Industrial bulk floors, which are produced on a special polyurethane basis, have the most optimal combinations of elasticity, attractive type, as well as hardness. These properties allow such a design to be very important elements during laying in rooms in which floors are constantly observed and great mobility. Investigation floors are widely used in those rooms in which temperature fluctuations are observed, as well as at production facilities that are not heated. Such floors can better tolerate the effects from strict abrasive substances.
