Anyone have experience with screw / helical piles?
Wife is asking about extending the cottage rearward for more living space and one consideration instead of excavating is that type of floor support.
Anyone use them before? How do you insulate the floor? We don’t need a bigger basement so I’d be ok with just building an addition for some more space while keeping the basement as is.
Done properly, they can work well. Proper screw piles measure torque during install. There is a known relationship between torque and bearing capacity. Talk to the structural engineer that has to sign off and local building department to see how they feel. Ultimately, what they accept matters more than what works.

They’re not DIY. I’ve used them a couple of times, the diy ones are unstable , the machine torqued piles are great… except for cost, about $1000 a piece.
Just use concrete filled sono tubes, inexpensive, easy DIY.
