WE have red clay keep oozing from underneath the commode on the floor. Our house is built on a slab and we keep wiping red clay that oozes from under the commode in the shape of a hill shape as if it was an ant hill but no ants. We have been in this house for about 7 years and this has been going on now for the last 6-9 months. IS this a plumbing issue or problems with the slab?

Could be both. Water is leaking from the toilet during a flush and softens the dirt letting the floor settle and it squishes the dirt out. I would suspect a bad wax ring or possibly a cracked flange or drain but you need to pull the toilet. Could be a floor crack in conjunction with above noted conditions.
