double perforated drainage board
Our drainage sheets are manufactured from premium HDPE, PP, or customized polymer materials and are available in multiple heights, thicknesses, widths, roll lengths, and surface configurations to satisfy different engineering requirements.
Each drainage board can be laminated with high-performance nonwoven geotextile, creating an integrated filtration system that prevents soil particles from clogging the drainage channels while maintaining outstanding long-term water permeability.
Whether your project involves rooftop gardens, retaining walls, sports fields, basement waterproofing, tunnels, landfills, or air-pruning containers, TINM can recommend the most suitable drainage solution based on your specific engineering conditions.
Thanks to our advanced extrusion production lines, every drainage board features precisely formed studs with smooth edges and virtually burr-free punching, ensuring consistent drainage performance, easier installation, and superior product quality.
Engineered Drainage Solutions That Replace Traditional Gravel Drainage
TINM Synthetics offers a comprehensive range of advanced drainage board systems designed to efficiently collect, convey, and discharge excess water in a wide variety of civil engineering, landscaping, and construction applications.
Unlike conventional gravel drainage layers, our double perforated drainage board provide excellent water flow capacity while significantly reducing installation time, transportation costs, and structural load. Their lightweight design makes handling and installation faster and easier, even on complex projects.
