Why Synthetic Grass Needs Infill

August 09, 2022

If you have been considering artificial grass in Pittsburgh, you’re certain to hear about one very key element of turf — infill. Infill is what causes the turf stand up and replicate the feel of the real thing. Here are a number of facts you must know about synthetic grass infill.


What Precisely is Infill?

Infill for synthetic turf is important for the appearance and feel of the grass. Infill is the material that's situated between the blades of artificial grass. It assists the blades in standing up and bouncing back to their original position after any pressure they might be exposed to (think footsteps, children or pets playing on the turf, etc.). It also plays a crucial role in offering outflow, keeping out odors, and, most importantly - protecting the grass base.


What Forms of Infill Are Employed?

A wide variety of infill substances can be used for artificial turf. Every one of them gives the same benefits but might not provide those advantages the same manner. Let’s check out the different forms of infill that are popular for current generation of turf.


Crumb Rubber

Crumb rubber is made from old truck and car tires. They are ground up and recycled, with all of the metal and fiber elements of the tire being removed during the process. Then, the newly made rubber pellets are classed by size. You will many times see crumb rubber infill on sports turf due to the fact this type of infill is durable and offers amazing shock absorption and the best traction for athletes.


Silica Sand

Silica sand is made from quartz that is weathered by the power of water and wind, reducing it into tiny sand grains. This is the most common kind of infill for grass in Pittsburgh today because its shape helps synthetic turf blades stand up and bounce back easier when force is applied. It also helps keep some moisture, providing you a cooler surface.


Acrylic-Coated Sand

Acrylic-Coated sand often employs technology such as Microban® for its antimicrobial characteristics to stop bacteria and harmful microbes. Acrylic-coated sand doesn’t crush over time like some infill types do, so it leaves more space for water or urine to flow through the turf as easily as ever.



Organic materials are getting popularity today, by the virtue of their eco-friendly compounds. Organic infill is generally produced from things like walnut shells, coconut shells, or cork. At Last Lawn, we use Shawgrass' organic infill which uses coconut imported from Sri Lanka or India, as they are the top supplier of coconut fibers globally. Geofill is the finest quality natural infill available — substituting soil for landscaping projects. Because of the saltwater retting treatment, Geofill is resistent against mold, mildew, and salts.
