Laying procedure: 1. Clean the laying site of garbage, cement screed, so that there is no obvious bump at the scene, an outdoor garage roof and roof garden need to find the slope of 2-5 ‰. 2. Green roofs and outdoor garage roof greening can be equipped with a porous pipe use, so can drain the water discharged into a local focus under or near the city sewer pipes. 3. basement floor seepage water drainage board material, based on the top floor of overhead, which is done in front of the floor drain is to do one round projections downward drainage board, left around the blind ditch, the groundwater is not come naturally flow into the surrounding water seepage through the blind ditch drainage board space, and through blind ditch into the sump. Bump-type drain board has a unique convex structure can provide efficient drainage space, but also due to the construction of its convex shape, position in the tunnel portal blocking treatment of the anti-drain if you do not tip, responsibilities seepage probably from the gap at the Portal after anti-drain outflow drainage affect the overall effect, so the construction of the drainage board bump us to be cautious. Bump-type drain board materials are difficult to break plastic drainage board type, placed in sandwich construction drainage board manufacturers, the decomposition of more than 100 years; for underground works in the roof or a green roof, high compressive strength, load light. Compared with the conventional process, the drain and geotextile composite, with drainage, waterproof, breathable, moisture, every root and other functions in one. Bump-type drain application projects: Garden Project: garage roof greening, roof garden, soccer fields, golf courses, beach engineering, municipal engineering: road embankment, subway tunnels; Construction: building the basis of the upper or lower, basement and outside walls, roofing and insulation and other impervious Traffic Engineering: various engineering highway, railway embankment, dams and slope protection layer and other projects.
