So which one should I choose for my site?→ How to choose suspended flooring vs. silicon PU · Cost comparison
| Dimension | Suspended interlocking flooring | Silicone PU court |
|---|---|---|
| Installation Period | 2–3 days | 15–20 days (including layer-by-layer curing) |
| Base requirements | Concrete/asphalt is sufficient, with large tolerance | Leveling + base strength meeting standard required |
| Weather Dependence | Low (no curing period, can be installed at 5–40℃) | High (cannot be installed in rain/low temperatures; each layer needs to cure) |
| Drainage | Elevated base + surface drainage channels | Surface runoff (depends on slope grading) |
| Recovery after rain | 5–15 minutes | 1–2 hours |
| Ball rebound | ≥ 95% (core models) | 95–100% |
| Impact absorption | Core models ≥ 53% | 30–50% |
| Overall surface cohesion | Has seams (larger tiles reduce the seam feel) | Seamless Monolithic Surface |
| Repair method | Localized single-tile replacement | Redo the entire surface |
| Weathering and Fading | Anti-UV formula, slight aging within 8 years | Whitening and hardening within 5–8 years |
| Service life | 8–10 years (8-year warranty) | 5–8 years |
| Typical cost | CNY 120–280/m² | CNY 180–260/m² |
Depends on the sport and venue conditions. The advantage of silicone PU is its seamless, monolithic underfoot feel; the advantages of suspended flooring are drainage, build time, localized repairability, and basketball/3x3 (3-on-3 basketball scenario). Both have professional application scenarios,The key lies in the base conditions, drainage needs and maintenance approach, see details in Anti-Slip and impact absorption。
Not absolute. Silicon PU is about 180–260 RMB/㎡ and suspended flooring is about 120–280 RMB/㎡, with overlapping ranges. High-end suspended flooring models can also be higher than silicon PU; once base leveling is included, the installed price of silicon PU is also not low.Price comparison should be calculated to the completed price and 8–10 year full-lifecycle cost, don't just compare unit price.
Seamlessness is a feature of silicone PU, but it turns repairs into "redoing the entire surface"; the seams of suspended flooring buy you drainage, release of thermal expansion and contraction, and local replaceability.What truly affects the experience is whether the base is stable and the surface is level, not whether there are seams.
Campus basketball court: In most cases, suspended flooring is the safer choice — good drainage, usable right after rain, installation that doesn't disrupt teaching, and it meets GB 36246-2018; Silicon PU can be considered when the base is brand new, the budget is ample, and a soft, springy, unified feel is desired.
Community multi-purpose court: The top choice for suspended flooring — multi-project compatibility + easy maintenance + long lifespan; see Community multi-purpose court feature。
Renovation of old courts: When the original silica PU/acrylic surface layer is level, suspended flooring can be laid directly over it — no removal needed, minimal dust, and a short construction period.
Product Selection & Cost: first examine the base and drainage conditions, then calculate the completed price and full lifecycle cost; refer to Modular sports flooring price range guide。
Their cost ranges are close. Silicon PU is about ¥180–260/㎡, and interlocking modular flooring is about ¥120–280/㎡, with the final unit price subject to venue area, model, base conditions, and contract. Because silicon PU requires base leveling and multiple application passes, its installed price for low-budget projects is often not low.
Yes. When the original silicone PU surface is flat and free of large-area bulging or delamination, suspended assembly flooring can be installed directly on top of it without removing the old surface, giving a short refurbishment time and low dust. Where the base has serious hollowing, do localized repairs first.
Both are common for campus venues. For venues that need fast drainage, ready to use after rain, installation that doesn't disrupt teaching, and single-panel replacement, prioritize suspended interlocking flooring and verify GB 36246-2018 testing; for those seeking a seamless, unified underfoot feel with good base conditions and ample budget, silicon PU can be evaluated.
Silicone PU is an elastic surface layer cast on-site, dependent on the flatness and strength of the underlying concrete/asphalt base. Base cracking, hollowing, or inadequate slope grading will directly show through to the surface, and later repairs require redoing the whole section; suspended flooring relies on its raised base and locks, giving greater tolerance for the base.
Silicone PU outdoors typically lasts 5–8 years; after prolonged sun exposure the surface whitens and hardens. Suspended interlocking flooring's anti-UV formula corresponds to over 8 years outdoors, with an 8-year contractual warranty, and life can be extended through partial replacement. Actual results depend on the usage environment and maintenance.
