Infill Or Non-infill Artificial Grass, Which Is Better?

Do I need infill for my artificial grass, do you have non-infill artificial grass? Infill or non-infill, which is one is better? These are questions we are asked frequently. Generally speaking, no mater for landscape areas or football fields, , we always recommend using infill to add stability, resistance, and durability. but In some situations, you do not need to use infill, and we do have artificial grass that does not need any infills. These products were specially developed as professional non-infill artificial grass. This article will tell you why you need infill, and in which situation you do not need infill.

We will explain this according to different applications. 

  • Football Field
  • Tennis, Field Hockey, Putting Green and Multi-sport
  • Landscape & Play Areas

Football Field

First of all, we should understand why to use artificial grass infill (the most comman infils for football fields are quartz sand + crumb rubber, )

Why use artificial grass infill?

  • Infill provides a structure for the artificial grass fibers, helping the fibers to stand. The fibers of an artificial turf naturally lay “flat” without the infill material if the artificial grass has no thatch fibers in the root.
  • Infill provides a “cushion” effect when stepping over the turf. This protects the roots of the fibers and at the same time adding resilience to the whole artificial turf system. Normally infilled artificial grass system could take more traffic than non-infill artificial grass system under the same condition.

What is non-infill artificial grass?

Our non-infill artificial grass refers to those artificial grass with thatch fibers, narrow gauge (distance between rows) and high stitch rate. The thatch fibers are working similarly as infills to support the grass to stand, and to provide appropriate resilience.

In the below pictures, the left one is one of our non-infill artificial turfs, and the right one needs infill. 

Infill or without infill, How to decide?

Infill or non-infill, it depends on the conditions of your project. 

1. Landscape and play areas:

For outdoor high traffic areas, Whichever type of artificial grass you choose, we would advise you always to use sand fill. Ultimately, it increases the lifespan of the artificial grass. Using a common drop spreader or cast spreader to infill the sand. Once the material is spread over the artificial grass, it is then brushed into the fibers with a stiff bristle broom. You may need to hire a brush machine to infill the artificial grass for a larger project.

However, You might want to consider a non-infilled artificial grass for the following applications:

  1. Your yard contains severe slopes (gradual slopes are fine).
  2. You want a play area for the kids and pets.
  3. You want to put artificial grass around the swimming pool.

Without infills, kids can tumble down the rolling hills in the backyard, no fear that they will put the rubber granules or sands into the mouth. Its safer for pets without an increase in surface temperature. Heavy foot traffic is not a problem and you never have to worry about maintenance due to infill. It is also especially important when installing around pool decks or indoor applications. No infill will get caught in your pool filters. And no mess when using it indoors.

2. Football fields

Almost all traditional football grass needs silica sand and crumb rubber as infills. The fibers of a football grass naturally lay “flat” without the infill materials. Silica sand and rubber granule work together to provide a stable and flexible surface.

Sand and rubber infill stabilize and support the system

SILICA SAND

  • Stabilizes and supports the system.
  • Environmentally beneficial.
  • Accounts for 70% of total infill weight.

RUBBER GRANULE

  • Provide a softer artificial football grass surface and give bounce.
  • Rounded granules resist floating or displacement in high-use areas.
  • Environmentally beneficial.
  • Accounts for 30% of total infill weight.

Non-infill Football Grass

If you are planning to construct a 5-a-side, 4-a-side, 3-a-side, or indoor football field, we recommend our NON-INFILL football grass.

Our non-infill football turf combines the newest and most revolutionary yarn and tuft design to create a high quality, low maintenance, football pitch of the highest standard. Laid onto a shock pad (optional but recommended), it does not require sand or rubber infill which means faster installation, and less maintenance. Shorter blades make it ideal for multi-sport pitches, training pitches and smaller pitches such as 5-a-side.

Will the non-infill artificial grass provides enough resilience?

As mentioned above, one of the functions of infill is to provide a “cushion” effect. We have explained that the “thatch” grass plays a similar role in non-infill grass, but is it enough?

If 5-a-side, 3-a-side practice football field for practice, the non-infill football grass itself will perform well. If for landscape and pool surrounding, it is quite OK. But if you need extra resilience and better protection for a professional football pitch or playground, we recommend you add a layer of shock pad beneath the non-infill artificial grass.

Conclusion:

For landscape, We recommend using sand infill. If just for decoration, pool surrounding, rooftop, and no much traffic, it is ok to not use infill.

For play areas, we recommend infilling some silica sand to make the system more, stable, durable, and flexible. Meanwhile, we have very dense artificial grass products that can be used for a playground without infill. If you need to make sure the resilience, we recommend to add a layer of shock pad.

For a football project, we always recommend using infilled football grass for professional performance. But for a 5-a-side, 3-a-side or indoor project, our non-infill football grass is an ideal choice.

For other applications, we suggest you consult with an installer or contact us for more details.
