What Is Infill In Artificial Turf And Why Does It Matter So Much?
When homeowners think about artificial turf, they picture the blades.
But the real performance secret?It’s what sits between those blades.
That material is called infill and it’s absolutely essential to how your turf looks, feels, drains, and lasts.
At Waterloo Turf, we always start with the “why,” because infill isn’t just filler. It’s the foundation of performance.
What Is Infill And Why Is It Necessary?
Infill is the granular material (most commonly silica sand or specialty blends) that’s spread between turf fibers after installation.
Without infill:
- Turf blades would flatten
- The surface would shift or wrinkle
- Drainage would suffer
- The lawn would look unnatural
- Backing would wear out faster
Infill adds weight and stability while mimicking the density of natural soil. It keeps your lawn upright, resilient, and realistic.
It’s not optional. It’s engineered.
What Does Infill Actually Do For Performance?
Infill impacts three major things:
Performance: It helps blades stand upright for that full, natural look. It also adds structure so your turf performs under daily foot traffic.
Durability: Infill protects the backing from UV exposure and friction, extending the lifespan of your turf system.
Feel Underfoot: It adds cushioning and comfort so whether you’re barefoot, playing with kids, or hosting guests, it feels soft but stable.
At Waterloo Turf, we use graded infill products like Wonderfill to ensure turf performs like a pro field: soft, resilient, and built to last.
What Are The Different Types Of Infill?
Not all infill is created equal.
Here are the most common options:
Silica Sand
- Affordable
- Excellent drainage
- Non-toxic
- Versatile for most applications
Crumb Rubber
- Very cushioned
- Can retain heat
- Controversial for some homeowners
Organic Infill (Cork, Zeolite, etc.)
- Eco-friendly
- Helps control odors
- Often used in pet systems
Each type differs in:
- Weight
- Cooling properties
- Sanitation performance
- Cost
We keep it simple for homeowners: choose based on how you use your yard.
At Waterloo Turf, we recommend graded infills like Wonderfill because they provide balanced performance without unnecessary tradeoffs.
How Does Infill Affect Heat, Drainage, And Comfort?
Infill plays a major role in how your yard feels year-round.
Heat: Lighter-colored sands reflect more heat than dark rubber materials. This makes a noticeable difference in hot Texas summers.
Drainage: Infill creates space between fibers, allowing water to flow vertically through the turf without clogging.
Comfort: It adds padding that softens impact ideal for kids, pets, and everyday use.
Our infill systems are selected specifically to:
- Drain quickly
- Reduce heat retention
- Stay comfortable underfoot
It’s all about balanced performance.
Is Infill The Same For Pet Turf, Putting Greens, And Landscape Turf?
No, and it shouldn’t be.
Pet Turf: Uses antimicrobial infill (often zeolite-based) to control odor and neutralize bacteria.
Putting Greens: Require finer, consistent sand to allow smooth, true ball roll.
Landscape Turf: Typically uses standard silica sand for durability and natural appearance.
At Waterloo Turf, we customize infill based on how the space will be used. No one-size-fits-all solutions.
How Does Infill Help With Odor Control For Pet Owners?
For pet owners, infill is critical.
Antimicrobial infill options:
- Neutralize urine bacteria
- Reduce odor buildup
- Allow quick liquid absorption
- Prevent mold growth
Paired with proper drainage and occasional rinsing, this keeps yards sanitary and fresh long-term.
It’s a game-changer for families who want clean, hassle-free outdoor space.
What Happens If Infill Is Skipped Or Installed Incorrectly?
This is where cheap installs fail.
Skipping infill leads to:
- Flattened blades
- Poor drainage
- Faster backing wear
- Reduced lifespan
Improper installation causes:
- Uneven surfaces
- Lumps and low spots
- Inconsistent appearance
- Water pooling
At Waterloo Turf, proper infill application is non-negotiable. It’s a core part of delivering turf that performs exactly as promised.
Does Infill Need Maintenance?
Yes, but it’s minimal.
Over time, infill can:
- Compact slightly
- Shift in high-traffic areas
- Wash away in small amounts
We recommend:
- Annual inspection
- Power-broom redistribution as needed
- Top-ups every 2–3 years in heavy-use areas
We also offer maintenance plans to keep your system performing long-term.
How Can You Tell If An Installer Is Using The Right Infill?
Ask questions.
- What type of infill are you using?
- How many pounds per square foot? (Typically 1–2 lbs for standard installs.)
- Is it antimicrobial for pet areas?
- Can I see a sample?
- How do you ensure even distribution?
Professional installers should confidently explain their infill choice and why it fits your yard.
The Bottom Line

- How it handles pets
