Pile to Base Slab Connection
Pile to Base Slab Connection
(OP)
Simple question. (Or maybe not) Is it acceptable to have an auger cast pile that is not "sunk" into the base slab but merely connected to the base slab via hooked rebar? Do any of the codes prohibit a flush connection when both components are cast in place?

I used to have a note requiring the contractor to place concrete in the piers to a level 2" higher than required, and then later chip off the top 2" to remove this "bad concrete".
For an auger cast pile, the top strata of concrete/grout can be loose, higher in water content (due to rising water) and may be damaged by subsequent excavations around the pile top. Sinking this in a cap of concrete for 4 to 6 inches simply helps confine this concrete and minimizes crushing and settlement.

Thanks for the response.
