Engineered from a proprietary blend of synthetic and natural rubber, the SFFST Studded Under Ballast Mat features a specially contoured bottom stud geometry. This design ensures excellent self-drainage, preventing water accumulation that could cause track bed failure. Built to handle heavy axle loads up to 250 kN across all speed ranges, it provides exceptional structure-borne noise isolation while delivering superior mechanical strength and structural adaptability.
