AI Overview
Plastic water trays for green roofs are modular, interlocking containers designed to support vegetation on rooftops while managing drainage and water retention. They are often made from durable, UV-protected, and recycled materials like polypropylene (PP) or polyethylene (HDPE), designed to hold growing medium (substrate) and plants—typically sedum—in an extensive, low-maintenance system.
Key Features and Benefits:
- Modular Design: Trays (often 19-3/4” or 1'x2' in size) connect to form a continuous green surface, making installation, maintenance, and inspection easy.
- Water Management: These trays act like a sponge, featuring drainage holes and built-in, raised reservoirs (water storage tanks) that hold water for plants during dry spells while allowing excess to drain off, preventing waterlogging.
- Protection: The raised bottom design allows air to circulate underneath and provides a layer of insulation, preventing the roof from overheating and shielding the underlying waterproofing membrane.
- Durability: Made of high-quality plastic that won't rot, crack, or suffer from corrosion.
- Pre-grown Option: Many, such as the M-Tray® or Berland system, come pre-grown with sedum mats, allowing for an instant green roof.
Common Specifications:
- Material: Recycled Polypropylene (PP) or HDPE.
- Dimensions: Often available in sizes such as 19-3/4” (50 cm) or 1' x 2' modules.
- Depth: Usually around 3 to 4 inches, which is suitable for extensive sedum roofs.
- Weight (Saturated): Approximately 25-30 lbs per square foot.
- Water Storage Capacity: Up to 1800 ml (or 1.8 liters) per unit.
