Been there done this and it is a friggin headache. I know more about this than I wanted to know. First off the brother here makes a valid point because under the foundation is something that is hard to check but you can check all around the foundation but you will have to trench to make sure. Ground settles all around the foundation and if there is some heavy rains ( water table ) saturation of the ground will enhance water and wash out begins. As foundation is washed away water replaces it and you will get hydrostatic pressure,,,,water coming up through the foundation where it is cracked or not sealed.
