Drainage board is made of polystyrene (HIPS) or polyethylene (HDPE) plastic base plate stamped into a conical platform or stiffener ribs (or hollow cylindrical porous), a width of 3 meters, length 10 meters or 15 meters.
Drainage board sub-coiled material and sheet two series of which the coil is divided into 'hot melt' and 'lap joint' and 'self-adhesive' three types, using a special process to press the plastic sheet out of the closed convex cylindrical shell Body, forming a concave-convex film, shell continuous, with three-dimensional space and a certain support height, thermal adhesive butyl rubber strips at the time of edge processing production, geotextile filter layer covering the top of the shell, used for seepage, hydrophobic, drainage and water storage products . Also known as: self-adhesive PE drainage board, row sparse board, drainage protection board, water filter board, plastic bump drainage board, plastic sandwich board.
Main classification
Drainage boards commonly used in construction include: self-adhesive PE drainage boards, plastic drainage boards, storage and drainage boards, and coil drainage boards.
Seepage drainage board, composite drainage board, three-dimensional drainage board, sheet drainage board, etc.
1. Store the drain board in a dry, ventilated environment to prevent exposure and keep away from fire.
2. Please stand up or lay the drain protection board upright, and do not tilt or cross lateral pressure. The stacking height should not exceed 3 layers and stacking of heavy objects is not allowed.
3. When laying, it must be smooth and natural, laid along the slope or in the direction of water flow.
4. The single-spread geotextile shall be lapped with 150cm. The lap joint shall be sealed with glue or sand to avoid movement, and then backfilled. The first layer of backfill soil shall be ensured after compaction, and the layered backfill must be compacted.
