Pre-Grown: Integrated Sub-Surface Irrigation

Advanced Green Roof Pre-Grown is delivered to the project site fully vegetated with your choice of preferred plant mixes. Once installed, the pre-vegetated modules provide an instant greening effect on your roof. Our pre-grown system is cultivated by professional horticulturalists in a controlled greenhouse setting to ensure healthy plants upon project delivery. AGR pre-grown includes our patent-pending drainage layer, capillary irrigation mat and bio-degradable sidewalls. The bio-degradable sidewalls begin to decompose after installation to create a 3” deep, monolithic soil profile to optimize water, nutrient cycling within the soil and root movement. Therefore, AGR pre-grown is installed in a modular fashion, but overtime functions like a traditional built-up system by creating a more complex landscape ecosystem. The modular drainage layer can easily be lifted up from the roof membrane so that portions of the roof deck are easily accessible for maintenance purposes. AGR pre-grown is currently available with our standard 4” media depth and also 2” media depth for ultra-lightweight applications.

[tab_first] Over three years of green roof research and development went into Advanced Green Roof pre-grown. Data from green roof research studies pointed to the need for integrated subsurface irrigation as well as bio-degradble sidewalls for maximized green roof performance. An integrated subsurface irrigation system increases water efficiency if supplemental irrigation is wanted and also improves green roof performance. Plants in a container over time will become root bound. With AGR Pre-Grown, bio-degradable sidewalls degrade over time allowing plant roots to move freely through soil layers accessing nutrients and soil moisture. AGR was researched and designed to promote long lasting green roof beauty.

[tab] Installing Advanced Green Roof Pre-Grown is a quick and easy process. Trays come to the site pre-grown with established roots. Trays are set down and interlock into adjacent trays. Drip lines are then installed feeding through irrigation channels. A “guiding bullet” attaches to drip lines to help feed the lines through the irrigation channels as seen in slide 6 above. If irrigation is spec-ed in on a project the drip lines connect to a lateral line which connects to a value(s) controlled by a specified controller. If irrigation is not spec-ed in the drip lines are capped off. If irrigation is wanted or needed there after the install irrigation hookup is an easy and simple process as the irrigation infrastructure is already installed.

[tab] Advanced Green Roof Pre-Grown tray is warranted against photodegredation and material defects for 20 years from the date of installation if AGR has edging, pavers or parapet surrounding.
AGR currently offers a 20 year Total System Warranty with Versico Roofing Systems, Inc. Other membrane manufacturer warranties may be considered on a project by project basis.

[tab] We work with clients to specify green roof plants. Because AGR integrates subsurface irrigation, plants other than Sedum can be specified leading to more plant design options. Please contact us for more information on our green roof plant mixes and plant specification guidance.
