Who we are - Our company


Kappema was founded in 2005 by 3 individuals who, through a combination of innovation and thorough knowledge of the product, wanted to explore new paths in the precast concrete component industry. In particular, these included the development of different products to improve precast components, including new areas in production technology.


Main shareholder of Kappema is today Oberndorfer Precast from Gunskirchen in Austria. One of the biggest precast producer in Europe.


The development of a mobile production facility for concrete components, for use on construction sites in growth areas and/or inaccessible areas, was an early milestone. This mobile production unit, KAP-CFP (Concrete Field Production) remains a key component of the Kappema range.


Development on an optimised wall connector for insulated double walls began in 2006 in response to requirements concerning heat insulation and climate change. One idea and several attempts later, the patented KAP-ISO-Wave in glass fibre reinforced plastic arrived on the market. Kappema won the 2007 Research and Cooperation award from ACR. Word got around very fast about this product and its outstanding workmanship and heat insulation qualities so further development was the logical next step.


The KAP-Steel-Wave was developed as an alternative to standard double wall connectors. Because this was a completely new approach, the necessary tests and calculations required to gain approval were very extensive. However, the patented KAP-Steel-Wave officially received approval from DIBT in Berlin as a wall connector in 2011. Meanwhile the KAP-Steel-Wave has an european approval since 2015, which allows you to use the KAP-Steel-Wave in all member countries of EOTA. Kappema was one of the first companies in precast industry making such a step. The ETA is above all natinal approval. on top the KAP-Steel-Wave is tested for the use in seismic zones according the Eurocode 8 and TEC.


Development on the KAP-Steel-Wave brings out the KAP-Thermo-Wave which is used in insulated wall elements. It is already tested for the use in sandwich wall elements as well as insulated double wall elements. At the moment the KAP-Thermo-Wave is applied for the ETA to be used all over Europe. The KAP-Thermo-Wave will be the most economical connection on the market for insulated precast elements.


The latest product to join the Kappema family is the stainless steel perforated plate formwork upright. A new way of easily framing cavities in double walls and reducing the amount of work on the construction site. Depending on the material it is called for stainless steel KAP-ELO and for galvanized steel KAP-ZiLO. To simplify the handling in production, Kappema created magnetic holders which can be designed for every production in a perfect way as we use 3D printing technologie.  


Kappema will also continue to cooperate with a wide range of manufacturers throughout Europe developing products which redefine the use and applicability of precast concrete parts. Because Kappema employees come from the precast part industry and develop for the precast part industry.
