EPDM Play Area for a Preschool Campus

Four EPDM rubber zones, each a different primary colour — chosen after the school let a class of four-year-olds vote by pressing painted handprints on paper.

THE CHALLENGE

The principal had seen too many scraped knees. The existing play area was compacted red earth with a few patches of concrete thrown in — barely functional, and completely wrong for children still learning how to run. Every monsoon, it turned to slick mud. Every dry month, it cracked and buckled. Falls were not occasional. They were daily. The principal knew this had to change, and she came to ChampCourts with a specific ask.

"I don't want another slab of grey concrete," she said at the first site visit. "I want something that looks like it belongs in a children's world." Safety was the first requirement — the surface had to meet fall height certification for the climbing equipment already on site. Non-toxic materials were non-negotiable; these were three- and four-year-olds who would touch, sit on, and occasionally taste whatever was laid down. No trip edges anywhere. Rounded borders with no sharp transitions at the perimeter. She had thought it through carefully.

THE SOLUTION

EPDM rubber was the clear choice. Unlike PP tiles or acrylic — both better suited to sports courts — EPDM is the global standard for playground and early childhood surfaces. It is poured and trowelled in place, creating a seamless bond with the substrate. No trip edges, no joint gaps. The rubber compound is REACH-compliant — free of heavy metals, phthalates, and PAHs. Once cured, it handles Jaipur's extreme temperature swings without issue. We are talking 47°C in peak summer down to near-zero in January. It does not crack. It does not go brittle.

We specified a two-layer EPDM system: a 12mm SBR base layer for shock absorption, topped with a 3mm EPDM wear layer in each zone colour. The combined 15mm thickness gives a Critical Fall Height (CFH) rating suitable for equipment up to 1.5 metres — comfortably covering the slide and climbing frame already on site. At the perimeter, we formed a gradual bevel taper from 15mm depth down to flush with the surrounding paving. No raised edge. No trip hazard. Anywhere.

THE BUILD

Work started on a Monday, timed to a two-week school holiday. The existing surface needed more work than we had anticipated. Three areas had subsurface voids — if we had left them, the EPDM would have cracked within months. The crew spent the first two days cutting out and re-casting those sections with M20 grade concrete, then grinding the entire slab to a consistent tolerance of ±3mm across all 2,400 square feet. Only once the substrate was right did the rubber work begin.

Day 2 — grinding the existing concrete to ±3mm flatness before any rubber work. Not glamorous, but this is what makes the surface last.

Day 4 — the 12mm SBR base layer being hand-trowelled. The crew worked zone by zone to keep the wet edge continuous and avoid seam lines.

Day 7 — colour zones taking shape. Masking tape and screed boards defined each boundary before the colour was poured. Millimetre-level accuracy.

Day 10 — handover morning. Four zones, crisp boundaries, ruler-sharp edges. Looks like a patchwork quilt from above.

The colour zoning was the most visible design decision, but it was also practical. Each zone mapped to a play activity: Red anchored the climbing structure, Yellow was open running space, Blue surrounded the sand pit, and Green defined the quiet activity corner. No physical dividers between zones — just colour — so children could move freely without any trip hazard between areas. At each colour transition, we used the same two-part polyurethane binder as the rest of the field. The joint is as strong as everywhere else.

The bevelled perimeter edge was hand-formed on Day 9. We use a purpose-made screed guide to create a consistent 45-degree taper from full 15mm depth down to flush with the surrounding paving. It takes extra time. We do it on every children's surface because a hard edge at the perimeter is an injury waiting to happen. The result is a surface with no raised edge anywhere on its boundary — just a gentle slope that is impossible to trip on and easy to clean.

THE RESULT

Six months after handover, the school has recorded zero injuries from playground falls. That is a complete turnaround from the two academic years before. The admissions coordinator told us something we had not expected: when prospective parents visit the campus, the playground surface is consistently what they photograph and bring up in their follow-up conversations. Three families have explicitly said the play area was the deciding factor in choosing this school over nearby options.

The school's annual brochure features the EPDM play area on the inside front cover — a full-bleed photograph of children running between the Yellow and Blue zones. The principal asked us for a copy of the installation specification sheet to include in the school's safety policy documentation. "Parents should know exactly what is under their children's feet," she said. We sent it the same afternoon.

The surface has shown no signs of delamination, colour fade, or joint separation. Rajasthan summers are brutal — sustained weeks above 44°C will degrade lesser materials. But EPDM's UV stability means the colours are still saturated. Maintenance has been minimal: a monthly rinse with mild detergent and a quarterly check of the bevel edge. The substrate preparation on Days 1 and 2 — cutting out voids and grinding concrete, the work nobody photographs — is what is paying off now. A surface is only as good as what it sits on.
