Case Study: Primary School Replaces Cracked Playground with Rubber Safety Tiles — Zero Injuries in 18 Months
The Challenge
When headteacher Claire Ramsden walked the playground with the school's premises governor in autumn 2022, the condition of the play surface around the main climbing structure had deteriorated to the point where it could not be ignored. The original wetpour rubber surface, installed in 2011, had cracked across a significant area — not hairline fractures but open breaks of 20-30mm in places, with the surface lifting and separating from the concrete base in several locations.
Three injury reports had been filed in the preceding 18 months, all involving children catching feet or tripping on raised edges of the cracking surface. None resulted in more than a grazed knee, but the school's duty of care obligations required formal documentation and reporting to the governing body. The insurers were notified as a precautionary measure.
An Ofsted inspection in November 2022 noted in feedback that the school's safeguarding documentation referenced the playground surface as a known risk requiring remediation. Under Ofsted's strengthened safeguarding framework, outstanding risks that remained unaddressed between inspection cycles would be scrutinised more closely at any follow-up visit. Ramsden was not willing to carry that risk into the next academic year.
Budget was limited. Any replacement solution needed to be cost-effective without compromising on safety certification.
Why Rubber Matting Direct
The school explored three options: complete wetpour replacement (quoted at £28,000-£32,000), artificial grass over compacted aggregate (£14,000), and interlocking rubber playground tiles. Rubber Matting Direct's EPDM playground safety tiles came in substantially below the wetpour cost, and were certified to EN1177 for a critical fall height of 1.5m — adequate for the climbing frame height at the school.
The interlocking tile format offered a practical advantage: individual tiles can be replaced if they sustain damage, without resurfacing the entire area. Long-term maintenance cost therefore compares favourably with wetpour, which typically requires specialist contractors for repairs and presents a patchwork appearance after localised remediation.
The school requested EN1177 test documentation and a sample tile before committing. Both were provided promptly. The premises governor and insurance broker reviewed the certification and confirmed it met requirements.
The Solution
The 180m² installation covered the climbing frame area and the two adjacent running zones identified in the risk assessment as requiring impact-absorbing surfacing. Existing wetpour was removed by a groundworks contractor in the week prior to tile installation. The prepared base — compacted MOT Type 1 aggregate with a 25mm sharp sand bed — was laid to correct levels ensuring the finished tile surface would drain properly.
The tile installation took two days during October half-term, carried out by a two-person team. A small complication arose at the boundary between the tiled area and existing tarmac: the tarmac level was approximately 12mm below the finished tile surface. A tapered edge tile section was used at this boundary to create a smooth transition without additional cost.
The tiles were supplied in two colours — green and red — following consultation with school council pupils. The installation team cut tiles as needed to fit around the climbing frame legs and drainage gully positions.
The Results
In the 18 months following installation — covering three full terms and two summer periods — St. Michael's recorded zero playground injuries attributable to the surface. Insurance renewal the following academic year resulted in a 12% reduction in public liability premium, with the broker attributing this partly to removal of the outstanding floor safety risk — approximately £640 annually.
The Ofsted inspection that followed in summer term 2024 made no reference to playground safeguarding concerns. The section of the school's safeguarding documentation covering the playground surface had been updated to remove the previous risk notation and replace it with confirmation of the EN1177-certified installation.
"We had three injury reports, Ofsted aware of a documented risk, and the surface getting worse each term. We needed to sort it within budget. The tiles have been down through two winters now and there's been nothing. No injuries, no complaints from governors, no Ofsted concerns."— Claire Ramsden, Headteacher, St. Michael's C of E Primary School

Could This Work for Your School?
Rubber playground safety tiles are suitable for new installations and as a cost-effective replacement for failing wetpour surfaces. EN1177-certified tiles available in multiple thicknesses for different critical fall height requirements, and in a range of colours. Cut-to-size edge pieces allow clean integration around equipment feet, drainage points, and existing surface boundaries.
Rubber Matting Direct can provide EN1177 test documentation for review by your governing body or insurance broker. Samples available on request. The team can advise on the appropriate tile thickness for your specific equipment heights and base preparation requirements.
Frequently Asked Questions
What is the required critical fall height rating for school playground matting?
EN1177 is the key standard for playground impact-absorbing surfaces. The required CFH depends on equipment height. For equipment up to 1.5m high, a minimum CFH rating of 1.5m is required. Most quality rubber playground tiles are tested and certified to EN1177.
How long do rubber playground safety tiles last?
Quality EPDM rubber playground tiles typically last 10-15 years in outdoor use. EPDM compound is UV-stable and does not degrade significantly with weathering. Annual inspection for cracking, lifting, and joint separation is recommended.
Are rubber playground tiles suitable for use under climbing frames?
Yes, provided the tiles are rated for the critical fall height of the equipment. Thicker tiles (40mm+) provide higher CFH ratings suitable for taller equipment. Always check the EN1177 test certificate.
Can schools get government funding for playground resurfacing?
Some schools have accessed funding through the Condition Improvement Fund (CIF) administered by the ESFA. Where safeguarding concerns are documented, the case for funding priority is typically stronger.
How are rubber playground tiles installed?
Rubber playground safety tiles are typically laid on a prepared compacted aggregate base or existing hard standing. Tiles interlock at the edges and are bedded on sand or adhesive depending on the base type.
