136 * 6868 * 8676 plastic sandwich board "is a" blocking + row + blocking "mode waterproofing and drainage materials, green roofs, roof insulation, the basement roof waterproofing methods to ensure that project never leak. Compared with the traditional layers of waterproof material + pebble ", this product has engineering leakage, the construction is simple and convenient, reduce roof loads, energy saving, heat, noise, water storage project cost savings, improve project quality, to eliminate , moisture and other features. mainly used for: green roofs, flat roofs, underground engineering 136 * 6868 * 8676 drainage board products originated in Europe, initially based on the needs of the green roof drainage, ventilation function, because the planted roof is an artificial to create planting ecological systems, roofing set impervious gas waterproof layer, and the cultivation of the soil is relatively thin, it is difficult to meet the plant growth breathable, water supply and drainage requirements. expanding product range with the drainage board, and use Extension , it was discovered that a the drainage board product is widely used, especially its flexible protection project to be widely adopted worldwide, drainage board material from the product formally divided into two categories: 136 * 6868 * 8676 ● filamentous superimposed. similar to the "instant noodles", because the laminated body having a gap, it can allow the water, the gas in the inner flow drainage is a function of a single material, only be used as a drainage layer. ● continuous sheet irregularity pressure type. This is a Class stiffness of the plastic sheet to suppress the irregularity housing, the use of the formation of large geometry space is formed supported on a continuous membrane to create a drainage, breathability space. 136 * 6868 * 8676 is a continuous sheet (web ), this form of drainage board with many special features, such as additional waterproof, flexible protection functions, additional isolation insulation function, vibration isolation function, noise function of the two different forms of drainage board products The main differences are the functional differences as a planted roof drainage board. lack of a continuous sheet bump pressure can save plant roots puncture-resistant protective layer, the default flexible waterproof layer of rigid protective material (waterproof layer concrete protective layer), which greatly simplifies building facade parts of the structure of the default winter heaving buffer, etc. Contact: Zhou Tel 13668688676 Website http://www.taldjc.com
