Can Sports Tiles Go Over Concrete?
Yes—modular sports tiles are commonly considered over concrete, provided the slab is a suitable supporting base. The fact that the tiles interlock does not remove the need to inspect the concrete first.
Planning guidance — final supplied configuration remains project-specific.
Drainage still matters
Open modular tiles can let water pass through the playing layer, but the concrete below still needs a practical route for water to leave the site.
Final installation is system-specific
Expansion gaps, edge details and preparation should follow the selected tile system and actual court layout.
