    AI Overview
    Roof garden geosynthetic drainage boards are specialized, high-density polyethylene (HDPE) sheets designed for green roof systems to manage water runoff and provide plant root protection. Featuring dimpled or "waffle" designs, these boards combine drainage with a water storage reservoir, enhancing plant survival and ensuring structural protection by preventing waterlogging and protecting waterproofing membranes. 
    Key Components and Functions 
    • Dimpled HDPE Core: Creates a flow layer for rapid drainage (up to 120 years of durability).
    • Geotextile Fabric Filter: A non-woven, filter layer (often 150g/m² or higher) on top prevents soil particles from clogging the drainage core.
    • Water Management: The dimpled design can either discharge excess water or store it for plant use during dry periods.
    • Protection: Protects the underlying roof membrane from damage during and after installation. 
    Key Benefits 
    • Waterproofing Protection: Protects roof structures from leaks.
    • Lightweight & Easy Installation: Simplifies installation, reducing structural load compared to traditional drainage methods.
    • Efficiency: Excellent drainage rates with continuous flow, even under high pressure. 
    Installation Considerations 
    • Orientation: Usually installed with the dimples facing down to allow water storage, with the geotextile facing up.
    • Overlaps: Drainage boards often feature a 3-inch or larger overlap to ensure continuous coverage.
    • Slope: On sloped surfaces, overlaps should be managed as a shingled effect. 
    Commonly Used Products 
    • Sika® Drainage Mat: Used for water retention and drainage.
    • ABG Deckdrain: A high-strength polyethylene core with a filter fabric.
    • Eastgate Green Roof Drainage Board: Eastgate Supply features high-flow capacity.
    • Tremco TREMDrain GS: Engineered for green roof assemblies.
