How it works
Tournesol GRT3 Greenroof Trays
Tournesol Siteworks offers a simple, durable tray that can be used with any type of greenroof-type engineered soil in nearly any modular greenroof application. Modular trays are ideal for retro-fit applications, and small- to medium- size installations. Trays allow plants and soil to be shifted or moved from time to time, especially for roof maintenance or repair.
Tournesol Siteworks uses high density polyethylene to create a flangeless tray that will last the life of the project. The units feature a ½” storm water retention layer, and corner drain holes leading to 1” drain channels below. Use the 4” deep tray for extensive, the 8” for intensive greenroof applications.
