Map infill consistency before deciding what the field needs.
Infill supports fibers and contributes to the playing-surface system. Heavy-use areas can lose or redistribute infill over time. Depth checks help identify where correction or top-off may be appropriate.
Signs this service may be needed
Unsupported or matted fibers, displaced material in high-traffic zones, visible low spots or uncertainty about where redistribution or top-off is needed.
What STMG evaluates
Infill-depth evaluation becomes relevant when high-use zones look inconsistent, fibers appear less supported, or an owner needs measurements before redistribution or top-off. Multiple locations provide more useful context than a single reading.
Typical process
Measurements are taken at documented representative and high-use locations, then reviewed against the known field system, prior records and applicable guidance. The work can be paired with visual inspection and mapping.
Use repeatable locations instead of a single spot check.
A defensible infill-depth scope should use multiple documented locations, emphasize high-use zones and include representative lower-use areas for context. Measurements are most useful when the field system and prior maintenance history are known. The result should identify where redistribution or compatible top-off material may be warranted rather than forcing one universal depth target onto every field.
Relationship to other field care
Measurements should be interpreted in context of the field system and manufacturer guidance; STMG avoids universal target-depth claims that may not apply to a specific system.
The service can be scoped independently or connected to inspection, corrective work and a recurring program when the field evidence supports that approach.
Documentation
A report can show measurement locations, observed distribution patterns, areas for follow-up and whether redistribution or compatible material should be considered.
Who uses this service
School districts, sports complexes and multi-field owners request this service when field use or visible infill movement suggests a condition-based adjustment.
Frequently asked questions
What indicates a need for infill depth testing?
Unsupported or matted fibers, displaced material in high-traffic zones, visible low spots or uncertainty about where redistribution or top-off is needed.
Can this work be combined with an inspection?
Yes. An inspection can establish the field condition and define whether infill depth testing should stand alone or be paired with other maintenance.
Will STMG review manufacturer guidance?
Available field-system, warranty and manufacturer maintenance information should be reviewed before selecting methods or compatible materials.
What documentation may be provided?
A report can show measurement locations, observed distribution patterns, areas for follow-up and whether redistribution or compatible material should be considered.
