T-shaped PE lamination drainage sheet is formed by extruding and squeezing with polymer. T-shaped cylindrical top surface is laminated with non-woven fabric to prevent the soil particles from getting through, and avoid blocking the drainage channel and make drainage smoothly. Meanwhile, it can also be used to resist long-term high pressure without deformation, and maintain the original water discharge. The long-term pressure-resistance property of T-shaped PE lamination drainage sheet makes it can withstand not only the weight of concrete-floor and the load, but also the unavoidable external pressure and impact strength from the vehicle, workers trampling and concrete perfusion during constructing. The filtering layer geotextile laminated on the bottom surface is used to avoid the drainage channel blocking by impurities, such as the particles of backfilling and concrete.

Applications

T-shaped PE lamination drainage sheet is more superior and reliable than the traditional building stones, ceramsite drainage and other filtering layers in terms of drainage function and economic benefits. The product is mainly used for drainage of waste yard, roadbed and surface of highway, railway, tunnel, underground structure, retaining wall, garden, playground and so on.
