Long story short I constructed a shed foundation on uneven ground with piers concreted into the ground. This however turned out to be 2” out of square and is a slight rhombus shape - and to correct this I need to gain 2” in opposite corners.
I attempted this with a sort of sistered joint, secured with two coach bolts and two screws at regular intervals. This went okay, however I’m concerned about the load it will be able to take as it will be bearing one of the shed walls. The sistered joint is not sitting on the pier post like the 2x 2x4 it’s bolted to.
If this is not substantial enough, then my other option is to source longer timber length to achieve the same thing.
