Piles using water jetting - Sandy soil

[PT999]

In designing water jetted piles, is there a design procedure different from standard driven piles?


When these piles are installed, since there are no blow counts, how do you determine that you have reached load capacity?

Any books on this?

After jetting, say at least 24 hours after jetting is completed, a few blows with a traditional pile hammer can be used to confirm bearing value.
No books that I am aware of.

Sure, but the jetting contractor is going to bring a traditional hammer

Did you mean "is NOT going to bring a traditional hammer"?

You could call GRL and ask them to determine the pile capacity by dynamic (PDA) testing.

Yes, "not going"
