Famous Storage and drainage board for underground garage roof Exporter, Exporters

The water storage and drainage board is made of high-density polyethylene (HDPE) or polypropylene (PP), which is formed by heating, pressing and shaping. It is a lightweight board that can create a drainage channel with a certain three-dimensional space support stiffness and can also store water.

Product Description

The water storage and drainage board has two comprehensive functions: water storage and drainage. The board has the characteristic of extremely high spatial stiffness, and its compressive strength is significantly better than similar products. It can withstand high compressive loads of over 400Kpa, and can also withstand extreme loads caused by mechanical compaction during the backfilling process of planting roof.

Common Applications
Used for roof greening, underground roof panel greening, urban squares, golf courses, sports fields, sewage treatment plants, public building greening, square greening, and road greening projects within the park.
Installation & Construction Guidelines
1
When used in flower ponds, flower slots and flower beds in gardens, conventional materials are directly replaced by water storage plates and filter geotextiles (such as filter layers composed of pottery, pebbles or shells).
2
For the greening of the hard interface such as the new and old roof or the roof of underground engineering, before laying the storage and drainage board, clean the debris on the site, set the waterproof layer according to the requirements of the design drawings, and then use cement mortar to slope, so that the surface has no obvious convex and convex, the storage and drainage board is discharged in an orderly manner, and there is no need to set a blind drainage ditch within the laying scope.
3
When it is used to make a sandwich board of a building, the storage and drainage board is laid on the roof concrete board, and a single wall is built outside the storage and drainage board, or concrete is used to protect it, so that the underground seepage water flows into the blind ditch and the water collection pit through the overhead space of the drainage board.
4
The storage and drainage board is spliced around each other, and the gap when laying is used as the lower drainage channel, and the geotextile filtering and moisturizing layer on it needs to be lapped well when laying.
5
After the storage and drainage board is laid, the next process can be carried out to lay the filter geotextile and matrix layer as soon as possible to prevent the soil, cement and yellow sand from blocking the pore or entering the water storage, sink and drainage channel of the storage and drainage board. In order to ensure that the storage and drainage board gives full play to its role, the operation board can be laid on the filter geotextile to facilitate the greening construction.
Frequently Asked Questions
What are the primary functions of the water storage and drainage board?
The board has dual comprehensive functions: storing water to provide moisture for plant growth and efficiently draining excess water to prevent waterlogging.
How strong is the board under heavy pressure?
The board features exceptionally high spatial stiffness and compressive strength. It is built to withstand high compressive loads of over 400Kpa, making it resistant to extreme loads caused by mechanical compaction during roof backfilling.
Where is this drainage board typically applied?
It is widely used in greening projects including roof and underground roof greening, urban squares, golf courses, sports fields, sewage treatment plants, public buildings, and park pathways.
Do I need to install blind drainage ditches when laying the board on roof surfaces?
No. When laying the storage and drainage boards in an orderly manner over a sloped cement mortar base, there is no need to set a blind drainage ditch within the laying scope.
What precautions should be taken after laying the boards?
Once laid, you should proceed to install the filter geotextile and matrix layer as soon as possible. This prevents soil, cement, or yellow sand from blocking the drainage channels and pores.
