An Advanced Eco-Roof Technology for Low Impact
Development in an Urban Environment
Columbia Green's patented Advanced Vegetative Roof System® (AVRS®) incorporates Eco-Technology that enhances storm-water detention, filtration, retention and evapo-transpiration at the source.
Through the use of engineered detention troughs, drainage orifices, bio-filtration growing media, phyto-remediation plants, and storm-water retention Columbia Green's AVRS®system can improve stream quality in watersheds while reducing urban inflows to a city’s storm-water system.
Columbia Green's AVRS® system lowers the overall Eco-Roof cost of design, installation and maintenance for new development, urban retrofits and revitalization projects.
AVRS® Trays is the only modular Eco-Roof system that is a fully interconnected and integrated roof system that encapsulates the roof. It is also available in pre-grown, post-planted, tiles and hydro-planted succulent, local and native plants.
AVRS® Multilayer is the only multilayer Eco-Roof system that provides positive airflow up through the system while allowing measured detention and retention down through the system. It is available in post-planted, tiles and hydro-planted succulent, local and native plants.
Both the AVRS® Trays and AVRS® Multilayer system can be combined to form a hybrid eco-system for maximum stormwarter management incorporating creative design for shaped and angular areas.
