Protected Membrane Roofs (PMR) have traditionally required a ballast of stone or concrete pavers to stabilize and protect the underlying insulation and roof membrane from wind uplift and physical / environmental damage. HydroTurf® replaces these traditional forms of ballast with many advantageous. It is lighter and less costly with significantly better aesthetics. HydroTurf® has been shown to resist uplift at wind speeds over 120 mph. Also, since it is a hardened revetment with a 50+ year functional longevity, it provides excellent resistance to physical and environmental damage.
