San Diego State Shifts to Infill-Free Turf to Cut Maintenance

Traditional synthetic fields rely on infill to maintain structure, but constant heavy use leads to displacement, forcing operators into a cycle of redistribution and replenishment. The new installation at the university’s recreation center sidesteps these maintenance hurdles by utilizing engineered fibers and backing to simulate performance characteristics without loose materials. This design choice directly addresses common operational friction points in high-traffic intramural facilities.

Beyond operational efficiency, the project reflects a growing institutional focus on the full lifecycle of campus investments. Reginald Cabanilla, director of facilities and sustainability at the university, noted that the decision was driven by the system’s lack of PFAS and primary microplastics, alongside its potential for end-of-life recycling. As universities face mounting pressure to lower the environmental footprint of their athletic grounds, this transition highlights a shift toward materials that prioritize circularity and long-term durability over conventional construction methods.
