We had a difficult job. We had a wet basement and American Eagle dug around the inside perimeter of the house down to the footers. We found out we had two slabs which was very individual. We are on the water and by the time they dug all the way down there was a lot of water and I thought there was always going to be water. But their system worked great using a superior product. We have a dry basement and we were not charged more for the extra work. Would totally recommend them!
