Our 8mm Pre Cut Rubber Rolls can be used as flooring in offices and has. Our Rubber flooring is meant to handle heavy weight equipment, so desks, chairs, filing cabinets and chairs will not affect the floor. If you were to spill anything on the floor, as long as it's cleaned in a timely fashion, there would be no issues with cleaning it up. Our rubber flooring is water resistant, and most liquids will pool up on top of the flooring. Rubber is naturally mold and mildew resistant, so the only time you will see any growth would be from organic matter being left on the floor for a long period.
