Re: Geopier(R) / Rammed Aggregate Pier(R)

Yeah, I'm not concerned about their overall effectiveness. I wanted to find 
 out if anyone had experience with them, as a prelude to asking a further 

In my case they're being proposed for a site that is extensively 
contaminated with crude oil residue (the crude was originally put there 
nearly a century ago and the volatiles have since evaporated out leaving a 
high-viscosity tarry substance that nevertheless tends to migrate under 

Since the Geopiers are constructed by ramming to create a pressure bulb in 
the surrounding soil I wonder what the ultimate effect will be in the 
presence of the crude oil tar.
