If you're choosing a surface for a playground, garden, equestrian area or landscaping project, wood bark is often the first thing people think of. It looks natural, it's familiar, and it's widely available. But there are two rubber alternatives worth knowing about, rubber chippings and rubber bark mulch, and when it comes to longevity, they both leave wood bark well behind.
This guide runs through the key differences to help you make the right call for your project, your budget, and the long term.
How Long Do Rubber Chippings Last?
Rubber chippings are made from recycled tyres, which means they're built to last. They don't rot, they don't break down, and they don't absorb moisture, so the UK's wet winters and frosty spells have very little effect on them.
With basic upkeep, rubber chippings typically last 10–20+ years, even in high traffic areas like school playgrounds or busy equestrian yards. The rubber stays springy, keeps its colour, and continues performing well throughout that time.
That durability comes down to a few simple facts:
- Rubber doesn't decompose like organic material
- It doesn't compact into the ground over time
- It's resistant to frost, rain and UV exposure
- It won't develop mould or fungus
What About Rubber Bark Mulch?
If you like the look of traditional bark but want the durability of rubber, rubber bark mulch is worth a look. Made from recycled forklift truck tyres, it's 100% wire free and closely mimics the appearance of natural bark; available in brown, red, green, grey, blue and black.
Like rubber chippings, it doesn't rot, compact or absorb moisture, and it carries the same long-term lifespan. It can be laid loose or bonded with resin for a firmer finish, which makes it a versatile option for gardens, decorative areas, play areas and paths.
How Long Does Wood Bark Last?
Wood bark is a natural material, and that's both its appeal and its limitation. It will eventually break down, no matter the quality.
In practical terms:
- High traffic areas (school playgrounds, public parks): 1–2 years before it needs replacing
- Low traffic areas (garden borders, quiet paths): 2–3 years at most
Once bark starts to deteriorate, it compacts into the ground, loses its colour, and can develop mould or fungus. The cushioning effect reduces significantly, which matters if it's being used as playground safety surfacing. At that point, it needs topping up or full replacement.
Longevity at a Glance
| Feature | Rubber Chippings | Rubber Bark Mulch | Wood Bark |
|---|---|---|---|
| Lifespan | 10 - 20+ years | 10 - 20+ years | 1 - 3 years |
| Rot / decomposition | Does not rot | Does not rot | Rots naturally |
| Colour retention | Excellent | Excellent | Fades quickly |
| Maintenance | Very low | Very low | High |
| Compaction | Does not compact | Does not compact | Compacts into soil |
| Weather resistance | All-weather, frost-proof | All-weather, frost-proof | Absorbs water, breaks down |
| Natural bark appearance | No | Yes | Yes |
| Wire Free | - | Yes | N/A |
Which Works Out Cheaper Over Time?
Wood bark costs less upfront, that's true. But because it needs topping up every 6–12 months and full replacement every couple of years, those costs add up quickly.
A simple example: over a 10-year period, you could be replacing wood bark five times or more. Rubber chippings or rubber bark mulch, bought once, will still be performing at year ten.
Most customers find that rubber pays for itself within three to four years, and continues to deliver long after that.
Day-to-Day Maintenance
Rubber chippings and rubber bark mulch need very little attention. An occasional rake to redistribute the surface, a brush or blow to clear leaves and debris, and a hose down if needed. That's about it. No seasonal top-ups, no decomposition to manage.
Wood bark is more demanding. It needs regular topping up to maintain depth, monitoring for mould in damp conditions, and full replacement on a fairly frequent cycle. If it's being used as playground safety surfacing, degraded bark also means reduced fall protection, which means maintenance isn't just a cosmetic concern.
What About Playgrounds Specifically?
For playground use, longevity and safety are directly linked. Both rubber chippings and rubber bark mulch are HIC-certified (tested to BS EN 1177), which means they've been independently assessed for fall protection. Crucially, that protection stays consistent because rubber doesn't compact, the depth you install is the depth you keep.
Wood bark, by contrast, compacts over time. A depth that was adequate at installation may not meet safety standards a year or two later. It can also hide debris like stones or sharp sticks, and becomes slippery when wet.

So, Which Should You Choose?
For short-term projects or situations where upfront cost is the overriding factor, wood bark can work. But for most applications, playgrounds, gardens, equestrian areas, public spaces, rubber is the better long-term choice.
If you want standard rubber loose fill, our playground rubber chippings are a good starting point. If you'd prefer something that looks more like traditional bark, our rubber bark mulch gives you that aesthetic without the maintenance headaches. Not sure which suits your project?
