PU (Polyurethane) Courts
PU polyurethane indoor sports courts — premium specification
PU (polyurethane) is the premium indoor sports flooring system specified by FIBA, BWF, and FIVB for tournament-grade play. ChampCourts installs PU sports courts at Rs 250 - 350/sqft for basketball, badminton, volleyball, futsal, and multi-sport halls. Our PU systems are FIBA Level 1 / BWF / FIVB compliant with documented ball rebound, shock absorption, and surface friction.
PU is indoor-only — UV exposure breaks down the resin within 18-24 months. For outdoor or covered-but-exposed installations, use Silicon PU instead.
PU system construction — layer by layer
- Sub-floor: Engineered M25 PCC slab or existing power-trowel-finished concrete, primed with epoxy moisture barrier
- Elastic underlayer: 4-7 mm rubber granulate (SBR or EPDM) bonded with PU adhesive — gives shock absorption
- Self-levelling PU base coat: 1.5 - 2 mm pigmented PU resin
- Sealer + colour coat: 0.5 - 0.8 mm pigmented PU
- Line marking: 100% PU line paint, embedded
- Top coat: Matte or satin PU clear seal for stain resistance and traction
Total system thickness: 7 - 10 mm. Cure: 5-7 days for full cure before play.
PU sport applications & specifications
| Sport | System thickness | Vertical deformation | Ball rebound | Standard |
|---|---|---|---|---|
| Basketball | 8-9 mm | 1.5-2.5 mm | >= 93% | FIBA Level 1 |
| Badminton | 6-7 mm | < 4 mm | n/a (shuttle) | BWF Approved |
| Volleyball | 7-8 mm | 2-3 mm | >= 90% | FIVB Level 1 |
| Futsal | 9-10 mm | 2-3 mm | >= 50% (low) | FIFA Quality |
| Multi-sport | 7-8 mm | 2 mm | varies | Multi-federation |
Why choose PU over acrylic, vinyl, or hardwood
- vs Acrylic: PU has 5-10x more shock absorption — protects joints during repeated jumping (basketball, volleyball). Acrylic is harder, faster ball pace, outdoor-rated.
- vs Vinyl roll: PU is seamless (no joints), point-elastic (deforms only where load is applied), and customisable in colour. Vinyl is faster to install and cheaper.
- vs Hardwood maple: PU is 50-70% cheaper than premium hardwood, doesn’t need climate control, easier to maintain, and supports more sports. Hardwood is the FIBA Pro / NBA gold standard for basketball only.

FAQ
What is the cost of a PU sports court in India?
Rs 250-350/sqft surface-only on existing slab. A full basketball court runs Rs 11-16 lakh. A 4-court badminton hall: Rs 17-24 lakh. Add Rs 90/sqft if civil sub-floor is required.
Can PU be installed outdoors?
No — UV breaks down PU resin within 18-24 months. For outdoor use, choose acrylic or Silicon PU.
PU vs vinyl roll — which is better?
PU is seamless, more durable, supports more sports, and customisable. Vinyl is faster to install (10 days vs 18 days) and cheaper (Rs 80-150 vs Rs 250-350). Choose PU for premium / long-term institutional. Vinyl for quick BWF-compliant badminton installs.
How thick should PU be?
6-7 mm for badminton (light play), 8-9 mm for basketball/volleyball (heavy jumping), 9-10 mm for futsal (ball control + impact).
How long does PU installation take?
12-18 days on a prepared slab. Add 21 days for civil if PCC base is also being built.
What is the lifespan of PU flooring?
10-15 years with normal indoor use and recommended maintenance. Top coat re-application at year 5-7 extends life to 15-20 years.
PU floor cleaning & care products
Use only PU-rated cleaners. Avoid common floor-cleaning mistakes:
- Yes: Neutral pH (6.5-7.5) cleaners; microfibre mops; auto-scrubber with soft pad; PU-specific products from manufacturer
- No: High-pH detergents (damage finish); abrasive scrub pads (scratch top-seal); vinegar (acidic); steam mops (heat damages adhesive); excessive water (penetrates joint at edges over time)
- Spill response: Wipe immediately; sport drinks and sweat are slightly acidic and will dull finish if left overnight
- Heavy soil: Use auto-scrubber with PU-cleaner solution; do not use rotary buffers without appropriate pad
PU layer thickness vs sport demands
Each indoor sport has specific demands on PU system thickness:
- Badminton: 6-7 mm — emphasises shuttle bounce, smooth surface, low foot fatigue
- Basketball: 8-9 mm — FIBA ball rebound spec, jump landing protection
- Volleyball: 7-8 mm — knee protection from repeated jumps; spike-landing absorption
- Futsal: 9-10 mm — ball control + low-bounce ball + sliding tolerance
- Multi-sport (basketball priority): 8 mm compromise — works for basketball, volleyball, and badminton overlay
- Gym / functional: 4-5 mm self-levelling — light recreational use
PU colours and aesthetic options
Indoor PU floors are highly customisable visually — institutions use this to project identity:
- Solid block colour with sport lines: Most common; choose one primary court colour + sport-specific line colours
- Two-tone court + run-off: Inner court one colour (e.g., royal blue) with lighter run-off (light grey)
- Custom logos and graphics: Centre-court school crest, corporate logo, federation emblem
- Sponsor zones: Designated areas for sponsor branding on indoor competitive venues
- Pattern blending: Gradient effects, two-colour speckle, designer mixes
PU acoustic considerations
Indoor PU halls are acoustically alive — ball thumps, shoe squeaks, and shouting all carry. Acoustic treatment matters:
- Ceiling acoustic baffles (fabric-wrapped fibreglass panels) at 8-12% of floor area
- Wall absorbers behind end-walls (basketball baselines, badminton end-line zones)
- Soft seating instead of metal bleachers where possible
- Avoid hard parallel walls (creates flutter echo)
PU system types — choosing the right configuration
| System | Thickness | Force reduction | Use case | Cost (Rs/sqft) |
|---|---|---|---|---|
| Area elastic (single layer) | 4-5 mm | 10-20% | Light recreational | Rs 250-275 |
| Point elastic (dual layer) | 7-8 mm | 25-35% | Club / school | Rs 280-320 |
| Combi-elastic (sprung + PU) | 9-12 mm | 35-50% | Premium FIBA / FIVB | Rs 320-380 |
| Self-levelling PU (commercial) | 3-4 mm | 5-10% | Gyms, light play | Rs 180-220 |
Sub-floor preparation — critical for PU success
PU bonds chemically to the concrete sub-floor. Any failure in sub-floor preparation guarantees long-term system failure. Our pre-install protocol:
- Moisture test: Calcium chloride or capacitance meter, < 5% MC required
- Surface profile: CSP 2-3 (concrete surface profile), achieved by grinding or shotblasting
- Cracks: > 0.3 mm filled with epoxy crack-fill; > 2 mm structural movement joints respected (PU bridges with movement strip)
- Level tolerance: <= 4 mm/2 m straightedge; greater deviation requires self-levelling underlayment
- Cleanliness: Vacuumed, then primed; no oil, no curing compounds, no dust
- Ambient conditions: Maintained at 15-30 degree C, 40-65% RH during install and cure
Multi-sport line marking on PU
PU systems support up to 6 sport line systems on one surface. Line paint is PU-based (not acrylic) to ensure chemical bond with the floor — applied between final colour coat and top seal so lines are embedded, not surface-painted. Standard colour system:
- White — primary sport (basketball)
- Yellow — badminton
- Blue — volleyball or pickleball
- Red — futsal or kabaddi
- Green — auxiliary sport (rare)
Line widths follow federation specs: basketball 5 cm, badminton 4 cm, volleyball 5 cm, futsal 8 cm.
Case study — Bangalore corporate sports hall, 4-court badminton + basketball overlay
A multinational tech company commissioned a 36 x 18 m indoor PU sports hall on their Whitefield campus in 2025. The hall hosts 4 badminton courts (cross-orientation) + 1 basketball half-court overlay + 1 yoga zone.
- Sub-floor: existing power-trowel concrete, ground and primed
- System: 8 mm point-elastic PU (badminton-optimised, basketball-compliant)
- Colours: Royal blue primary courts, light blue run-off, multi-line marking white/yellow
- Lighting: 36 x 100W LED side-mounted, UGR 16, 800 lux uniform
- HVAC: 4 x 5-ton VRF system maintaining 22-26 degree C and 45-55% RH
- Total surface + line marking cost: Rs 28.5 lakh (excluding HVAC and lighting which the GC bid separately)
- Outcome: Hall used 12+ hours daily; corporate employees report it’s the best-loved campus amenity
PU maintenance protocol
- Daily: Dust mop with microfibre; wipe spills immediately with neutral pH cleaner
- Weekly: Damp mop with PU-rated cleaner (no abrasives, no high-pH)
- Monthly: Inspect line paint and top-seal; touch up worn areas
- Quarterly: Deep clean and buff with auto-scrubber
- Annual: Inspect adhesive bond at edges, check for any lifting or bubbling
- Year 5-7: Re-coat top seal (1-2 mm fresh PU layer) — extends life by 8-10 years
- Year 12-15: Full re-coat (resand wear layer, fresh colour + top seal)
Choosing PU thickness — sport-specific guide
The right system thickness depends entirely on the dominant sport and intensity:
- Yoga / aerobics / light recreation: 3-4 mm self-levelling PU
- Badminton (single-sport): 5-7 mm point-elastic — emphasises ball-friendly bounce
- Volleyball-dominant: 7-8 mm point-elastic — protects against jumping impact
- Basketball-dominant: 8-9 mm — FIBA ball rebound spec
- Futsal: 9-10 mm combi-elastic — FIFA Quality control + low-bounce ball
- Multi-sport priority basketball: 7-8 mm point-elastic compromise
