What is the best way to compact wet clay to 95% mod that is being dumped on a site that has the water table just a few feet below the surface. Not to mention that this is the wettest time of year in louisiana. I'm building a house pad and the homeowner needs to pour the slab in the beginning of january. The lot is flat with pipelines running along the only two sides with a ditch and the the pipeline company won't let me cut ditches across there pipeline to help with drainage. I'm trying to not use lime because I don't have a stabilizer. I'm looking for tricks of the trade that I may not know about. I have a dozer, excavator,tractor with discs and dump trucks. I'm trying to purchase a padfoot compactor.
