Check the slab first
Review stability, large cracks, movement, high or low areas, old coatings, contamination and any drainage or ponding problems before the court surface is ordered.

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.

Review stability, large cracks, movement, high or low areas, old coatings, contamination and any drainage or ponding problems before the court surface is ordered.
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.
Expansion gaps, edge details and preparation should follow the selected tile system and actual court layout.
