Roof leak is the main and big trouble for a house or building, today we get a long and permanent solution of roof waterproofing, with our OUMINGLANG SUPER DPS, which spray and penetrating inside the rooftop concrete structure to form a thick matrix crystalline layer from 50-500mm. And it is not just a thick membranes on skin, our core material still inside concrete and if water appear after 10-15year, it will combine and crystallize again with water. So there is the concept structured self-healed waterproofing, maybe it is a best patch for concrete.
