Dimple drainage board can quickly and effectively export the rainwater, greatly reduce or even eliminate the static water pressure of waterproofing layer, through this principle of active water conduction can achieve the effect of active waterproofing. Waterproof performance: Polyethylene (HDPE) dimple drainage board material itself is a very good waterproof material. The waterproof and drainage board becomes a good auxiliary waterproof material by adopting reliable connection mode.

1. Landscape engineering: garage top greening, roof garden, football field, golf course, beach project. 2. Municipal engineering: road base, subway, tunnel, landfill. 3. Construction engineering: upper or bottom layer of building foundation, basement wall, bedding filtration and heat insulation. 4. Traffic engineering: highway, railway basement, dam and slope.1. Clean up the garbage and cement leveling of the laying site, so that there is no obvious bump on the site, and 2-5‰ slope is needed for the outdoor garage roof and roof garden. 2. It can discharge the water collected from the drainage board to a nearby downpipe or a nearby city sewer. 3 basement ground anti-seepage water, in the foundation above the floor, that is, before doing the floor to do a layer of dimple drainage board, the dimples contact the foundation, leave blind ditch, so that the groundwater does not come, seepage naturally through the space of the dimple drainage board into the surrounding blind ditch, then through the blind ditch into the sump. 4. Anti-seepage water in the basement internal wall, dimple drainage board can be laid on the main wall of the building, and thedimples faces the main wall. The dimpled drainage board is protected by a layer of single wall or a layer of steel wire mesh cement, so that the space of the seepage board outside the wall flows straight down into the blind ditch and directly leads to the sump. 5. When laying drainage board in any location, attention must be paid to: do not let soil, cement, yellow sand and other garbage into the front space of drainage board to ensure the space of drainage board is smooth. 6. When the dimple drainage board is laid, protective measures should be taken as far as possible, and backfill should be done as soon as possible when the drainage board is laid at the level or in the outdoor garage, so as to prevent the high wind from blowing disorderly drainage board and affecting the laying quality. Basement and inner wall waterproof as soon as possible to do a good job of protective layer, prevent the drainage board is damaged by people or objects. 7. The backfill soil is viscous soil, and it is ideal to spread 3-5 cm of 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 a layer of yellow sand, the soil itself is very loose and easy to filter water. 8. When the drainage board is laid, it can be overlapped with the right side of the drainage board at the following 1-2 fulcrum points. It can also be overlapped with two bottom plates together by geotextile.
