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. The plastic
storage and drainage plate also named water drainage protection
plate or water filtration plate or plastic interlayer
board. Main Advantages
1.Water drainage: Drainage plate can be used in combination with
non-woven to get rid of the rain immediately and effectively
relieve the roof’s pressure caused by the instantaneous
rainfall.
2.Water storage: Absorb and store redundant moisture leaking from
the planting layer and supply needed moisture for the plant when
the soil lacking of water to improve plant’s drought-resistance
ability.
3.Ventilation: Special design helps the plant layer to have good
air-ventilation ability at the bottom, improves ventilating
situation and ensures the oxygen demand for root.
4.Heat insulation: The storage place
for the drainage plate is at the bottom of the plant, helping the
plant to stop from the sun direct illuminating and form a cool
space, which can absorb heat from structure layer to form air
troposphere.
5.Safety: Plastic storage and drainage plate‘s light weight will
not enhance load for roof structure.
6.Environment protection: it is **0% recycling, won't cause
secondary pollution to the environment.
7.Bearing performance: Bearing strength for storage-drainage plate
can reach *0 ton per square as the highest, suitable for all kinds
of landscape on the top.
8.Low price: ultra-light weight, easy installation, quick
construction, low construction cost and simple maintenance.
