Time-lapse video of the 2012 installation of a LiveRoof Deep 6" System project in San Antonio, Texas. Valleycrest Companies installed the system, which was grown to full vegetation using native and adapted non-native plants by Joss Growers. Joss Growers selected plants to provide a full canopy of soil coverage and to hold up well under hot, dry, humid conditions typical of the region. The installation of over 13,000 SF took nine days to complete. The building is applying for LEED Platinum status.
LiveRoof, LLC (http://www.liveroof.com) is the horticultural science company that developed the LiveRoof® Hybrid System: the only green roof solution installed as a naturally functioning ecosystem with thriving, fully mature plants. Combining the best elements of proven green roof technologies, LiveRoof establishes a seamless vegetative surface rooted in a continuous layer of soil. This design maximizes environmental benefits, energy savings and rooftop aesthetics.
LiveRoof modules, when populated with a base mixture of flexible-stemmed hardy sedums (the backbone of the LiveRoof product line) were wind tested on 1/25/08 with wind speeds exceeding 110 MPH. In this test, the LiveRoof planting (4’ x 5’) was surrounded with Edging and first exposed to 10 minutes of wind at 95 MPH, followed by 1 hour and 50 minutes at 110+ MPH. The wind was impinged directly upon the surface of the LiveRoof planting as would be the case when testing other roof coverings. Remarkably, at the end of the test period, there was no loss of growing medium and all plants remained well rooted and intact. Throughout the test, the plants simply arched over, held in place by their root systems. This test demonstrated the value of full vegetative cover as a means of stabilizing the green roof system.
