Ⅰ.Product Introduction
The drainage board is made of polystyrene (HIPS) or polyethylene (HDPE) plastic bottom board which is stamped into a conical protuberant platform or a raised point of stiffener rib (or hollow cylindrical porous). The width is 3 meters and the length is 10 meters or 15 meters. The drainage board is divided into two series of rolls and boards. The rolls are divided into three types: "hot melt", "lap joint" and "self-adhesion". The special method is used to press the plastic board out of the closed convex cylindrical shell, forming a concave-convex membrane. And the shell is continuous, and has a three-dimensional space and a certain supporting height. In the processing and production of the edge, butyl rubber strips are hotly bonded, and the top of the shell is covered with the filter layer of the geotextiles . The product is used for seepage, dewatering, drainage and water storage. It is also known as self-adhesive PE drainage board, drainage and dewatering board, drainage protection board, water filter board, plastic concave-convex drainage board, plastic sandwich board.
Ⅱ.Product Classification
Common drainage boards in construction include: self-adhesive PE drainage board, plastic drainage board, storage-drainage board, rolls drainage board, anti-seepage drainage board, composite drainage board, three-dimensional drainage board and schistic drainage board, etc.
Ⅲ.Product Features
Water conductivity and drainage
The anti-drainage protection board has a concave-convex hollow rib structure, which can quickly and effectively discharge rainwater, greatly reduce or even eliminate the hydrostatic pressure of the waterproof layer. The active water-conducting principle can achieve the effect of active waterproofing.
Waterproofing
The polyethylene (HDPE) waterproof-drainage protection board material itself is a good waterproof material. The waterproof board is a good auxiliary waterproof material by adopting a reliable connection.
Protection and Defense
The waterproof-drainage protection board can effectively protect the structures and the waterproofing layer, and resist various types of acid and alkali and plant root thorns in the soil. It can protect buildings and waterproofing layers from damage when backfilling the underground outdoor wall.
Sound insulation, ventilation and moisture proof function
Laboratory data show that polyethylene (HDPE) waterproof-drainage protection board can effectively reduce indoor noise of 14 decibels and 500Hz, and has obvious noise reduction and sound insulation. The waterproof-water deflection board can also have very good ventilated moistureproof action when used on the ground or wall.
Ⅳ. Applications
Greening project: garage roof greening, roof garden, vertical greening, inclined roof greening, football field, golf course.
Municipal project: airports, roadbeds, subways, tunnels, landfills.
Construction project: the upper or lower layer of the building foundation, the inner and outer wall, baseboard of the basement,the top board and anti-seepage and thermal-protective coating of roofing.
Irrigation works: waterproofing and seepage prevention of reservoir, impounding reservoir and artificial lake.
Traffic project: roads, railway roadbeds, dams and slope protection layer.
