I am in charge of repairing a deck that has sunk about two inches and is now uneven with the stairs. I dig and discovered that there is concrete aroumd the base of the post nearest the sinkage. I can't jack it up higher and resecure it due to the existing concrete makes it too heavy.
My question, Is it smart to cut the 6x6 post (2ft below the ground) with a sawzall, (deck supported by wooden 4x4 on car Jack's) jack the deck up and pour new concrete on top of the old concrete and let it all dry before releasing the jacked up deck. There would now be about 12" of the main post still in concrete directly on top of the old concrete. The deck is small and only 8ft by 12ft, would it still be secure enough after cutting the post?
