Aerodynamic Evaluation

Aerodynamic Evaluation

Since exposed geomembranes and geosynthetics are susceptible to uplift and damage from strong winds and hurricanes, the ClosureTurf® technology was developed to withstand these forces. ClosureTurf® was evaluated 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 ClosureTurf® 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).

ClosureTurf® provides 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.
