Q & A

Answers to commonly asked questions from the experts on Thumbtack.

What is the best waterproof flooring for a basement?

There are several great options for waterproof basement flooring. For example, epoxy floors are waterproof but are thicker and sturdier than paint. Make sure the concrete substrate has been prepared for application.

Tile is a designer’s dream, giving you a moisture-resistant surface that’s infinitely customizable. Rubber sheets or tiles are also good waterproof options, particularly for playrooms, workout areas or laundry rooms.

Vinyl tiles and planks imitate wood or other materials very convincingly, provide moisture resistance and last a long time. And sheet vinyl is affordable and a great waterproofing solution for those in need of quick fixes.
