How Deep Should Rubber Chippings Be for a Play Area? UK Guide

Last updated: April 2026

Getting the depth of rubber chippings right is not just about aesthetics — it's a safety-critical decision. Install too shallow and your play area is not BS EN 1177 compliant. This guide explains the depth requirements, how to maintain them, and what happens when you get it wrong.

Why Depth Matters: BS EN 1177 Compliance

BS EN 1177 requires playground surfaces to protect children from life-threatening head injuries in falls from equipment. For rubber chippings, the impact attenuation provided is directly dependent on depth — a thicker layer absorbs more impact energy.

The standard establishes minimum depths for rubber chippings based on the critical fall height (CFH) of the equipment:

Equipment CFH	Minimum Rubber Chippings Depth	Recommended Depth (with buffer)	Top-Up Trigger
Up to 0.6m (small toddler equipment)	50mm	75mm	Below 50mm
Up to 1.0m	75mm	100mm	Below 75mm
Up to 1.5m	100mm	125mm	Below 100mm
Up to 2.0m	150mm	175mm	Below 150mm
Up to 3.0m	200mm	225mm	Below 200mm

Always verify depth requirements with the specific BS EN 1177 test data for your product.

How to Measure Depth

Depth is measured as the loose, uncompressed depth — not the compressed depth after use. Use a depth probe (a marked rod or ruler) inserted vertically into the chippings to the sub-base. Take multiple measurements across the play area, particularly in high-traffic zones under swings and at the base of slides where chippings are displaced most rapidly.

Document every measurement with date and location — this record is essential evidence of due diligence if an injury incident occurs at your play area.

How Often Does Depth Decrease?

The rate of depth loss depends on:

• Play intensity: A busy school playground under a popular climbing frame will displace chippings within days
• Equipment type: Swings and slides displace chippings more rapidly than static equipment
• Area size vs equipment: Larger surface areas around equipment displace chippings more slowly
• Containment edging: Good containment reduces loss significantly

As a general guide, plan to top up active school play areas every 4–8 weeks during term time. Domestic garden play areas may only need topping up twice per year.

Practical Maintenance Schedule

Weekly Checks

• Visual inspection of chipping depth in highest-use areas
• Rake displaced chippings back under equipment fall zones
• Check containment edging is intact

Monthly Checks

• Formal depth measurement at all equipment fall zones — record results
• Top up where depth is below minimum requirement
• Remove any debris, foreign objects or glass

Annual Audit

• Full audit of depth across entire play area
• Check for fragmentation — heavily fragmented chippings lose impact attenuation
• Consider impact attenuation testing by accredited body if equipment CFH is high
• Review and update inspection records

Rubber Chippings vs Wetpour vs Rubber Tiles: Which is Best for Play Areas?

Surface Type	Installation Cost	Maintenance	Lifespan	Best For
Rubber Chippings	Low–Medium	Regular depth checks, top-ups	8–12 years (topping up)	Schools, council parks, large areas
Wetpour Rubber	High	Low — inspect for cracks/damage	10–15 years	Permanent installations, disabled access required
Interlocking Rubber Tiles	Medium	Very low — check joints	10–20 years	Trim areas, smaller play zones

Installing at the Right Depth

When installing rubber chippings, install to 25–30mm above the required minimum depth. This provides a buffer for initial compaction and dispersal, ensuring compliance is maintained from day one.

Install containment edging before laying chippings. The edging height should match the chipping depth — edging that is too low allows chippings to spill over at the edges, reducing depth in the critical fall zone near the equipment.

Cost of Rubber Chippings: UK Price Guide 2026

Rubber chippings for play areas typically cost:

• 50mm depth installation: £8–12/m²
• 100mm depth installation: £15–22/m²
• 150mm depth installation: £22–32/m²
• 200mm depth installation: £28–42/m²

Prices vary by supplier, quantity, and whether installation is included. Free delivery is available on larger orders. View current rubber chippings pricing.

Frequently Asked Questions

What depth of rubber chippings do I need for a 2m fall height?

150mm minimum. We recommend installing to 175–200mm to allow for initial dispersal while maintaining BS EN 1177 compliance.

Do rubber chippings need replacing regularly?

Topping up yes — full replacement less frequently. Rubber doesn't biodegrade, so depth maintenance through periodic top-ups is the main ongoing requirement. Budget for 1–2 top-ups per year on active school play areas.

Can I mix rubber chippings with bark chip?

Not for compliant play areas. Mixed surfaces have inconsistent impact attenuation performance. Maintain a single-material surface at the certified depth.

How much do rubber chippings cost per m²?

Typically £15–35/m² depending on depth required and supplier. Contact Rubberco for bulk pricing on large play area installations.

Are rubber chippings safe for children and pets?

Play-area certified rubber chippings are manufactured to EN 71-3 (toy safety) — free from harmful heavy metals and chemicals. They are also pet-friendly and non-toxic. Always specify play-area grade, not industrial rubber waste.

How long do rubber chippings last?

With regular topping up to maintain depth, rubber chippings can last 8–12 years before fragmentation requires full replacement. This compares favourably to bark chip, which typically needs full replacement every 1–2 years as it biodegrades.
