Keeping playground surfacing safe isn't a once-a-year task. Depth drops, contamination builds, and compaction happens quietly in high-traffic zones long before an injury or failed inspection makes it obvious. This checklist gives facility managers and contractors a structured, season-by-season framework to catch problems early, document findings, and know exactly when to top off, replace, or close equipment.

## Why Surfacing Inspection Is Non-Negotiable

ASTM F1292 and CPSC guidelines tie fall-height protection directly to loose-fill depth. Most engineered wood fiber and rubber mulch products require a minimum of 9 inches of uncompressed depth to protect against falls from 7 to 10 feet. Once depth drops below specification, you're exposed -- legally and operationally. Regular inspection closes that gap.

## Universal Inspection Items for Every Visit

Before seasonal specifics, every inspection covers these baseline checks:

1. **Depth at multiple measurement points** -- minimum 3 per fall zone: under equipment (swings, slides, climbers), at landing zones, and at the perimeter.
2. **Displacement from use zones** -- look for surfacing that has migrated outside the fall zone boundaries defined by your fall-height spec.
3. **Edge containment integrity** -- check that borders or timbers are holding material in place and aren't rotting, cracking, or shifting.
4. **Contamination scan** -- look for glass, metal, animal waste, trash, and standing water pooling in low spots.
5. **Compaction in high-traffic zones** -- probe the top 3 inches under swings and at slide exits; compacted material doesn't protect like loose fill.
6. **Drainage condition** -- saturated or muddy zones indicate drainage failure that accelerates compaction.

## Depth Measurement Protocol for Playground Surfacing Inspection

**Where to measure:** At least 3 points per fall zone. Prioritize directly below swing seats and at the base of slide exits. Include at least one perimeter point per zone.

**Tool:** A stiff ruler or depth probe. Use a CPSC-recommended depth gauge for precision.

**What to record:** Location (labeled photo or diagram), measured depth at each point, date, inspector name, weather conditions, and whether action is warranted based on the decision table below.

If any single measurement falls below the required minimum for adjacent equipment's fall height, flag it for immediate action.

## Seasonal Playground Surfacing Inspection Checklist

### Spring (March/April) -- Your Most Critical Inspection

Spring is your biggest inspection of the year. Winter damage concentrates problems.

- [ ] Full depth measurement at all fall zones
- [ ] Check for freeze/thaw heave that displaced edging or timbers
- [ ] Clear debris (leaves, sticks, winter sand or salt) from surface
- [ ] Inspect for mold or fungal growth from prolonged moisture
- [ ] Assess compaction after months of snow load
- [ ] Verify drainage channels are clear and functioning
- [ ] Top off any zone below minimum depth before reopening for the season

### Summer (June/July) -- Peak Use, Accelerated Wear

- [ ] Depth check at all high-traffic zones every 4 to 6 weeks
- [ ] Spot-check displacement after heavy-use weekends or events
- [ ] Check for contamination weekly (trash, debris, animal waste)
- [ ] Inspect edging for UV degradation or impact loosening
- [ ] Redistribute perimeter-collected material before ordering a top-off

### Fall (September/October) -- Pre-Winter Baseline

- [ ] Full depth measurement at all fall zones
- [ ] Remove fallen leaves before they mat and create contamination risk
- [ ] Top off any zones approaching minimum depth before winter
- [ ] Document current state as your pre-winter baseline
- [ ] Inspect edging for root heave or early frost movement

### Winter (December/February) -- Monitor and Plan

- [ ] Visual check after significant snowfall for edging or drainage issues
- [ ] Verify surfacing isn't redistributed by plowing operations
- [ ] Keep records updated for CPSC compliance continuity
- [ ] Plan spring top-off orders based on fall baseline measurements

## Decision Framework: Top-Off vs. Replacement vs. Closure

| Condition | Action |
|---|---|
| Depth 20 to 25% below minimum at any fall zone point | Schedule top-off within 30 days |
| Depth at or below minimum at any point | Top off before reopening or within 7 days |
| Depth below minimum at multiple zones | Full top-off; assess for replacement |
| Heavy compaction with no give in top 2 inches | Full surface replacement -- top-off won't restore protection |
| Contamination present (glass, metal, waste) | Close equipment immediately; decontaminate before reopening |
| Edging failure allowing material to escape fall zone | Repair edging before next use; top off displaced zone |
| Visible decomposition or fines accumulation | Schedule G-max/HIC testing or professional assessment |
| Consistent standing water in fall zones | Remediate drainage before any surfacing work |

## Documentation Requirements

Documentation isn't paperwork overhead. It's your proof of due diligence if someone gets hurt. Keep the following for every inspection:

- Dated inspection form with inspector name and signature
- Depth measurements at labeled locations (photo or diagram)
- Weather conditions at time of inspection
- Actions taken or scheduled as a result
- Vendor receipts for material purchased and installed
- Pre and post measurements when top-off or replacement is performed

Keep records for a minimum of 5 years. Store them where your risk management team can retrieve them fast -- a shared digital folder beats a filing cabinet every time.

## When to Schedule G-Max/HIC Testing vs. Visual Inspection

**Visual inspection is sufficient when:**
- Surfacing is less than 3 years old
- No fall or injury incident has occurred
- Depth measurements meet spec at all points
- Material shows no significant decomposition

**Professional G-max/HIC testing is warranted when:**
- A fall injury has occurred or been reported
- Surfacing is 3 or more years old with visible compaction or decomposition
- Material has exceeded the manufacturer's recommended replacement cycle
- A liability insurance renewal or regulatory audit is pending

G-max measures surface impact attenuation. Visual inspection can't substitute for it once surfacing condition is in question.

## Frequently Asked Questions

**How often should I inspect playground mulch?**
Do a full inspection in spring and fall, with monthly depth checks during peak summer use. After significant rain, an incident, or a heavy-use event, run a spot check on depth and contamination.

**What's the minimum acceptable depth for playground mulch?**
CPSC guidelines tie minimums to fall height. For a 7-foot fall height, you need at least 9 inches of uncompressed engineered wood fiber or double-shredded bark. Check your material spec against the fall height of each piece of equipment on site.

**Can I redistribute displaced mulch instead of ordering new material?**
Yes -- redistribute from low-use zones to high-use fall zones as a short-term fix. But redistribution doesn't add volume to the system. If total volume is down, order a top-off.

**What triggers an immediate closure vs. a scheduled repair?**
Close equipment immediately for any contamination (glass, metal, animal waste) or if depth is at or below the absolute minimum for the fall height. Schedule a repair when depth is approaching minimum (within 20 to 25%) or edging is failing but hasn't yet caused a fall zone shortfall.
