抄録

In order to avoid vegetation-dependant damages of waterproofing membranes for roof greening, a test procedure for evaluating root resistance of it was developed. Test procedure is as follows. Two kinds of trees and two kinds of grasses are planted in inner containers of punched stainless metal sheet, inside of which waterproofing membranes are applied, and then, the inner containers are placed in outer containers. After being raised for two years in a greenhouse, the inner containers are removed from outer containers. The test membranes are inspected whether roots penetrate or don't through them.
