Product Description
HDPE waterproofing drainage sheet for roof garden
The Dimple Drainage Sheet 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 Hdpe Dimple Drainage Sheet 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.
Product Description
"Tinhy" HDPE drainage board has the good performance in water discharging and storing.
The special design could provide the oxygen for plants.
The board could be interconnected at your own disposal.
It is an indispensable basic material in the gardening project.
It has been widely used in roof green, underground parking lot, urban plaza, golf field, sport field, partition,wastewater treatment, plant, balcony and so on.

Drainage materials
1, Tianhai drainage board is produced from HDPE with high impact resistance and pressure resistance, can resist long-term high pressure, and will not generate deformation.
2,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.
3, 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.
4,It can keep bottom plate no deformation for long term, so original drainage quantity can be kept. Application of filter layer earthwork fabric on bottom plate is to ensure drainage channel isn't blocked by foreign object, for example, backfilling particle or concrete.
5,It is widely used in waterproof and drainage of roof garden, outdoor garage top plate
