Drilled Displacement Piles
Drilled Displacement Piles
(OP)
Anyone out there very familiar with these types of piles?
Whats the maximum capacity of a typical pile? How large a diameter pile is typical? I've got a situation where original piles were 50 ton, and I need 70 ton. No piles installed yet, but i'm hoping I can increase the diameter of the pile to get the 70 tons.

And if the allowable load is controlled by the soil or rock then how can they claim 250 tons?

RE: Drilled Displacement Piles
On cooling tower job mentioned, (based on geotechnical recommendations) I had specified point bearing, steel HP 12x53 with nominal 40 ton capacity. The Contractor bid the traditionally driven HP, and offered an unsolicited proposal for a one-for-one replacement of the HP with DeWaal piles. Since this Contractor was the low bidder on the specified HP approach, we pursued the unsolicited proposal and negotiated a turn-key design for the DeWaal pile (at a substanial savings). Here is a link to the engineering firm that did the design for that job

I have reason to believe that they have substantial experience designing DeWaal pile projects. Perhaps they can answer your question.
