I inspected a property and noticed a 1” gap between grade and the foundation of the house. The gap runs around the whole property perimeter. There is moss growth on the lawn and a huge tree in front of the house. My first thought was some form of a leak underground is causing the soil to move away from the house and moss to grow. I checked the moister in the basement foundation and it was normal compared to other houses in the area. I know I don’t have to find what the cause is, but I’m curious to know what it could be as this the first time I see something of that sort.
Dehydration of the soils caused during transpiration by the HUGE trees nearby. If you add low rain conditions it can aggravate the situation. One name for this is “Drying Edge Effect”.
This is in michigan, so drought is never a problem. I noticed the house to the right has the same problem, while the house to left doesn’t. There is a fire hydrant between this house and the house to the right. I thought maybe there is a breakage in the ground but Where is the water going if that’s the case?
