Our company was established many years has excellent technical level force, the latest product of automation equipment in geotechnical materials industry, improve sales and service network, will provide customers with products and services for the new and old customers. Drainage board is made of polystyrene (HIPS), or made of polyethylene plastic floor after punching cone penetration units (or hollow cylindrical porous) from the top surface of the plastic cone projections access layer of filter geotextile to prevent soil particles through, so as to avoid blocking the drainage channel, making smooth drainage. The traditional use of brick tile drainage as a guide filter layer, using more pebbles or gravel as a drainage layer, the water discharged to the designated place. Now replace the drainage layer of pebbles with a drain to drain is saving time, effort and energy saving investment waterproof blanket, but also reduce the load of anti-drain buildings have hollow stud bump structure can effectively export clapper rain, greatly reduce or even eliminate the hydrostatic pressure of the waterproof layer, the water guiding principle in this initiative can achieve active waterproofing effect. The company made goods around the country, factory direct supplier obvious price advantage, the price is lower than local manufacturers! Sincerely extensive cooperation with our friends, draw up a grand blueprint! Sales Hotline [13287601199]
