Product Details

Hot sale hdpe green roof waterproofing drainage board is through professional mechanical structure design, it has a convex platform wall thickness, and accompanied by reinforcement structure, high compressive strength, good drainage prevent not degrade. After through hot melt welding, the resistance of plant puncture, acid and alkali resistance, aging resistance, and it is for building a waterproof formation of flexible protection, making whole waterproof layer enclosed space inside in the long run, not easy aging. Greatly extending the waterproof layer of using a fixed number of year.

Pondage and drainage board has the special structure, which can quickly and effectively derive rain and greatly reduce or even eliminate the waterproof layer of hydrostatic pressure, also can achieve active waterproof effect through this initiative guide water principle.

Pondage and drainage plate material itself is a kind of very good waterproof materials. By using reliable down the slope of the overlapped method, it is to become a kind of very good auxiliary waterproof material. Pondage and drainage plate can effectively reduce the indoor noise. Drainage shielding panels have very good ventilation moisture proof effect to use on the ground or metope.

Hdpe green roof waterproofing drainage board procedure

1. Clean up the garbage at the paving site, level the cement, and make the site have no obvious bumps. The outdoor garage roof and roof garden need 2-5 slopes.

3. The ground floor of the basement is protected against seepage, and the floor is raised above the foundation, that is, a layer of drainage board is formed before the floor is made. The rounded platform is downward and there is a blind ditch around it so that the groundwater does not come, and the water seepage naturally passes. The space of the drainage board flows into the surrounding blind ditch and then flows into the sump through the blind ditch.

4. The underground indoor wall is impervious to water, and a drainage board can be laid on the main wall of the building, and the rounded platform faces the main wall. A layer of a single wall or a wire mesh cement is used to protect the drainage board from the outside of the drainage board so that the space of the seepage board outside the wall flows straight down into the blind ditch and directly into the sump.

Waterproofing of the basement and interior walls should be done as soon as possible to prevent the drainage panels from being damaged by people or objects.

7. The backfill is cohesive soil. It is ideal to lay 3-5 cm of yellow sand on the geotextile, which is beneficial to the drainage of geotextiles. If the backfill is a nutrient or light soil, there is no need to lay a new one. A layer of yellow sand, the soil itself is very loose and easy to filter water.

8. When the low price hdpe green roof waterproofing drainage board is laid, take the next 1-2 fulcrums on the side and the right side. You can also touch the two bottom plates.
