What type of pad could be used on a wood floor to keep feet from sliding? Need to be able to clean urine drips off it also.

We just took up the carpet so that we can eventually get a lift when Mom needs one. Her feet tend to slide a little when we stand her up to transition. She often leaks a little when transitioning so whatever we get needs to be able to be cleaned and not leak through to the floor. Something thin that will give her feet some grip.
