Application
The root systems of plants on intensive green roofs can damage the building structure. Ad- ditionally, various wind-carried plants may ap- pear on extensive green roofs, including those with aggressive roots or rhizomes, which can threaten traditional waterproofing. Therefore, appropriate root protection must be ensured for every vegetated roof surface.
