What is the load bearing capacity of a 12″ Pearson pile?
The wall thickness of our 10″ diameter pile is .31″ and the 12″ and 14″ are both .375″. The ultimate load capacities vary dependent upon cantilever length, but, generally speaking, the 10″ is used in 5 ton to 26 ton applications, the 12″ is used up to 30 tons and the 14″ up to 40 tons. The load capacity at compressive yield for a short length 10″ composite pile can be as high as 40 tons, but I would be hard pressed to say that is a reasonable application.
