Aerodynamic Evaluation

Since HydroTurf® is installed in areas susceptible to hurricanes, Watershed Geosynthetics performed aerodynamic testing to evaluate uplift from hurricane force winds. This evaluation was performed in the wind tunnel at the Georgia Tech Research Institute (GTRI). It was tested up to 120 mph without uplift. Based on these results, the HydroTurf System (with no internal anchoring) is projected to withstand 150+ mph winds when properly designed. The photo shows the test at 170 fps (120 mph).

HydroTurf has features that help mitigate the forces of wind. These include a porous surface to break the vacuum, and turf blades that will increase the aerodynamic boundary conditions and react against the wind causing a resistance to the uplift component.
