HDPE composite dimple geomembrane cover geotextile drainage
Tinhy composite drainage board is produced from HDPE with high impact resistance and pressure resistance. Plastic Drainage Board can resist long-term high pressure, and will not generate deformation.
The long-term pressure resistance not only can resist weight of concrete bottom plate and its load, but also can bear unavoidable outside pressure and impact force during construction, for example, vehicle, worker stepping, concrete pouring impact force, etc. Drainage protection board integrates waterproof and drainage, solves relation between waterproof and drainage successfully, and is better and more reliable than traditional stone pottery particle drainage and other filter layers both in drainage function and economic benefit.
Brief Introduction of Dimple Drainage Board
Drainage Board adopt high-density polyethylene as raw material, using high pressure injection molding process
to suppress a hole-shaped lump, with three-dimensional space and certain support height. It is popularly
applied in roof greening, subway tunnels, water reservoir seepage, vertical green and many other areas.
Features
Drainage board has the special structure, which can quickly and effectively derived rain and greatly reduce or even eliminate the waterproof layer of hydrostatic pressure, also can achieve active waterproof effect through this initiative guide water principle. Pondage and drainage plate material itself is a kind of very good waterproof materials. By using reliable down slope of overlapped method, it is to become a kind of very good auxiliary waterproof material. Pondage and drainage plate can effectively reduce the indoor noise. Drainage shielding panels have very good ventilation moisture proof effect to use on the ground or metope.
The plastic storage and drainage plate is a type of green roof systems which are drained by a special molding plastic sheets. Water is retained within dimple on the upper sides of the drainage plates; excess water spills over the edges of the plates and is carried off the roof.
The plastic storage and drainage plates are made from HDPE(high-density polyethylene), using high pressure to inject plastic to form hole-lump-shaped shell, with stereo space and support level; in the top of the shell, covering with non-woven as filtering level for water percolation, water storage and water drainage.
