The newly upgraded special water storage and drainage board is a better choice for roof greening.
Product Name: special water storage and drainage board for roof greening
Function: drainage, water storage, heat insulation, root protection, air permeability, compression
Unit price: 3.50 yuan / piece, each piece of standard 500mm*500mm, 4 pieces = 1 square
Height: 25mm, material: HDPE
Structure of A. drainage plate
The conical bottom (or hollow cylindrical porous) plastic bottom plate is made of high impact polystyreneHIPSMade into. The top of the cone (or the hollow cylindrical porous) is glued with a filter layer geotextile to prevent the soil particles passing through, thus avoiding the blockage of the channel, and the drainage of the tunnel is smooth.
BThe advantages of drainage board
Traditional drainage system using brick tile as a filter layer, the use of more pebbles or gravel as the filter layer, the water is drained to the designated place. Now, instead of pebbles, drainage plates are used to drain water, saving time, labor and energy, saving investment, and reducing the load on buildings.
The function of C. drainage board
A good drainage system plays an important role in the construction period of civil works and the normal use and service life of structures.HWThe drainage plate and the porous seepage pipe form an effective drainage system, and the cylindrical long and short drainage plate and geotextile also form a drainage system, thus forming a system with seepage, water storage and drainage function.
Application of D. drainage board
Landscape engineering: garage roof greening, Roof garden, football field, golf course, bathing project;
Municipal Engineering: road subgrade, subway tunnel;
Building engineering: building foundation of the upper or lower layer, underground indoor and outdoor walls, roofing seepage and insulation layer;Traffic engineering: highway, railway subgrade, embankment and slope protection layer;
★A good drainage system plays an important role in the construction period of civil works and the normal use and service life of structures.LDThe drainage plate of the drainage plate and the porous seepage pipe form an effective drainage system, and the cylindrical long and short drainage plate and geotextile also form a drainage system, thus forming a system with seepage, water storage and drainage function,Play the following role:
Very smooth drainage:
Drainage is one of the most important functions of roof greening. When the water is discharged in time, the roof will not leak. Roof greening and drainage board separates the soil from the roof,Surface network structureThe geotextile is avoided and the drainage is smooth.
Design and application of overhead isolation layer of square storage and drainage plateThe air layer partitions the heatThe temperature can not be transmitted to the roof so as to reduce the indoor temperature.
Roof greening soil layer is generally thin, high temperature, rapid evaporation of water, so the unique storage tank design, to ensure that excess water stored in the groove, neither increase roof load, but also for plant absorption.
Root control and root resistance:
Roots can't grow in the air without any medium. So when the roots meet the drain, there's no media airIsolation layerIt can't grow downward, but it will cross over in the soil layerHair root(air seedling root control principle). It not only controls the damage of root system to roof and waterproof layer, but also promotes the plantHair rootDeveloped, stronger vitality.
* super compression break:
The drainage plate adopts injection molding technology, the plate is thick, the compression resistance is super, and there is no need to worry about the construction will be crushed and squashed.
The roof is under the water storage and drainage board2－3cmOverheadAir layerMake the soil more breathable, conducive to plant growth.
Construction and demolition convenient.
If you regret that some places have been greening, and now want to clean out, you can easily at any time need to place the drainage plate demolition, does not affect other green areas
