Infill Vs. No Infill
In nature, grass blades are resilient because of the root-to-blade nutrient process. Synthetically, we can mimic the effect with artificial grass using tufted polypropylene thatch backing that supports a softer polyethylene blade. This backing gives artificial turf the ability to bounce back.
Now, all artificial turf needs some sort of infill. The type and quantity of infill depends on installation location and the thickness of your chosen turf blend. Infill for synthetic grass comes in four traditional forms: silica sand, rubber, a sand-rubber mix, and Durafill sand. Refer to the chart to explore the differences in types of infill.
Artificial grass infill helps give synthetic turf the feeling of real grass — it emulates the impact absorption qualities of soil. Infill also helps weigh down imitation turf to keep it from getting wrinkles or ripples caused by movement.
|Rating||Composition||Applications||Amount per Sq Ft||Pros||Cons|
|Good||Silica Sand||Ideal for low-traffic areas (hills, balconies, decks, thick turf, commercial or non-use fields)||1-2 pounds||Inexpensive
Easy to find
Easy to install
|Sand is angular (not round) and can become hard
Can hold pet odors
|Better||Rubber / Sand Rubber Mix||Best for light to medium traffic areas (lawns, playgrounds, commercial or retail areas, some athletic fields)||½ pound (one 50 pound bag covers 100-200 square feet)||Very soft
Adds volume to turf
Keeps fiber upright and in place
Easy to install
|Can get hot
Can transfer black rubber dust onto clothes and shoes
Can hold some odors
Does not kill any bacteria.
|Best||Durafill Sand||For all types of artificial grass applications (lawns, high-traffic locations, athletic fields, playgrounds, dog runs)||1-2 pounds||Kills bacteria
Does not absorb liquids (great for pet areas)
Softer impact absorbency
Safest for kid/pets
|More expensive Does not cover same volume as rubber mix
Extra padding required for playgrounds and athletic fields
