PWF lumber vs treated

jeff_40 | Posted in General Discussion on November 19, 2020 06:16pm

Recently we bought a home with a block foundation. One of the basement walls was bowed in about 1-2”. We hired a structural engineer who suggested building a pwf wall with the base anchored into the footing and the top bolted to the floor joist. Well stupid me just picked up and cut about 400$ worth of pressure treated lumber thinking it was the same as pwf. My question is will the pressure treated lumber be alright for the job as long as i seal all my cut ends?
I should also add the exterior of the wall has been waterproofed and damp proofed.

    What is the original foundation wall built of? Stone/ block/concrete ? If it's bowed are there cracks gaps?
    You say that the original is waterproof , so is the new wood wall inside a dry basement? If that's the case I wouldn't worry about your choice of pressure treated wood. If there is wetness or dampness different story..

    The original foundation is concrete. Yes there are horizontal and step cracks. Last year we had a contractor excavate the perimeter, install new weeping tile, fill in all the cracks with hydraulic cement as well as place a bead where the block meets the foundation. Then he coated the wall in tar and wrapped the house delta ms dimple membrane.
