Why Infill Is a Big Deal in Any Artificial Grass System
The importance of infill in artificial grass systems can’t be overstated. Think of it as the secret ingredient that gives your turf durability, bounce, and comfort. The infill material is what sits between the blades of turf, helping them stay upright and creating the right amount of cushion and shock absorption underfoot.
Whether you’re installing pet turf, a multipurpose athletic field, or a backyard putting green, the type and quality of infill used can influence:
- Safety and injury prevention
- Drainage and water flow
- Surface temperature
- Turf longevity and blade support
- Odor control in pet areas
Infill Options: Exploring the Most Common Types of Turf Infill
There are multiple turf infill options, and choosing the right one depends on your turf application, location, and goals. Let’s break down the most common types of infill available today.
Crumb Rubber
Crumb rubber is one of the most widely used types of rubber infill. It’s made from recycled tires and offers strong durability and bounce. It’s best for athletic fields that need resilience and heavy foot traffic endurance.
- ✅ Excellent shock absorption
- ✅ Affordable and long-lasting
- ❌ May retain heat and have slight odor in hot climates
Silica Sand
Silica sand is another popular infill material used in both artificial grass lawns and playgrounds. It provides excellent ballast to weigh down the turf and keeps the turf fibers standing upright.
- ✅ Budget-friendly and readily available
- ✅ Great for playgrounds and landscaping
- ❌ Less bounce and less cushion than rubber options
Sand-Rubber Blends
A hybrid infill type combining the two above, sand-rubber blends aim to offer a balance between stability and comfort. They’re often used for community parks and sports fields with mixed usage.
Organic Infill
Eco-friendly options like cork or coconut husks are rising in popularity. They reduce surface temperatures and odor, making them great for pet turf or child play areas.
- ✅ Cooler surface, low environmental impact
- ❌ Requires more frequent maintenance and replacement
How Infill Affects Turf Performance, Safety, and Longevity
Choosing the best artificial grass infill isn’t just about budget—it’s about optimizing the surface for every play, step, or roll. The infill needed for each site depends heavily on how that field is going to be used.
Key Performance Factors:
- Shock absorption for injury prevention
- Vertical blade support to maintain realistic grass appearance
- Enhanced drainage capabilities
- Odor control in high-traffic or pet-heavy areas
- Heat regulation, especially in warmer climates
Recreational Industries works with schools and municipalities to recommend the infill type that offers the safest and most cost-effective return for the environment it will serve.
Artificial Turf Infill and Grass Infill: What’s the Difference?
While the terms artificial turf infill and grass infill are sometimes used interchangeably, they can refer to different applications. Artificial turf infill is more often used for sports or large-scale fields, while grass infill typically applies to artificial grass for landscaping, dog parks, or backyards.
If you’re not sure what infill your artificial turf project requires, start with the question: “What will this area be used for most?”
- Sports → crumb rubber or sand-rubber blends
- Pets → organic infill or antimicrobial rubber
- Landscape → silica sand or pet-friendly mix

Infill Maintenance Tips to Extend Turf Life
Even though artificial grass and artificial turf are known for being low maintenance, the infill used inside your turf system does need occasional attention. Here’s how to protect your investment:
- Rake and brush regularly to redistribute compacted infill
- Top off infill when you see blades flattening
- Monitor drainage after storms or heavy use
- Replace worn-down infill every 2–3 years for high-traffic areas
Doing this helps preserve performance, protects your users, and ensures the turf continues to look and feel great.

Frequently Asked Questions About Synthetic Turf Infill
Why is infill important for artificial grass systems?
The importance of infill for artificial turf goes beyond just holding things in place. Infill is an essential component of all artificial grass systems, helping with shock absorption, supporting the turf fibers, and maintaining an upright position for the blades of artificial grass. It also plays a key role in drainage and reduces the surface temperature of the turf, especially in warmer climates.
What is the best infill to use for artificial grass?
The best infill depends on your specific project. For most turf applications, silica sand infill is great for residential or light-use spaces. Organic infill made from volcanic material is gaining popularity for its cooling properties and eco-friendliness. For athletic fields, the best infill to use may be traditional crumb rubber infill due to its performance and durability.
How does infill help with turf longevity and performance?
Infill helps protect the turf backing from wear, supports the pile height of the turf, and keeps the turf weighted against wind uplift. Infill is also used to prevent matting and flattening of blades, which affects the lifespan of your turf. In short, infill may be the biggest factor in the longevity of your artificial lawn.
Which infill type is right for a sports field or athletic turf?
For a sports field, the infill type you choose must prioritize shock absorption, performance, and durability. Crumb rubber is commonly used for athletic turf, but newer options like organic infill or coated sand are being used to reduce growth of bacteria and lower surface heat.
What are the main types of infill available today?
The main types of infill include:
- Silica sand infill
- Crumb rubber
- Coated sand
- Organic infill made from volcanic ash
- Manufactured sand and regular sand
Each used infill material has pros and cons depending on safety, durability, turf surface, and use case.
How do I choose the right infill material for my turf system?
Start by defining your goal—do you want the best artificial grass infill for pets, play, or sports? Choosing the right infill means balancing durability, performance, odor control (in case of pet urine), and maintenance. The right infill material can reduce upkeep and make your turf safer. For some artificial lawn projects, you’ll want to use a heavier infill to stabilize the blades and keep your turf in place.
Can I install turf without infill?
Technically, yes — but it’s not recommended. Turf without infill tends to mat faster, wears down quicker, and won’t feel or perform as naturally. Even minimal base infill is necessary to support the backing of artificial grass and keep the surface stable.
What infill is used in putting greens or specialty installs?
Putting green infill is often a blend of silica sand and fine particle materials. The goal is to ensure ball roll consistency and a clean, flat surface. Specialty infill is used to reduce bounce and friction while keeping the surface smooth.
Is the turf infill used in pet areas different?
Yes. Pet-friendly turf infill options often include organic infill or antimicrobial coated sand to neutralize odor and reduce the risk of growth of bacteria from pet urine. This makes your synthetic grass cleaner and more hygienic.
What does an artificial turf installer recommend for infill?
A professional artificial turf installer will assess your project’s use, climate, and goals to recommend the best artificial grass infill or artificial turf infill. In general, installers select different infill material depending on whether the turf is for athletic fields, landscaping, or pet use.
How much infill is needed for turf installation?
The infill needed depends on the turf system thickness, pile height of the turf, and how the turf will be used. Heavier-use areas, like synthetic turf fields, require infill at higher density to prevent flattening and extend the turf’s lifespan.
How do I keep the turf in place after installation?
Infill to use to help with anchoring and stability is critical. You’ll want to weigh down the turf by spreading infill made of silica sand, crumb rubber, or another suitable material evenly across your artificial grass.
