I have about an inch to make up between three newly adjusted brick piers and a 3-2x10 Beam. I know that the shim material is supposed to be non compressive and I am looking at a few metal options. It would be easier and cheaper to use wood and I have some scrap oak that would fit perfect. Are hardwoods considered non compressive if loaded along the grain? I need to make sure it's right before the building inspector stops by. Thanks for any advice .
