What Is Modular Interlocking Sports Flooring?

Modular interlocking sports flooring is a PP lock-together court system for basketball, kindergartens and multi-sport courts. Structure, materials, scenarios and buying tips.

Dali, Yunnan ANK5 court (2023) — 50×50cm large format

Quick answer: Modular interlocking sports flooring is a court system based on modified PP (polypropylene). Each tile (typically 25×25cm or 50×50cm) locks to its neighbors via side latches — no full-surface glue — with a raised base for drainage, cushioning and thermal expansion. It's widely used for school basketball courts, community multi-sport courts, kindergartens and indoor/outdoor courts.

How It Works

Lock assembly: tiles connect via 8- or 16-point side locks, no full glue
Raised base: each tile floats ~1.2-1.85cm above the hard base on support columns
Expansion gaps: 0.2-0.5mm micro-gaps absorb PP thermal movement, preventing summer buckling
Drainage: raised base + surface channels drain rain in 5-15 minutes

How to Choose

For schools/government, first verify hazard-substance test reports (China's GB 36246-2018). For outdoor courts, balance slip and shock absorption. For 3x3 events, use FIBA-certified models. See the full product matrix.

FAQ

Does it need glue?

Usually no full-surface glue — tiles lock together. Edges and special areas may get local reinforcement.

How soon usable after rain?

Quality tiles with raised base + surface channels drain in 5-15 minutes after rain stops.

Will it buckle in summer heat?

Quality products reserve 0.2-0.5mm micro-gaps for thermal movement; install also leaves 2-3cm perimeter gaps. Improper tight installation buckles above 40°C.

Same as a running track?

No — modular flooring is rigid court tiles; running tracks are cast PU/EPDM elastic systems with different sports and tests.

Can I lay over an old court?

Yes if the base is flat (≤5mm/3m), cracks <5mm, no standing water. No need to fully demolish.
