American Hydrotech has developed a wide variety of solutions that manage stormwater runoff. Among the solutions are the company’s Garden Roof Assemblies. Varying depths of LiteTop growing media are integrated with Gardendrain, which addresses water retention and drainage. For projects with higher water holding capacity needs, Hydrotech offers its Garden Roof Rock Mineral Wool Assembly. This hybrid assembly combines the high water-holding capacity of LiteTop media with the exceptional water-holding features of needled rock mineral wool. In addition, American Hydrotech’s Protected Membrane Roof (PMR) Blue Roof Assemblies enable large quantities of water to be temporarily stored on the roof of a structure.
