All About Synthetic Grass Infill: What You Should Know

A primary reason why many of us opt to augment our gardens with a synthetic grass installation is to reduce the time spent on maintenance. However, some upkeep is still required. Infill also plays a crucial role in keeping artificial turf looking good and in excellent condition for as long as possible.

Here's what you should know about infill for synthetic grass.

What is synthetic grass infill?

Infill is a critical element in the preservation of a synthetic grass installation. It helps keep the individual grass blades upright for an authentic look and feel. Infill is also responsible for giving the turf a bouncy or cushiony feel when you walk on it. It protects the fabric mesh that creates the turf's foundation. Additionally, it offers the following turf benefits:

  • It keeps the grass weighed down to help prevent it from developing a carpet look. Once that happens, it will need stretching when it expands and contracts throughout seasonal changes.

  • It acts as a stabilizer. Following an extended period of foot traffic, infill prevents your grass from looking crushed and matted.

  • It also supports turf drainage, prevents or eliminates pet odors, and protects against UV radiation.

The type of infill required depends on how you will use your grass.

Types of infill

Several different types are available, with each kind intended to offer the best benefits. However, some types are better at delivering advantages than others. Here are some commonly used variations of infill:

Silica sand

Silica sand originates from quartz eroded by water and wind. The material is used in many commercial applications, including synthetic grass infill. Like other infill types, it helps keep the blades upright, but silica sand is typically the least expensive. However, the sand has an angular shape instead of rounded, leading to early fiber breakdown. It also retains moisture which can cause bacteria growth and lets mold and mildew develop on the turf's surface.

Crumb rubber

Crumb rubber grass infill is typical in sports applications. It consists of grounded recycled tires and provides the turf with a unique bounce. Therefore it's perfect for high-impact areas like a sports ground.

However, one downside to this kind of turf is it traps odors and heat to increase the warmth in the environment. In addition, its black dust tends to end up on shoes, clothing, and patio furniture.

Acrylic coated with antimicrobial protection

As the name suggests, this type offers antimicrobial protection. Antimicrobial protection is achieved through Microban technology to block bacteria and microbes that cause unpleasant smells and stains.

Zeolite

Zeolite infill is a 100% natural child- and pet-safe volcanic mineral with moisture-absorbing properties. Many pet owners prefer this type. It offers a similar function to cat litter as its negatively charged honeycomb molecular design makes it stand out from other infills. This allows it to absorb pet urine and trap the ammonia gases that cause the unpleasant odor.

How to choose the infill

Before purchasing a particular infill, consider the following:

  • Consider how the turf will be used or applied.

  • Check for product certification, as generic types typically cause weeds.

  • Get the infill applied professionally, as grass insurance may not cover the lawn if you self-install the infill.
