One of the questions that we often get at Artificial Turf Express is, “What kind of options do I have for infill?” For some, infill can make a significant difference in the lifespan of their turf, its visual appearance, the way it drains, and many other factors that need to be considered for DIY installers. Some infill types provide better cushioning for sport applications; others are more suited for dogs because they feature an anti-microbial coating that prevents odors and bacteria from pet urine. Certain turf installers are shying away from crumb rubber because of its negative press, while others swear by it for all athletic turf work. This can be very confusing for a novice turf installer or even a seasoned veteran. The purpose of this article is to help you understand the pros and cons of infill types, and answer the question, “What type of infill is best for me?”
