silt in drain tile

[John Dirks Jr]

This is the second house in the same neighborhood that I found this condition. The area is known for a high water table. What exactly would the make up of this silt be and why does it rise up so easily?

That's disgusting! Usually, a properly installed fabric as a part of the perimeter drain should prevent that. Apparently, it isn't properly installed - assuming this is a relatively new home.

I had been told that it was very very fine particulate from a high clay content with combination of high water table. I don't know if that's eally it or not. 2001 construction.

You could have a house built on an aquifer. Whatever it is, the drain tile is toast.

The footing/foundation wall may be getting undermined. No filter-fabric was used? Silt in a sump pit is bad news.. had to come from somewhere near the drain... Also, could be that 'iron bacteria' issue...
