Presenting a patented technology, as well as house and building projects, the three-layer wall elements of which are made of concrete and insulating filler. The form of the building's wall elements is brought to the construction site and vertically filled with concrete from local suppliers. This drastically reduces CO2 emissions during transportation and does not limit distances, as concrete form the maximum mass of a long-lasting product. The construction of the reinforced structure in the form is easily adapted according to the energy A++ and load requirements of the building. Internal walls and facade monolith layer do not require additional costs for plastering. "L"-shaped elements are particularly stable, look natural, and are ready for use immediately after multiple dismantling of the formwork. The biggest advantage is mobility and export possibilities - wherever you can fill the mold with concrete.
