Composite drainage board is made of polyethylene or polyvinyl chloride, and usually connected with a layer of geotextile to prevent the passage of soil particles in applications, which thereby avoids the blockage of the drainage channel and makes the smooth drainage of the channel.
The traditional drainage method uses brick and stone tiles as the filter layer, and uses excessive cobblestones or gravel as the drainage layer to discharge the water to the designated place. Now the application of composite drainage boards to drain water saves time, energy and investment, and also reduces building loads.
Description:
The plastic drainage board, or dimple membrane, is made of polystyrene or polyethylene (HDPE) as the raw material, the plastic plate of which is punched into hollow conical or cylindrical column. The raw materials have been greatly upgraded and changed. Now the drainage board is made of polyvinyl chloride (PVC) as raw material. The compression strength and overall flatness are greatly improved.
Functions:
Prevention and protection
The drainage board can effectively protect the structures and the waterproof layer, and resist various types of acid and alkali corrosion and plant root in the soil, and also protects buildings and waterproof layers from being damaged during the backfilling process for the underground wall.
Sound insulation and ventilation:
Laboratory data show that polyethylene (HDPE) or polyvinyl chloride (PVC) drainage board can effectively reduce indoor noise by 14 decibels at 500HZ, drainage board have obvious noise reduction and sound insulation.
Specification:
The width is from 1~3 meters and the length is from 4~10 meters or customized.
Applications:
The drainage board is better than traditional stone and ceramic materials from the aspect of drainage and economic benefits, and widely used in the projects of retaining wall, basement, tunnels, slope protection and highway roadbed.
