The product of large volume, large amount of price concessions. The new upgrade of green special drainage board, roof greening is your better choice.
Product Name: roof greening special drainage board
Function: drainage, water storage, heat insulation, anti permeability, compressive, root
Each piece of specification：500mm*500*25mm, 4 = 1 square
Texture of material：Modification of high molecular weight HDPE, glass fiber, nano oxide,
Construction of drainage plate
A. tapered lug (hollow cylindrical porous) plastic floor, composed of high impact polystyrene (HIPS). The cone boss (or the top surface of the porous hollow cylinder) bonding a filter layer of geotextile, to prevent the soil particles through, so as to avoid blocking the channel smooth drainage channel.
The advantages of B. 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. Load and now use the drainage board to replace the pebble filter layer to drainage time and labor saving and energy saving, investment, and reduce the building.
C. drainage board function
Has an important role in good drainage system construction period on civil engineering structures and the normal use and life. Drainage plate and porous HW drain infiltration pipe form an effective drainage system, porous drainage plate and geotextile cylinder is composed of a drainage system, thus forming a system with water seepage, water storage and drainage function.
Application of D. drainage board
Garden Project: the garage roof greening, Roof garden, football, golf, beach engineering;
Municipal Engineering: road subgrade, subway tunnel;
Construction: building foundation above or below, the basement outer wall, roof waterproof and insulation;
Traffic engineering, highway, railway roadbed, dam and slope protection layer;
The principle of green roof drainage board
Has an important role in good drainage system construction period on civil engineering structures and the normal use and life.LDDrainage plate and porous plate water infiltration pipe form an effective drainage system, porous drainage plate and geotextile cylinder is composed of a drainage system, thus forming a has the water seepage, water storage and drainage system, play the following roles:
Very smooth drainage:
Drainage is one of the most important functions of roof greening, water discharge in a timely manner, the roof will not leak. Green roof drainage board will be separated from the soil and roof overhead,The surface mesh structureTo avoid the geotextile, subsidence, drainage.
Overhead storage box drain plate isolation layer design, useThe air layer heat partitionSo, the temperature can not be transmitted to the roof, so as to reduce the indoor temperature.
The roof greening soil layer is generally thin, high temperature, moisture evaporates quickly, therefore a unique water storage tank design, to ensure the surplus water storage in the groove, which does not increase the load of the roof, and can supply the plant.
Root control and root resistance:
In the absence of any root can grow in the air medium. Therefore, when the root across the water storage and drainage plate without any air medium belowIsolation layerWhen not down growth, and will be separated in the soil in the horizontalHair root(air seedling root control principle). Can control the root on the roof and waterproof layer damage, and promote plantHair rootDeveloped stronger vitality.
Very high compressive strength and break:
The water storage and drainage plate by injection molding, sheet thickness, compressive strength, no longer need to worry about the construction will trample on the flattening.
Green roof drainage board below the overhead of 2 - 3cmAir layerThat makes the soil more breathable, conducive to plant growth.
Construction and demolition convenient.
If you regret in some places has been green, now want to clean out any where necessary to water storage and drainage plate removed, does not affect the other green area.
