Qiqihar plastic drainage board is directly supplied by Jiahai manufacture

  Jiahai water storage and drainage board quality assurance drainage board is a high-density polymer (HDPE) geomembrane produced by extrusion method or blow out method
Through special process pressing, the membrane and shell formed by closed convex circular platform, cylindrical and spherical coronal shells are pressed on the geomembrane
It has three-dimensional space and certain support height, in which liquid and gas flow

Folding drainage
The waterproof and drainage protection board has a concave convex hollow vertical bar structure, which can quickly and effectively export rainwater and greatly reduce the hydrostatic pressure of the waterproof layer
Through this positive water guiding principle, a positive waterproof effect can be achieved

Polystyrene (HPVC) polystyrene waterproof board itself is a good waterproof material
Through reliable connection, the waterproof and drainage board has become a good auxiliary waterproof material

Folding protection
Waterproof and drainage protection board can effectively protect the structure and waterproof layer, and resist all kinds of acid and alkali in the soil and root thorns of plants
When backfilling the outer wall of the basement, the building and waterproof layer can be protected from damage

Sound insulation, ventilation and moisture-proof functions:
Laboratory data show that PVC waterproof and drainage protection board can effectively reduce indoor 14 dB and 500Hz noise, and has obvious noise reduction and sound insulation function
When using floor or wall, PVC waterproof water guide plate can also play a good role in ventilation and moisture-proof

Scope of application
Greening works: garage roof greening, roof garden, vertical greening, inclined roof greening, football field and golf course

Municipal Engineering: airport, road subgrade, subway, tunnel and landfill

Construction works: upper or lower layer of building foundation, indoor and outdoor wall and bottom plate of basement, roof, roof anti-seepage and thermal insulation layer, etc

Hydraulic engineering: anti seepage of reservoirs, reservoirs and artificial lakes

Traffic engineering: highway, railway subgrade, embankment and slope protection layer
Laying procedure
Clean up the garbage and cement on the paving site to make the site free of obvious concave convex
The top of outdoor garage and roof garden need 2-5‰ The slope of the

When used, the water discharged from the drainage board can be centrally discharged to the nearby sewer or the nearby urban sewer

To prevent water seepage on the basement ground, the ground is raised on the foundation, that is, a layer of drainage board is made before the ground is made, the circular protrusion is downward, and a blind ditch is left around, so that the groundwater can not come up
The seepage naturally flows into the surrounding blind ditch through the space of the drainage board, and then flows into the sump through the blind ditch

The basement wall is impervious, and the drainage board can be laid on the main wall of the building, and the round protruding table surface faces the main wall
A layer of single wall or steel wire mesh powder water protection drainage board is built outside the drainage board to make the water seepage board outside the wall directly flow into the blind ditch and directly into the sump

When laying the drainage board anywhere, care must be taken not to let the garbage such as soil, cement and yellow sand enter the front space of the drainage board, so as to ensure the smooth space of the drainage board

When laying the drainage board, protective measures shall be taken as far as possible
When laying the drainage board in the horizontal or outdoor garage, the filling operation shall be carried out as soon as possible to prevent the strong wind from affecting the laying quality of the drainage board
The waterproof layer of basement and inner wall shall be made as soon as possible to prevent the drainage board from being damaged by people and objects

The backfill is cohesive soil
It is ideal to lay 3 ~ 5cm yellow sand on the geotextile
The backfill conducive to the filtration of geotextile water is nutrient soil and light soil
There is no need to lay yellow sand
This soil itself is easy to filter

During the laying of the drainage board, the next 1-2 fulcrum can be overlapped with the right side, or aligned with the two bottom plates
The top is overlapped with geotextile
As long as the drainage channel of the drainage board is not carried out, the drainage can be kept smooth
