Handling roof penetrations properly
Handling roof penetrations properly
We manufacture a wide range of options to retain green and garden roof systems. It is also important to plan to use around any roof penetrations.
We also manufacture high quality stainless steel roof drain inspection chambers to fit single and dual (with over flow) internal roof drains. Our roof drain inspection chambers have flanges with folded edges so that there are no sharp corners on roof membranes! (Learn more)
All components are designed to meet or exceed the flow rate of all manufactured HDPE, Polypropylene and Aggregate based drainage systems for vegetated and garden roof design.
Our metal green roof edge is slotted all the way to the bottom to facilitate any level of moisture and promote drainage. Properly installed, our components will not restrict the flow of water through media and drainage in any storm event. The only water detained is the result of the retention that has been engineered and designed into the media and drainage components.
Design possibilities are limitless. We offer a consultative service for Architects and Design professionals. Please contact us using our quote template.
