Zhaoyang sheet drainage board

  Compressive strength: 580kpa, which can bear the load of planting soil and greening tree system above 3
0m
Weather resistance: it can be used normally at + 40 ℃ - 60 ℃

Aging resistant service life: the material composition is modified HDPE, which is a difficult to decompose material for more than 50 years

Color: black, grass green, ink green, white
It can be customized according to customer requirements

Product application: roof garden, garage roof, golf course, public buildings, squares, park roads and other greening projects

Advantages of the product: uniform drainage, reserved greening water, large water storage, regulating water supply, heat preservation and moisture conservation, water saving and energy saving, good soil permeability, conducive to the absorption of oxygen and water by plants, large bearing capacity, light load, simple and light construction, durability and environmental protection

The water storage and drainage board is made of HDPE through heating and pressure forming to form a drainage channel, which can not only create three-dimensional space support stiffness, but also a light board for water storage
The traditional drainage method is to use bricks and stones as the filter layer and pebbles or gravel as the water treatment layer to discharge the water to the location
Replacing pebble water treatment layer with drainage board can save time and reduce the load of buildings
The drainage board and porous drainage pipe form an effective drainage system, and the cylindrical porous drainage board and geotextile also form a drainage system, so as to form a system with water seepage, water storage and drainage functions

If the bearing capacity fails to meet the standard, or there is void at the bottom of the cement concrete pavement, it shall be strengthened, and the joints and cracks of the cement concrete pavement shall be cleaned and filled in advance
Local relaxation, potholes and diffuse cracks on the original pavement and base course surface shall be repaired and filled in advance to keep the surface in good condition
The original pavement surface shall be washed clean to prevent dust, loose particles and sundries
The drainage board has good flexibility and strong adaptability to soil deformation
With good durability and anti-aging formula, it has stable performance, UV resistance, high temperature resistance, corrosion resistance and other characteristics
The proportion of drainage board is light, and the construction and installation is very convenient
Before paving PVC drainage board, the bearing capacity of pavement is evaluated, and the construction efficiency is greatly accelerated

It has two-way functions of rainwater drainage and collection, with large water storage and drainage
Combined with geotextile, it can avoid the fine particle matrix blocking the drainage channel and maintain smooth drainage and air circulation, so as to form a complete and new combined filtration storage and drainage system, which is a good substitute for traditional water filtering materials
Water storage index: normal water storage per square meter ＞ 4kg
