What is the laying regulation of roofing siphon drainage board that?

1. Clean up the garbage on the laying site and make cement leveling so that there is no obvious concave and convex on the site. The outdoor garage roof and roof garden need 2-5‰ looking slope.

2. The water discharged from the drainage board can be collected and discharged to the nearby downpipe or the nearby city sewer.

3. Impermeable water on the basement floor is raised above the foundation, that is, before making the floor, a layer of drainage board is now made. The round protrude platform is downward, with blind ditches around it, so that the groundwater cannot come up, and seepage naturally flows into the blind ditches around through the space of the drainage board, and then into the catchment through the blind ditches.

4. Anti-seepage of the basement wall, drainage board can be laid on the main wall of the building, and the round protrudent platform faces the main wall. A layer of single wall or steel mesh cement is built outside the drainage board to protect the drainage board, so that the space of seepage board outside the wall directly flows down into the blind ditch directly into the water collection pit.

5. When laying drainage board in any section, pay attention to: do not let dirt, cement, yellow sand and other garbage into the front space of drainage board, to ensure that the space of drainage board is smooth.

6. When laying the drainage board, take protective measures as far as possible. When laying the drainage board at the level or outdoor garage, backfill the soil as soon as possible to prevent the wind from affecting the quality of laying the drainage board. Basement and internal wall waterproof to do a good protective layer as soon as possible, to prevent the drainage board is damaged by people or things.

7. Backfill soil is viscous soil, and 3-5 cm yellow sand is ideal for geotextile filtration; There is no need to lay a layer of yellow sand if the backfill is a nutrient or light soil, which is naturally loose and easily leached.

8. When the drainage board is laid, the side and the side right lap the next 1-2 fulcrum, and the two bottom plates can also be touched together, and the geotextile lap is used. As long as there is no soil entering the drainage channel of the drainage board, the drainage can be kept smooth.
