Surfacing & softfall

The surface beneath a playground is its single most important safety feature — it's what protects a child when they fall. It's also one of your biggest budget and maintenance decisions. Here's how to choose well.

Surfacing & softfall

At a glance

  • Mulch · sand · wet-pour · synthetic turf
  • Tested to HIC ≤ 1000 (AS 4422)
  • Loose-fill installed at 300mm+
  • Wet-pour depth set by fall height

Why surfacing matters most

Most serious playground injuries are caused by falls onto hard ground. Compliant softfall surfacing absorbs that impact, and under AS 4422 it must be matched to the equipment's critical fall height so it keeps the Head Injury Criterion at 1000 or below. Get the surface right and you've addressed the biggest risk on site.

Your options at a glance

There's no single 'best' surface — each balances cost, feel, accessibility and upkeep differently.

  • Certified playground mulch — natural look, lowest cost; needs periodic topping up to keep its depth
  • Sand — popular for early childhood and sensory play; raked and kept clean
  • Wet-pour rubber — seamless, custom colours and patterns, wheelchair accessible; higher upfront cost, low maintenance
  • Synthetic turf with a shock pad — soft natural appearance, accessible, hard-wearing; mid-range cost

Matching the surface to the fall height

Depth and thickness aren't arbitrary — they're driven by how far a child could fall. Loose-fill materials like mulch and sand are typically installed at 300mm or more, compacted, and need topping up over time as they displace and break down. Wet-pour rubber is laid thicker as the fall height increases, with the exact build-up determined by impact testing.

Cost vs maintenance

Loose-fill surfaces are cheaper to install but carry an ongoing maintenance task — raking, decompacting and topping up to maintain compliant depth. Wet-pour and turf cost more upfront but ask very little of you afterwards. Over a playground's life, the 'cheapest' option isn't always the lowest total cost, so it's worth weighing both.

Accessibility & drainage

If inclusive access matters to you, firm surfaces like wet-pour and turf allow prams and wheelchairs right up to and through the playground, whereas loose-fill is harder to traverse. Whatever you choose, proper base preparation, drainage and edging are what keep a surface performing — and looking good — for years. We'll specify the right surface for your equipment, site and budget as part of your design.

Frequently asked

Which surface is the cheapest?

Certified playground mulch is usually the lowest upfront cost, but remember it needs topping up periodically to stay at compliant depth.

What's best for a childcare centre?

It depends on the play value you want — sand is wonderful for sensory play, while wet-pour gives a seamless, accessible, low-maintenance surface. Many centres mix both.

How often does mulch need topping up?

It varies with traffic and weather, but loose-fill displaces and compacts over time, so plan to check depth regularly and replenish as needed.
