Drainage board plastic drainage board is made of polystyrene (HIPS) or polyethylene (HDPE) as the raw material plastic bottom plate through stamping into a conical protrusion or stiffener bump (or hollow cylindrical porous) formed, after continuous innovation and research and development, the raw material has been greatly improved and changed, is now made of polyvinyl chloride (PVC) as the raw material pressing, compressive strength and overall flatness has been greatly improved, the width is 1-3 meters, the length is 10-15 meters or 20 meters (can be customized according to customer needs).
Because the raw materials of the drainage board are high-impact polystyrene and high-density polyethylene, which are refractory engineering plastics, they can be placed in the building interlayer, which can effectively resist aging and can achieve the same life as the structure. It is used in the roof of underground engineering or roof greening, with high compressive strength and light loadIt can effectively protect structures and waterproof layers, and resist all kinds of acids and alkalis in the soil and plant root thorns. When backfilling the exterior wall of the basement, it protects the building and the waterproofing layer from damage. Laboratory data show that polyethylene and polyvinyl chloride drainage boards can effectively reduce indoor noise of 14 dB and 500Hz, and have obvious construction sound insulation functionsWhen used on the ground or wall, it can also play a good role in ventilation and moisture-proofing.
Compared with the conventional process, the drainage board is compounded with geotextiles, which has a variety of functions such as drainage, waterproofing, breathability, moisturizing, and root separationUsed for thermal insulation flat roof or underground engineering floor, the multiple fulcrums of the drainage board form a gap between the building surface layer and the structural layer, and have the functions of moisture insulation, drainage, and heat preservationThere are large and small fulcrums on the edge of the product, which can be overlapped with each other, and even if there is more leakage, it can be discharged in time. It is very convenient for construction and transportation.
