Thousands of children are treated in UK A&E departments each year following falls from garden play equipment. The right safety surface dramatically reduces the risk of serious injury. If you have — or are planning — a swing set, climbing frame, or trampoline, this guide covers everything you need to know.
Do You Need a Safety Surface in Your Garden?
Legally, private residential gardens are exempt from EN1177 requirements. But garden grass provides almost no impact attenuation — certainly not enough to protect a child falling from a 1.5m platform. If your play equipment has any accessible point above 600mm, a proper safety surface makes a real difference to injury outcomes.
For more on EN1177 and what the safety ratings mean, see our EN1177 safety standard.
How Much Area Do You Need to Cover?
The surfaced area must extend beyond the equipment footprint into the fall zone:
- Swings: Extend twice the height of the top bar in front and behind; 1.5m to each side
- Climbing frames / slides: 1.5–2.0m beyond all sides of the equipment footprint
- Trampolines: Minimum 1.5m around the perimeter (quality enclosure nets reduce risk but don't eliminate it)
Which Thickness Do You Need?
| Highest Accessible Point | Tile Thickness |
|---|---|
| Under 1.0m | 25mm |
| Up to 1.5m | 40mm |
| Up to 2.0m | 50mm |
| 2.0m+ | 65mm |
If in doubt, go thicker. The price difference between tile thicknesses is modest compared to the additional protection provided.
How to Install Tiles in Your Garden
Garden installation is one of the simplest applications for rubber tiles — most complete in half a day. See our full installation guide for step-by-step detail. For gardens:
- Mow grass short or remove if installing on bare earth
- Lay a weed suppressant membrane to prevent growth through joints
- Dry-lay tiles butted together tightly — no adhesive needed for domestic garden use
- Secure edging strips with garden stakes or tent pegs
Do garden playground tiles need to be fixed down?
For domestic garden use under standard play equipment, dry-laying (no adhesive) is perfectly adequate. The tiles' weight keeps them in position. Securing perimeter edging prevents tiles migrating outward under heavy use.
What's the best surface to put under a swing set?
40mm rubber playground tiles provide the best combination of protection, durability, and ease of installation for a standard swing set (top bar height 1.5m or under). They outperform grass, bark, sand, and rubber mulch on all practical measures for most garden installations.
Can rubber tiles go under a trampoline?
Yes — and they're one of the best options. Lay tiles under and around the trampoline's perimeter (minimum 1.5m beyond the frame). Choose 40–50mm thickness. The firm surface also gives the trampoline legs a stable base, reducing rocking on uneven grass.
Maintenance
Garden rubber tiles are extremely low-maintenance:
- Sweep off leaves and debris regularly
- Jet wash once or twice a year
- Check tiles after winter for frost heave or shifting
- Replace any cracked tile promptly (easy — just lift and swap)
How Long Will They Last?
In a typical garden environment, quality rubber playground tiles last 10–20 years. They are UV-stable, frost-proof, and unaffected by UK weather. Unlike bark chippings (which rot, attract pests, and need annual topping up) or sand (which disperses and gets muddy), rubber tiles are a one-time purchase.
