Green roofs have never been this simple to install.
Our substrate blocks combine a drainage layer, five sides of water retention layers, and growing medium dried into a block. Water has been removed, making the blocks extremely lightweight. Once installed, water from irrigation and/or rainfall saturates the blocks, creating lush, soft soil for growing.
More water retention layers for increased rainwater collection.
Lightweight for easy installation.
Stackable for easy shipping and storage.
Interlocking blocks increase stability of the green roof system.
