During consideration of the sports complex project the city heard various concerns from residents about the use of crumb rubber as infill for the synthetic turf. The Sports Complex at Bernal Community Park will be using an alternate infill known as ZeoFill®. ZeoFill is a brand name of a product made from zeolites which are naturally occurring minerals found in specific types of sedimentary rock (many in California, Nevada and Utah). While the use of ZeoFill is relatively new, its excellent absorption qualities, organic nature and overall safety assessment, make it an attractive alternative for synthetic turf applications. The City of Pleasanton selected this option during the planning and bid process. While the primary difference between the two field options is the elimination of crumb rubber and the inclusion of ZeoFill, the inclusion of a shock pad under the turf will replace some of the cushioning lost from eliminating the crumb rubber. Manufacturers maintain the shock pad will also extend the life of the artificial turf and improve playability overall. Learn more about ZeoFill here.
