Huangshan build drainage board sales hotline: 1860538; 4341 151638; 18660, QQ: 17388; 17622 Products 1,860,538; 4341 hdpe drainage board is made of plastic plate after punching cone penetration units (or hollow cylindrical porous) made cone penetration Taiwan's top surface bonding layer of filter geotextile to prevent soil particles through, thus avoiding drainage obstruction, so that smooth drainage. The traditional use of brick tile drainage as a guide filter layer, the use of more pebbles or gravel as a filtration layer, the water discharged to the designated place. Now replace the pebbles treatment layer with a drain to drain is saving time, effort and energy saving investment, but also reduce the load of the building. Features: 151,638.186.60 good drainage system for normal use and life cycle of construction and civil engineering structures play an important role. HW type Drainage Board porous tubes with an effective drainage system sparse, long and short cylindrical drain and geotextile form a drainage system, to form a water seepage, water and drainage systems. Usage: 186.0538.4341 garden project: garage roof greening, roof garden, soccer fields, golf courses, beach projects Municipal engineering: road embankment, subway tunnels Construction: building the basis of the upper or lower, basement and outside walls, roof impervious and insulation and other transportation projects: roads, railway embankment, dams and slope protection layer laying procedure: 1. Clean the laying site 151,638.186.60 garbage, cement screed, so that there is no obvious bump at the scene, an outdoor garage roof and roof Gardens 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 water discharged discharged concentrated near water pipes under or near the city sewer 151,638.186.60 3. ground water seepage in the basement On the basis of the above overhead floor, which is done in front of the floor drain is to do one round projections downward, left around the blind ditch, up the mountain groundwater seepage flow into the surrounding natural blind through the drainage board space ditch, then into the sump through blind ditch. The interior basement seepage water, the body can be laid on the building wall drainage board, round projections for the main walls, drainage board outside and then a layer of single-wall masonry or cement powder steel mesh to protect the drainage board, so space outside wall seepage board straight down the inflow blind ditch directly caused sump. 5. In any lot laying drainage board, must be careful not to let dirt, cement, sand and other trash into the front space of the drainage board to ensure the smooth flow of the drainage board space. 151,638.186.60 6.

Drain in laying the right side and take the next 1-2 edge fulcrum, you can touch the bottom two together, the above use of geotextile overlap, as long as they do not enter the soil drainage board drainage channel can maintain drainage flow . Construction Notes 186.0538.4341 1, in the dry, ventilated storage environment drainage board, to prevent exposure, away from fire. 2, please stand up or lie flat drainage protection board, not tilted or cross horizontal pressure, stacking height not more than three layers, avoid heavy heap pressure. 3, laying should be smooth natural downslope or according to the laying of water. 151,638.186.60 4, when a single shop geotextile lap guarantee 150cm, lap by glue or sand compaction avoid moving, and then backfill, the first layer of compacted backfill guarantee before the next step, layered backfill must be compacted. 151,638.186.60 Contact: Wangjing phone: 1860538; 4341151638; 18660 please call QQ: 17388; 17622 Website: http: //www.jiasujiancai.com
