Drilling for Caissons?

[fensoncont.]

Hey everyone,

I was wondering what kind of production soilmec drills can get drilled 24-36" shafts in silty clay, clay. What about when you get into sandstone or claystone? Still use a soilmec drill? How long does that take?

Thanks

A driller might be able to answer that type of question if he had all the information. How deep and boring log with blow counts.
