Loose-Fill vs Synthetic Surfacing

Updated: Jul 5

Total Cost of Ownership:(NZD)


Selecting the right playground surfacing means considering not just the initial installation cost, but the total cost of ownership (TCO) over the lifespan of the surface. TCO includes maintenance, testing, performance, and eventual replacement costs — all critical for budgeting and long-term safety planning.


Both loose-fill and synthetic surfaces are compliant under NZS 5828 and EN 1177 when properly installed and maintained. However, they offer very different cost and maintenance profiles.


💰 Initial Installation Costs

Surface Type

Typical Cost per m² (Installed)

Loose-fill (e.g. woodchip, bark, sand)

$35–$60 NZD

Synthetic (e.g. wet pour rubber, rubber tiles, bonded mulch)

$200–$350 NZD

Loose-fill is often chosen for community parks or ECEs with tighter capital budgets. Synthetic surfaces are ideal for high-use urban areas, inclusive playgrounds, or where minimal maintenance is a priority.


🛠️ Maintenance Requirements

Loose-fill:

  • Requires regular topping up (approx. 100 mm per year)

  • Needs raking, re-levelling, decompaction

  • Prone to material loss, compaction, contamination

  • Higher maintenance burden over time


Synthetic:

  • Low maintenance (cleaning, moss/algae control)

  • Must be impact tested every 2 years to confirm Critical Fall Height (CFH)

  • Durable and consistent performance when installed correctly

  • Resistant to displacement and vandalism


⏳ Lifespan and Replacement

Surface Type

Typical Service Life

Full Replacement Cycle

Loose-fill

Annual top-ups / 8–10 years full

Replace every 8–10 years

Synthetic

10–15 years

Replace at 12–15 years based on testing and wear

📌 Summary Comparison

Consideration

Loose-Fill

Synthetic

Budget Friendly (CapEx)

✅ Yes – Low upfront cost

❌ No – High upfront investment

Predictable Long-Term Cost

❌ Variable, based on usage

✅ Predictable with periodic testing

Maintenance Burden

❌ High (manual top-ups, raking)

✅ Low (cleaning, periodic testing)

Wheelchair Accessibility

❌ Poor

✅ Excellent

Visual Appeal

⚠️ Can degrade over time

✅ Clean, professional appearance

Ideal For

ECEs, natural parks, community use

High-use parks, schools, inclusive play

Recommendation

  • Loose-fill is suitable for smaller playgrounds or where natural aesthetics are important and maintenance resourcing is available.

  • Synthetic surfacing offers superior accessibility, durability, and consistency — ideal for schools, councils, and inclusive playgrounds, especially when long-term cost predictability and accessibility are key.
