I am looking to install vinyl flooring on my basement (ground level). I will be removing the existing tiles. On 2 of the walls (the ones that face the exterior) I have this mini step along the walls (see images below). It looks like continuous wall footing basement or maybe the drainage goes beneath that.
Can anyone confirm what that is and the best way to deal with it when installing new floor? It's going to be a challenge to install vinyl with that.
Any help is appreciated!
