Chengdu waterproof and drainage board manufacture

 、 Clean up the garbage on the paving site and level it with cement
There is no obvious concave convex on the site
The roof of outdoor garage and roof garden need 2-5‰ Slope making; 2
Roof greening and outdoor garage roof greening can be equipped with porous seepage pipes, so that the water discharged from the drainage board can be centrally discharged to the nearby sewer or the nearby urban sewer
3
The basement ground is impervious to water, and the floor is overhead on the foundation, that is, a layer of drainage plate is made before the floor is made, the circular protrusion is downward, and there are blind ditches around, so that the groundwater can not come up
The seepage naturally flows into the surrounding blind ditches through the space of the drainage plate, and then into the sump through the blind ditch
4
The basement wall is impermeable, and the drainage board can be laid on the main wall of the building, and the round protruding platform faces the main wall
A layer of single wall shall be built outside the drainage board or steel mesh powder cement shall be used to protect the drainage board, so that the space of the water seepage board outside the wall flows directly into the blind ditch and directly into the sump
5
When laying the drainage board in any section, attention must be paid to: do not let the garbage such as soil, cement and yellow sand enter the front space of the drainage board to ensure that the space of the drainage board is unblocked
6
When the drainage board is laid, protective measures shall be taken as far as possible
When the drainage board is laid on the layer or outdoor garage, the backfill work shall be done as soon as possible to prevent the drainage board from being disordered by strong wind and affecting the laying quality
The waterproof of basement and interior wall shall be protected as soon as possible to prevent the drainage board from being damaged by people or objects
7
The backfill is cohesive soil
It is ideal to lay 3-5cm yellow sand on the geotextile, which is conducive to the water filtration of the geotextile; If the backfill is a kind of nutrient soil or light soil, there is no need to lay another layer of yellow sand
This soil itself is very loose and easy to filter water
8
During the laying of the drainage board, the lower 1-2 fulcrum can be overlapped with the right side of the side, and the two bottom plates can also be overlapped with geotextile
As long as there is no soil entering the drainage channel of the drainage board, the drainage can be kept smooth
