01\/1967-200x150.jpg 200w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1967\/01\/1967-400x300.jpg 400w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1967\/01\/1967.jpg 490w\" sizes=\"(max-width: 1024px) 100vw, (max-width: 640px) 100vw, 40vw\" \/>\t\t\t<\/a>\n\t\t\t\t\t\t\t<\/div>\n<\/li>\n\t\t\t\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/ul>\n\t<\/div>\n\t<div class=\"fusion-post-content-wrapper\" style=\"padding:30px 25px 20px 25px;\"><div class=\"fusion-post-content post-content\"><div class=\"fusion-timeline-circle\" style=\"background-color:var(--awb-color7);\"><\/div><div class=\"fusion-timeline-arrow\" style=\"color:var(--awb-color7);\"><\/div><h2 class=\"blog-shortcode-post-title entry-title\">Allocation of the new and present name &#8220;Salonit Anhovo&#8221;<\/h2><div class=\"fusion-post-content-container\"><p>In 1967, the old name of the cement works &#8220;Kombinat 15.

Not only was the first kiln of its kind now almost thirty years old, it could also no longer be run economically. The capacity limits of the works had long been reached, and the time had come to set up a kiln north of the existing plant with a daily output of 1,000 tonnes of Portland cement clinker. (This meant that what was the annual production of the whole of 1913 could now be produced within half a month!). The most extraordinary feature of this kiln was its special burner which allowed for a firing by natural gas, oil and\/or coal dust, separately or mixed. Towards the late 80s, more and more surrogate fuels, such as old tyres, processed plastics, etc. started to be used. Externally, too, the kiln underwent a change; it was roofed. And it still rotates although, of course, rebuilt since and with the addition of cutting-edge technological plant components, globally speaking (basically shifting from semi-dry procedure to dry procedure with five-step cyclone pre-heater and calciner).ybr \/&gt;In this way, the specific internal energy consumption was once more able to be reduced significantly.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-clearfix\"><\/div><\/div>\n<\/article>\n<\/div><h4 class=\"fusion-timeline-date\" style=\"background-color:var(--awb-color7);\">1962<\/h4><div class=\"fusion-collapse-month\"><article id=\"blog-1-post-13584\" style=\"border-color:var(--awb-color7);\" class=\"fusion-post-timeline fusion-clearfix fusion-left-column post-13584 post type-post status-publish format-standard has-post-thumbnail hentry category-history\">\n<div class=\"fusion-post-wrapper\" style=\"background-color:rgba(255,255,255,1);\">\n\n\t\t\t<div class=\"fusion-flexslider flexslider fusion-flexslider-loading fusion-post-slideshow\" style=\"border-color:var(--awb-color7);\">\n\t\t<ul class=\"slides\">\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li><div  class=\"fusion-image-wrapper\" aria-haspopup=\"true\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.wietersdorfer.com\/en\/salonit-pioneer-in-communication\/\" aria-label=\"Salonit: pioneer in communication\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"490\" height=\"368\" src=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1962\/01\/1962-1.jpg\" class=\"attachment-full size-full wp-post-image\" alt=\"\" srcset=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1962\/01\/1962-1-200x150.jpg 200w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1962\/01\/1962-1-400x300.jpg 400w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1962\/01\/1962-1.jpg 490w\" sizes=\"(max-width: 1024px) 100vw, (max-width: 640px) 100vw, 40vw\" \/>\t\t\t<\/a>\n\t\t\t\t\t\t\t<\/div>\n<\/li>\n\t\t\t\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/ul>\n\t<\/div>\n\t<div class=\"fusion-post-content-wrapper\" style=\"padding:30px 25px 20px 25px;\"><div class=\"fusion-post-content post-content\"><div class=\"fusion-timeline-circle\" style=\"background-color:var(--awb-color7);\"><\/div><div class=\"fusion-timeline-arrow\" style=\"color:var(--awb-color7);\"><\/div><h2 class=\"blog-shortcode-post-title entry-title\">Salonit: pioneer in communication<\/h2><div class=\"fusion-post-content-container\"><p>Salonit was clearly a pioneer in terms of internal communication.

It was then that technicians of the Basel textile dyeing factory were looking for an alternative to the wooden cylinders around which the fabric was wound during the dyeing process. Splintered and coloured wood was a danger to the expensive textiles and a replacement was urgently required. The new material had to be able to be manufactured in the form of a cylinder with a circular cross section and constant outer diameter, be resistant to corrosion, have a low weight and a smooth surface to guarantee a uniform dyeing result, and moreover, it had to be economical.

The cement works that had been planned and even started before the War were completed in no time. In September 1949, cement production was taken up although the situation was not at all very economical: both the raw materials and the cement had to be ground in one and the same mill, and it was not until 1953 that a separate raw mill went into operation. In the first few years, the average output was 30,000 tonnes of cement; by 1955, the average output had already risen to some 50,000. It was only in 1958 that Alois Kern was able to purchase the plant, which was still in German hands and administered by the allied occupation forces. In 1959, a settlement was reached concerning the shares in the Peggauer Zementwerke Alois Kern on the one hand, and the Wietersdorfer Zementwerke Phil. Knoch &amp; Co. on the other hand.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-clearfix\"><\/div><\/div>\n<\/article>\n<\/div><h4 class=\"fusion-timeline-date\" style=\"background-color:var(--awb-color7);\">1939<\/h4><div class=\"fusion-collapse-month\"><article id=\"blog-1-post-13610\" style=\"border-color:var(--awb-color7);\" class=\"fusion-post-timeline fusion-clearfix fusion-left-column post-13610 post type-post status-publish format-standard has-post-thumbnail hentry category-history\">\n<div class=\"fusion-post-wrapper\" style=\"background-color:rgba(255,255,255,1);\">\n\n\t\t\t<div class=\"fusion-flexslider flexslider fusion-flexslider-loading fusion-post-slideshow\" style=\"border-color:var(--awb-color7);\">\n\t\t<ul class=\"slides\">\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li><div  class=\"fusion-image-wrapper\" aria-haspopup=\"true\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.wietersdorfer.com\/en\/first-rotary-kiln-of-the-so-called-lepol-system\/\" aria-label=\"First rotary kiln of the so-called Lepol system\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"490\" height=\"368\" src=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1939\/01\/1939-1.jpg\" class=\"attachment-full size-full wp-post-image\" alt=\"\" srcset=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1939\/01\/1939-1-200x150.jpg 200w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1939\/01\/1939-1-400x300.jpg 400w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1939\/01\/1939-1.jpg 490w\" sizes=\"(max-width: 1024px) 100vw, (max-width: 640px) 100vw, 40vw\" \/>\t\t\t<\/a>\n\t\t\t\t\t\t\t<\/div>\n<\/li>\n\t\t\t\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/ul>\n\t<\/div>\n\t<div class=\"fusion-post-content-wrapper\" style=\"padding:30px 25px 20px 25px;\"><div class=\"fusion-post-content post-content\"><div class=\"fusion-timeline-circle\" style=\"background-color:var(--awb-color7);\"><\/div><div class=\"fusion-timeline-arrow\" style=\"color:var(--awb-color7);\"><\/div><h2 class=\"blog-shortcode-post-title entry-title\">First rotary kiln of the so-called Lepol system<\/h2><div class=\"fusion-post-content-container\"><p>In 1931, continuously rising demands caused the company management to erect a Thiele high performance kiln with a daily capacity of approx. 100 tonnes. At the time, cement was still delivered in 200 kg barrels. However, capacities were not able to meet the demand. Therefore, Wietersdorf invested in a modern Lepol rotary kiln with a daily capacity of 200 tonnes. Just before the end of the Second World War, the capacity of the works was once more fully exploited. In 1940, the state-controlled company &#8220;Verkaufsgemeinschaft S\u00fcd-Ost&#8221; requested that Wietersdorf deliver 71,000 tonnes of cement (this equalling 355 days work at maximum capacity). Financially speaking, these were interesting orders from the point of view of the owners, but from the proceeds so-called &#8220;donations&#8221; had to be made to the Third Reich, and 18.5% war tax had to be paid on top.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-clearfix\"><\/div><\/div>\n<\/article>\n<\/div><h4 class=\"fusion-timeline-date\" style=\"background-color:var(--awb-color7);\">1931<\/h4><div class=\"fusion-collapse-month\"><article id=\"blog-1-post-13614\" style=\"border-color:var(--awb-color7);\" class=\"fusion-post-timeline fusion-clearfix fusion-right-column post-13614 post type-post status-publish format-standard has-post-thumbnail hentry category-history\">\n<div class=\"fusion-post-wrapper\" style=\"background-color:rgba(255,255,255,1);\">\n\n\t\t\t<div class=\"fusion-flexslider flexslider fusion-flexslider-loading fusion-post-slideshow\" style=\"border-color:var(--awb-color7);\">\n\t\t<ul class=\"slides\">\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li><div  class=\"fusion-image-wrapper\" aria-haspopup=\"true\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.wietersdorfer.com\/en\/start-of-the-pipe-production\/\" aria-label=\"Start of the pipe production\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"490\" height=\"368\" src=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1931\/01\/1931-1.jpg\" class=\"attachment-full size-full wp-post-image\" alt=\"\" srcset=\"https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1931\/01\/1931-1-200x150.jpg 200w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1931\/01\/1931-1-400x300.jpg 400w, https:\/\/www.wietersdorfer.com\/wp-content\/uploads\/1931\/01\/1931-1.jpg 490w\" sizes=\"(max-width: 1024px) 100vw, (max-width: 640px) 100vw, 40vw\" \/>\t\t\t<\/a>\n\t\t\t\t\t\t\t<\/div>\n<\/li>\n\t\t\t\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/ul>\n\t<\/div>\n\t<div class=\"fusion-post-content-wrapper\" style=\"padding:30px 25px 20px 25px;\"><div class=\"fusion-post-content post-content\"><div class=\"fusion-timeline-circle\" style=\"background-color:var(--awb-color7);\"><\/div><div class=\"fusion-timeline-arrow\" style=\"color:var(--awb-color7);\"><\/div><h2 class=\"blog-shortcode-post-title entry-title\">Start of the pipe production<\/h2><div class=\"fusion-post-content-container\"><p>In 1931 the Wietersdorfer Zement- und Durit-Werke Phil.

Surprisingly, first signs of environmentally-conscious thinking were experienced even then in that the authority ruled that the outgoing water from the existing sewage plant &#8220;should be once more clarified from now on&#8221;.

In 1915, the works was taken over by the Knoch brothers who started the production of roof slates on the so-called &#8220;Prosig&#8221; machine. In the war years, cement was crucial for the building of emplacements, and for this reason a considerable share of the production was sent to Tarvisio in Italy.
