Disclaimer: This section is an easy-to-follow instruction guide to install Hydropack®. Please read it carefully before you schedule and organize the installation and fax the certification back to Vegetal i.D. 585-343-6401. You can download the certification document here.
The contractor is responsible for the quality of every Hydropack installation. Care should be taken to avoid damaging the waterproofing membrane and the plants, both before and during the installation.
The Vegetal i.D. team can provide you with support for your green roof design, including CAD drawings, plant selection, installation, and maintenance. Don't hesitate to give us a call if you have any questions. Tel: 585-343-6400.
Is this your first Hydropack installation? Call us to ask a representative to come on site.
Information we Need
- Desired date and time of delivery
- Contact onsite: name, phone, email
- Type of truck (dry van, flat bed, etc.)
- Vegetal i.D. will contact you to set up the shipment. If you need to postpone the shipment, contact our logistics specialist at least 10 days before the shipment. If delayed for more than 2 months, there may be a surcharge for plant maintenance.
- Read and follow carefully the architect's specifications and the waterproofing membrane manufacturer's requirements. Find out which protection fabric, root barrier and vegetation free zone are required by membrane manufacturers to obtain the TSW (removal warranty).
- Before installing the modules, inspect the waterproofing surface to ensure that it is watertight. This will require a flood test (the controlled flooding of the entire roof with no less than 2 inches of standing water).
- The surface of the waterproofing membrane should be swept and washed.
- While the protective fabric is being put into place, no other activity should be carried out on the roof.
Shipments may be delayed, but no later than 10 days before the merchandise leaves the nursery.
If the trays can not be installed on the same day, please contact Vegetal i.D. for instructions.
The Hydropack trays are stacked on top of each other on a standard pallet.
Per truckload, we can transport about 3,200 sq. ft. per truckload 1,200-1,280 trays (288-308 m2)
One pallet is 2,200 lbs; 156-166 sq. ft., 60-64 trays (14.4- 15.4 m2)
We use flat bed trucks, dry vans, and temperature controlled reefer trucks
– simply let us know which is most convenient for you.
|Hydropack is packaged on pallets rather than racks. This allows trucks to leave as soon as they have been unloaded, and simplifies site management.|
- Gloves for each crew member
- 3 Knives or 3 pairs of scissors
- 1 Wheelbarrow (if gravels in the vegetation free zone)
- 1 Chalk Line
- 1 Circular saw or reciprocating saw
- 1 Shovel
- Roll out the Root Barrier and/or protection fabric overthe waterproofing membrane (consult the waterproofing manufacturer's recommendations)
- Overlap the sheets by a minimum of 2 inches.
- Take 2 empty Hydropack trays and place them at one corner of the roof. This will allow you to visualize the sequence you will follow when arranging the rest of the trays. The order should always be from left to right.
- Remember: for most specifications you will need to create a Vegetation-free Zone along the perimeter of the roof and around any rooftop equipment. Measure the width of the vegetation-free zone and draw a straight chalk line to mark the edges from which you will begin installing the trays. The lines have to form a perfect 90 degree angle.
- In some cases you may find it necessary to cut Hydropack. If so, empty the tray using the filter fabric to lift the soil. Cut the tray with a circular saw/knife or reciprocating saw. Position the tray with the remaining edges facing outward. Cut the soil and plants with a knife and replace them in the tray (see page 67).
- When all the trays are installed, fill the space around the perimeter with gravel ballast. Use the wheelbarrow to move the gravel around the roof, and use the shovel to spread it.
|Hydropack saves you money because it allows you to create vegetation-free zones without the need for aluminum edges. And because Hydropack's All-in-One system already includes drainage, water reservoirs, and filter cloth, so you save time on installation as well.|
- Hold the Hydropack tray with the female hooks facing you.
- Position the tray next to the trays already in place.
- Holding the tray by the top right hand and bottom left hand corners; lift them ½''.
- Slide the male hooks down into the female hooks.
- If the hooks don't slide in all the way use your foot to press them into place.
|Hydropack is the only tray with an interlocking system designed to allow water and nutrients to circulate. The strong interlocking system protects the trays from being uplifted by the wind.|
- 1 Circular saw or reciprocating saw
- In some cases you may find it necessary to cut Hydropack. If so, empty the tray using the filter fabric to lift the soil. Cut the plastic tray with a circular saw/ knife or reciprocating saw. Position the tray with the remaining edges facing outward. Cut the soil, filter and plants with a knife and place them back into the tray.
Hydropack can be cut easily to fit odd dimensions and angles.
We recommend emptying the tray before cutting the plastic following these steps.

- Irrigation supply:
- hose, tripod sprinklers
- Irrigation timer
- Position hoses and overhead sprinklers so that they provide optimum coverage of the vegetated area.Program the irrigation for 30 minutes.Check the Hydropack reservoirs in different places to make sure they are full of water, if they are not, water for a little longer. To check the water level in the reservoirs, lift the filter cloth in the tray.
- For the first year, the vegetation will need to adapt to its new environment. We recommend that you water during the summer (July-August), once a week for 30 minutes.After the first year, water only during periods of drought: > 90 °F (32 °C) with less than 0.6'' rainfall (15mm) for 20 consecutive days.
For the first month, the vegetation must be checked regularly, at least on a weekly basis to ensure that the plants are adapting well. After one month, the plants can be checked quarterly.
