Quick answer: Replace a rubber mat when it can no longer lie flat, grip the floor or drain properly, or when the rubber itself has cracked, hardened, swollen or torn. Curled or lifting edges are the most urgent sign, because they turn a safety mat into a trip hazard. None of the product pages for the mats in this guide give a fixed lifespan, so judge each mat by its condition, not its age. The checklist below gives your team a quick monthly inspection and a clear rule for when to repair, move or replace.
Rawlins has supplied cleaning equipment, chemicals and matting to UK businesses since 1981. This guide is for facilities managers, site leads, kitchen managers and cleaning supervisors who look after rubber matting in workshops, kitchens, wet areas and entrances.
Why rubber mats need a replacement rule
Rubber mats wear slowly, so it is easy to stop noticing them. A mat that was put down to reduce slips can, once it is worn, become a hazard in its own right. HSE's slips and trips hazard-spotting checklist (CK4) asks whether there are trip hazards in the area, and lists "mats with curled up edges" as one example. Its suggested action is to "fix down mat edges or replace if necessary".
The law sets the standard for the floor, not the mat. Regulation 12 of the Workplace (Health, Safety and Welfare) Regulations 1992 says floors must not have holes or be uneven or slippery so as to expose anyone to a risk to their health or safety. Once a mat is on the floor, it is part of that floor surface, so a damaged mat is a floor problem.
Monthly checks
A monthly walk-round, plus a quick look whenever mats are lifted for cleaning, catches most problems early. Use the table below as your inspection sheet.
| Check | What to look for | Action |
|---|---|---|
| Edges | Curling, lifting or edges that catch a trolley wheel or toe | Refit or fix down the same day; replace if the edge will not lie flat |
| Surface | Cracks, splits or crazing on the top surface | Replace if cracks run through the mat or keep spreading |
| Feel | Rubber that has gone hard, brittle or sticky | Replace, and review the chemicals used in that area |
| Shape | Swelling, bulging or a mat that has grown out of its space | Check for oil or chemical exposure; replace if it no longer lies flat |
| Drainage holes | Torn webbing between holes, or holes packed with debris | Clean blocked holes; replace if the webbing is torn across the walking line |
| Grip on the floor | Mat creeping, sliding or rocking when stepped on | Clean the floor and the mat underside; replace if it still moves |
| Grip underfoot | Smooth, polished areas where the surface pattern has worn away | Replace, or move to a lower-traffic dry area |
| Odour | A persistent smell that returns after a thorough clean | Check for trapped soil underneath; replace if it persists |
How to check quickly
Walk the main walking line first, because that is where wear shows up soonest. Lift one corner of each mat to see the underside and the floor beneath. Flex a small section of the mat by hand: healthy rubber bends and recovers, while old or chemically damaged rubber may crack, stay bent or feel tacky.
Signs of chemical damage
Chemical damage is a common reason for early replacement, especially in kitchens and workshops. The signs are swelling, softening, stickiness, colour change and surface cracking. A mat that swells may lift at the edges or ripple, which creates a trip hazard even if it looks clean.
Different rubbers resist different substances. Rawlins' Superscrape non-slip rubber mats are heavy-duty nitrile rubber, and the product page describes them as ideal for kitchen and industrial areas where grease may cause slips. The Heavy-Duty Anti Slip Comfort Mat is made from a rubber blend that its product page says has better-than-average resistance to oil and chemicals. If a mat that is not oil resistant has been sitting in an oily area, swelling is a sign it is in the wrong place, not just that it is old.
Cleaning chemicals matter too. If mats are wearing out faster than expected, check what is being used on them and at what dilution. Our guide to rubber mats and cleaning chemicals explains what to ask the manufacturer before you change products.
Trip hazards: curled and lifting edges
Curled edges deserve their own check because they cause trips, catch trolley and cage wheels, and get worse each time they are kicked or rolled over. Common causes include mats laid on a wet floor, mats folded or rolled for storage, swelling from oil or chemicals, and mats cut to fit without a bevelled edge.
The Heavy-Duty Anti Slip Comfort Mat has anti-trip bevelled edges, and its product page says bevelled edges are available even on cut lengths. Where a mat has bevelled edges and they still curl, the mat itself may have distorted. HSE's advice is simple: fix the edge down or replace the mat. Do not tape over a curled edge as a long-term fix, because tape lifts, collects dirt and creates a new edge to trip on.
Repair or replace?
Usually fixable
- Debris packed into drainage holes: lift, scrub and rinse the mat, then let it dry before relaying.
- A mat creeping on the floor: clean and dry both the floor and the underside, then relay.
- A smell from trapped soil: clean underneath more often. Our guide to why new rubber mats smell covers new-mat odour.
- A mat in the wrong place: move a mat that is not oil resistant out of oily areas.
Time to replace
- Edges that will not lie flat after refitting.
- Cracks or splits across the walking line.
- Torn webbing between drainage holes where heels or wheels can catch.
- Rubber that has hardened, gone sticky or swollen out of shape.
- A surface worn smooth so it no longer gives grip.
When you replace, match the mat to the area. The Unimat Workplace Rubber Mat has open holes for drainage and, according to its product page, meets the DIN 51130 slip resistance test, which suits wet or oily industrial and kitchen floors.

Record-keeping
A simple log shows that mats are being checked and acted on, which supports your slips and trips risk assessment. For each mat, record its location, the date checked, who checked it, what was found and what was done. Give each mat a short reference, such as "Kitchen 2" or "Workshop line A", so that repeat problems in one spot are easy to see.
If the same location keeps wearing out mats early, treat it as a signal. It may need a different type of mat, a different cleaning chemical or a change to how trolleys cross it.
Frequently asked questions
How long do rubber mats last?
There is no single answer, and the product pages for the mats in this guide do not give a lifespan. Life depends on footfall, wheeled traffic, oils, chemicals and cleaning. Inspect monthly and replace on condition.
Why is my rubber mat cracking?
Cracking usually comes from age, heavy wear, or contact with oils or chemicals the rubber does not resist. Check what is spilled and used for cleaning in that area. Replace the mat if cracks cross the walking line.
Can a curled mat edge be fixed?
Sometimes. Relaying a mat on a clean, dry floor can help. HSE's checklist says to fix down mat edges or replace if necessary. If the edge will not lie flat, replace the mat.
Who should inspect workplace mats?
Anyone trained to use the checklist can do it, such as a cleaning supervisor, kitchen manager or site lead. Make it part of an existing routine, such as the weekly deep clean, and record each check.
