Hydropack: The only green roof tray with a 0.4 inch water reservoir

Each module contains all necessary components for a successful green roof system: A drainage layer, filter, a substrate layer that is specifically adapted to rooftop contidions, a vegetation layer, and of course, a dedicated water reserve.

  1. The substrate is protected from standing water. 
  2. The substrate layer is about 3 inches thick and is protected from standing water through a drainage layer.  The filter layer at the bottom of the substrate prevents the soil media from leaching outside the tray while enabling high water retention in a low weight system.  The Hydropack tray is designed by Vegetal i.D. to withstand rooftop conditions.  It provides an optimum combination of permeability, water retention, and durability.
  3. Excess water is discharged efficiently. 
  4. Each Hydropack green roof tray has 47 drainage holes per square foot to enable efficient evacuation of excess water.
  5. Efficient use of rainwater 
  6. The Hydropack tray has a permanent reservoir located at the bottom of the tray to regulate rainwater on the roof.  Excess rainwater is collected within a 1.2 inch water reserve that stores 0.22 gallons of water per square foot, and can be absorbed over time by the vegetation through a wicking process known as capillary irrigation.
  7. Water and nutrient resources are shared between trays. 
  8. Water is evenly distributed over the entire roof with an efficient and patented interconnecting system that enables water and nutrients to be shared between green roof trays.

 

Hydropack is suitable for both flat and steep roof systems

Due to its natural framing and all-in-one system Hydropack lends itself well to steep slopes with up to a 200% pitch.  Thanks to the Acropack attachment system, each tray can be affixed securely to the roof without piercing the roofing membrane. Our solutions and techniques were developed by our research and development team with the benefit of over 20 years of experience designing and building green roof systems.

 

 

Shipped with 95% coverage for an established green roof the day of installation

Hydropack is produced and assembled by Vegetal i.D. in our nursery in upstate New York.  Unlike other manufactures that outsource the growing of their vegetation to other nurseries, Vegetal i.D. maintains control of the quality of each and every tray sold, which enables immediate plant coverage of at least 95% on the day of installation.  With Vegetal i.D. you can leave the plants to us and be sure that your green roof project is a success every time.
