Stokes Green Roof: Days 2, 3, 4 and 5
The polyethylene root barrier comes in 18' wide rolls. It has to be cut and heat sealed together to provide a custom fit. This is the longest and most labor intensive step in the installation process.
Once the root barrier is installed the next step is to lay the protection fabric. This gives an extra level of protection to the underlying roof membrane.
Once the protection fabric goes down triangular conduit is placed on top. The conduit contains narrow slits which funnels excess water to the drains.
Once the conduit is installed the drainage mat is placed face down. The mat picks up excess water and moves it towards the conduit.
Stone edging is installed to prevent wind lift.
