How Safe Is Artificial Grass Infill? 


Synthetic grass offers a lot of options for homeowners, especially those in areas where water is a premium. California homeowners find relief with the product because it is used to create a beautiful landscape while dramatically reducing water use and freeing up time because of its low maintenance. However, there are things surrounding the installation of synthetic grass that leave people with questions. One of those things is artificial grass infill. 

 Artificial grass infill is the product put in between the blades to help keep the blades standing straight. It also has other functions, such as helping with drainage and odor. Infill is an important component of artificial grass installation, but some wonder if some types are safer or more environmentally friendly than others.

 Let’s take a look at the different types of infills to answer that question. 

 Crumb Rubber

This has some mixed reviews. On the upside, it is made from recycled tires so those looking to keep it environmentally friendly like that. However, the same people are concerned that crumb rubber isn’t biodegradable. 

 Another plus of crumb rubber is its affordability. It is one of the least expensive artificial grass infills on the market. It is also highly comfortable because it offers more cushion than other infills. The downside of that is it can retain heat, so walking or playing on it in bare feet could hurt in the hot sun. That means it could pose a problem for pets also. 

 Pea or Chip Gravel

This is a natural product, so that is a plus for those looking to keep artificial grass infill natural. It is stone, so being biodegradable isn’t an issue. Pea or chip gravel doesn’t contain any hazardous byproducts and will last for the turf’s lifetime. It is heavy, so wind and water probably won’t move it.

 The disadvantages of pea or chip gravel are that they can become scattered over time through the normal run and play and may in up in areas where you don’t want them. Also, pea and chip gravel isn’t as comfortable as other types of infill.


 Sand is popular as an artificial grass infill because of a number of reasons. It is natural, comfortable, safe and affordable. One problem with sand infill is it can pack down when it becomes wet. It can hold odor of pet urine if the area isn’t rinsed regularly. It will need to be replaced over time because it becomes compressed. 

 Silica sand is an option that many people find helpful. Using it as an artificial grass infill remains affordable, although it’s a step up from regular sand. It has a microbial coating that stops the spread of bacteria, which makes it one of the safest choices, and it can absorb odors. 


 Some homeowners use a combination of artificial grass infills to make the most of each’s unique advantages. For instance, crumb rubber works well for playground areas while pea and chip gravel is an awesome choice for outdoor patio or courtyard areas. Sand mixed with silica sand works effectively for the overall yard and specialty areas like putting greens and dog runs.

 However, you choose, picking a good synthetic grass infill is an important decision in your installation so weigh your choices wisely.
