Yes, and at first glance it might seem like a time and cost saving answer. However the reality is, it usually leads to problems down the road, especially in basements or areas with high humidity or a high water table.

Concrete is porous and over time moisture can work its way up into your flooring. This could cause mold and mildew, permanent damage to your flooring. 

Common Risks of Installing Flooring Directly on Concrete

• Moisture damage: Swelling, warping, or buckling of laminate, engineered wood, or hardwood.
• Mold & mildew: Trapped moisture under flooring creates an ideal environment for growth.
• Cold and hard underfoot: Concrete offers no insulation or cushioning.
• No vapor protection: Concrete slabs can emit vapor for years, even if they appear dry.

Why It’s Not Recommended

Most flooring manufacturers require a moisture barrier or underlayment as part of their installation guidelines. Skipping this step can void warranties and significantly shorten the lifespan of your flooring.
