Coordinate the roof design
Review structure, load, falls, drainage and the planned vegetation.
Green Roof Waterproofing Systems
Explore the waterproofing foundation of a vegetated roof, including drainage, root protection and access for future maintenance.
Vegetated roof assembly concept.
UNDERSTAND THE SYSTEM
What goes into it.
Below the planting, a green roof needs a coordinated waterproofing and drainage design. Consider the roof structure, outlets, root protection and future access before choosing the membrane.
- 01
Waterproofing membrane
The membrane must be selected for the complete roof assembly and the relevant root-resistance requirements.
- 02
Protection & root-control layers
The design determines whether separate protection and root-control components are needed.
- 03
Drainage & filtration layers
Drainage, filtration and growing media are coordinated with outlets and the structural design.

FROM SURFACE TO FINISH
How the work is approached.
A planning overview. The specified system and current technical data define the installation.
Install and inspect waterproofing
Complete the membrane and details; inspect before covering them with the landscape build-up.
Add the living layers
Install the specified protection, drainage and planting layers while keeping maintenance access clear.
PLAN YOUR PROJECT
Let’s start with your surface.
Provide the roof build-up and landscaping design. Confirm the membrane, root-protection and drainage layers as one compatible assembly.
- Roof structure, slope and drainage layout
- Root-resistance evidence for the specified system
- Protection layers and maintenance access
