When installing a subfloor over concrete, it is important to first ensure that the concrete surface is clean, dry, and level. Use a vapor barrier to prevent moisture from seeping into the subfloor. Install sleepers or furring strips to create a gap between the concrete and the subfloor for air circulation. Use adhesive or screws to secure the subfloor to the sleepers. Finally, consider using a moisture-resistant subfloor material to prevent mold and mildew growth.
