Hi,
I'm currently looking for somewhere around South East Iowa that would sell straight clay to patch up a small hole in my pond. Any idea on anywhere I could get this around the Iowa City/Cedar Rapids/Davenport Area? I've pretty much made up my mind on using straight clay instead of sodium bentonite but if anyone even has suggestions on where to get that instead of clay, I'd still be happy to hear it. I'm open for a company delivering it or else picking it up.

I've honestly haven't had much luck looking on the internet or through the quarries websites around here. Maybe I'm looking in the wrong place
