Aerification is a vital practice that is performed to ensure that the soil profile beneath the turf is properly maintained. Aerification is the act of removing organic material to relieve compaction, increase water infiltration rates and increase oxygen in the soil. Common core aerification relieves the profile down to a maximum of approximately 6" below the surface. Because of our need for deeper alleviation, we chose to utilize the drill and fill technique. The drill and fill machines drill down through the profile up to 10 inches and removes organic material when exiting. The machines then fill the drilled hole with sand.
