The Sand Cap Build-Up System

The Sand Cap Build-up System is an excellent Sportsturf renovation technique that involves installing a primary drainage system followed by multiple topdressings with ½” of USGA sand. Generally, two topdressings a year should be planned for and they should be added each subsequent year until the sand cap has reached a 4” depth.  www.turf.msu.edu/built-upsandcapped-athletic-field-system
