These types of flooring include hardboard particleboard osb and plywood. Tile and stone flooring can be installed directly over concrete but most other flooring materials require some kind of underlayment and or a moisture barrier laid over the concrete. If your subfloor doesn t pass the flex test either because it s a bathroom floor and has sustained moisture damage or it s the wrong material you can and should replace the damaged section. There are also engineered subfloor panels designed for covering concrete slabs in.

Certain types of subflooring known as resilient flooring are good for rooms that will not be exposed to a lot of moisture like living rooms kitchens and bedrooms. This adds to the cost of the project but it s better to pay a little extra during installation than it is to tear up a failing tile floor that has.

Because of issues of moisture movement and adhesion ceramic tile will work well with certain types of subfloor underlayment systems and can go dramatically wrong with other subfloor materials.

Traditionally exterior grade plywood has been the subfloor material of choice for many bathroom flooring projects. The floor must also handle the weight of the tub shower tiles and other fixtures.
