Just looked at the photos. Most of the slab on grade foundations we do are 8 inches above adjacent grade and that grade slopes another 6 inches within the next 10 feet away from the foundation. To the end that runoff flows away from and around the foundation. More important if the soil has high clay content.
Your right. We had a lot of rain and it ran off into the beams. Thier going to dig it back out and raise it again when we get some dry weather.
