For the construction of the ErfGoedFloor we make use of local stone types such as lava, granite, gravel and crushed stone. These materials are analyzed thoroughly beforehand in our laboratory for shape, water permeability, moisture absorption, drying and other factors. We choose materials with the greatest care.
For optimal operation of the ErfGoedFloor, the use of a stabilization mat is of great importance. This mat protects the membrane and also ensures perfectly even distribution of water within the floor.
