 Drainage Board for the past few years, a water impermeable material listed, the introduction of Germany, Japan and other countries of advanced production technology and design, encouraging scientific and technological achievements to come. In 2003 the domestic first in Beijing, Shanghai and other large urban real estate development and construction of the garage in the first test application. Drain material is generally high-density polyethylene (HDPE) and high density polystyrene, polypropylene and other synthetic materials, polymer chemistry, polymer chemistry because of the physical and chemical properties of materials, determine the drainage board products have superior anti- tensile strength, high compressive effect (load to 35t / m); flexibility and good physical properties, and the other materials in the drainage board products of antioxidants, anti-aging agent, makes drainage board decomposition period (use period) to more than 100 years, with the sunscreen waterproof, high temperature, low temperature function; following sheet resistance can also play the root of the results, some developers (Party) design construction units need to use every root plate, where I want to say is, it is absolutely necessary, it can be said, to spend every root is a waste of financial and material resources only.
