Product Description HDPE Drainage Sheet production line is our newest product. On the base of our conventional sheet machine, we refreshed the rollers on the calendar, and got further development in this industry. The final HDPE sheet is a dimpled plastic sheet that can be used in various waterproofing applications. The dimpled nubs create a vapour and thermal insulation barrier for both internal walls and walls that are adjacent to waterproofing membranes, while also protecting the waterproofing membrane from the backfill in underground structures. The Drainage Sheets offer protection against any dampness in ground slabs and also create a cavity control layer, while The integrated non-woven geotextile covering the nubs prevents soil particles blocking the drainage sheet, creates an air gap for reliable ventilation and allows inflow and transport of water from surrounding soil.
