New treated timber piles were drive

New treated timber piles were drive

(OP)
New treated timber piles were driven to a depth of about 40 ft with a refusal criteria of 4 blows/in. (20000 ib-ft hammer). Pile diameter=12" and the soil is expected to be sitly sand materials. The piles will be embedded 9" into pile caps.

I am concerned with the appearance of cracks on the pile butts as shown in the attachment. The cracks seem to be of intrinsic nature and not developed by driving. I would appreciate feedback on the appearance of the piles and if such appearance would be a common problem in timber piles.

No attachment.

RE: New treated timber piles were drive

I don't know much about driven wooden piles but I deal with a lot of timber strucures and those cracks look like end checking as a result of shrinkage, not stress from driving.
