Green Roof System

The BUMATECH Light Weight Green Roof System (LGR) consists of Buma J-Drain drainage layer and Root Barrier. Buma J-Drain not only provides an no-clogging geotextile for filtration and free flow water channels to drain excess water away, but also retain water for plants to grow. The Root Barrier is used to protect against roots from penetrating into the waterproofing layer. In order to control the water content in the system, a water-retention mat can be added between Buma J-Drain and Root Barrier.
