GreenTech ITM™

Built-in drainage channels allow water to flow through the soil into the open channels and directly to roof drain outlets. At the same time, each high-density polyethylene module protects the roof surface from root infiltration and damage to the roof membrane. The result is a robust planting surface, with sufficient root depth, that is more lightweight and flexible than other green roof options.

"I can assure you that I was very impressed with the GreenTech® modular system and I can see many opportunities to use that system to create roof-top gardens on flat roofs. One of the big problems with most roof top gardens is that there is insufficient slope to drain water through gravel resulting in numerous drainage problems. The GreenTech® system does not restrict the movement of water and it allows for sufficient root depth".
