What changes the amount of infill you need

You are setting up a performance system for pets, not just topping off turf. The right infill load depends on the turf profile and how hard your dogs play.

  • Pile height and density: Taller, denser blades require more material to support fibers and keep them upright.
  • Traffic and dog size: Multiple or larger dogs increase compaction and odor load, so plan higher totals.
  • Infill type: Zeolite targets ammonia control. Coated antimicrobial sand adds ballast, fiber support, and cleanability.
  • Drainage design: Permeable backing over a well-compacted, free-draining base allows faster flush and less odor retention.
  • Climate and sun: Hot, full-sun sites benefit from coated sand that resists dusting and helps manage surface temps.

Recommended pet infill system

Materials that work

  • Zeolite: Natural mineral that adsorbs ammonia from urine. Ideal as the top layer near the fiber tips.
  • Coated antimicrobial sand: Rounded, dust-minimized, and easy to groom. Delivers ballast and stable footing.
  • Avoid crumb rubber for dog yards due to heat retention and less odor control compared to mineral and coated sand blends.

Coverage guide by pile height

  • 1.0 to 1.25 inch pet turf: Aim for a lighter total load. Favor more zeolite in the blend for daily urine management.
  • 1.5 to 1.75 inch turf: Step up total pounds per square foot. Keep a balanced split between zeolite and coated sand.
  • 1.75 to 2.0 inch turf: Heaviest loads in this range to fully support fibers in active runs and kennels.

Target a visible blade tip exposure of about 0.25 to 0.5 inch after grooming. If blades get buried, remove a little infill and re-broom for proper lift and airflow.

Simple calculator

Formula: Area (sq ft) × chosen lb per sq ft = total pounds. Bag count uses typical 50 lb bags.

  • Example A: 200 sq ft backyard at 2.5 lb per sq ft = 500 lb total. Split roughly half zeolite and half coated sand. About 10 bags total.
  • Example B: 600 sq ft daycare run at 2.75 lb per sq ft = 1,650 lb total. If you lean odor control, place a little more zeolite on top. About 33 bags total.

Pro tip: Apply in two to three lifts, brooming between passes to lock the system tight without choking the blades.

Installation playbook

Apply in lifts

  1. Pre-groom dry turf to stand fibers up.
  2. Broadcast roughly half your target load evenly.
  3. Power broom against the grain until infill settles and fibers lift.
  4. Repeat with the remaining material, finishing with zeolite near the top layer.
  5. Confirm blade tip exposure of 0.25 to 0.5 inch.

Drainage and odor control

  • Use permeable turf over a compacted, open-graded base. Maintain positive drainage away from structures.
  • Rinse high-use zones weekly. Use a pet-safe enzyme cleaner as needed to break down organics.
  • Zeolite can be refreshed by thorough rinsing followed by sun drying.

Safety notes

  • Choose washed, rounded, or coated sands to minimize dust. Wear eye and respiratory protection during installation.
  • Keep infill dry on delivery and before install to avoid clumping.

Maintenance schedule

  • Monthly: Inspect traffic lanes, rake or broom to re-stand fibers, spot rinse potty zones.
  • Quarterly or as needed: Top off light areas with a small addition of zeolite or coated sand, then groom.
  • After heavy storms or play: Re-broom to redistribute infill evenly.

When to adjust your target

  • Increase total load for multiple large dogs, hard cornering, or on taller piles.
  • Reduce slightly for low-traffic patios or very short, dense pet turf where fiber support is easier to achieve.
  • Balance the blend by adding a little more zeolite if odor spikes, or more coated sand if fibers lean or mat.
