Prior to creating a VYDRO® substrate green roof, the base of the garden should be watertight and strong enough to resist a plant’s root system.
The VYDRO® substrate is rolled out, with the eggshell down and the geotextile fabric up.
The substrate can easily be cut to size with scissors or a knife.
The sedum or grass mats are carefully unrolled and placed on top of the VYDRO® substrate, and all on the same day to prevent suffocation.
As to enable the roots to adhere to the VYDRO® substrik ate, the whole green roof is wetted.
