David was asked to teach the NRMCA Pervious Concrete Technician class by the NRMCA local sponsoring group ACI Northern California chapter. The location was in Truckee, CA and after the class and test, the class went out the TNT Materials Yard for a demonstration pour. We had good pervious pouring weather and great participation!
