Rollmats are prefabricated to the correct dimensions, delivered to the building site on schedule and installed quickly with minimum effort by simply unrolling a few reinforcement elements. The installation time is shortened by 80 to 90 %. The rollmat is already standard in many countries. While rollmats have been used successfully in Scandinavia for a long time, the development is sluggish in German-speaking countries. That is actually difficult to understand because the benefits are clear and convincing. In addition to the unbeatable, easy and fast installation, up to 40 % of expensive reinforcing steel is saved, because rollmats can be tailor-made with different rod diameters, rod spacing and penetrations. In addition to the energy-saving, ergonomic procedure on the building site, significantly greater installation quality is achieved due to easy placement and exact rod position.
