Hi, I need to replace my existing tongue and groove chipboard floor, due to the current one being warped throughout the flat and squeaking due to loose studs underneath. After removing it, the studs (32x50mm) were not secured to the rather uneven block and beam floor, nor levelled (im guessing resulting in the uneven and noisy floor previously). I now want to level and secure the studs ready for the new flooring. Is it acceptable for me to be screwing these into a block and beam floor (ensuring I only screw into the blocks). I was intending to reuse the 32x50mm studs and secure them with 6x80mm hammer in fixings + packers underneath to level. Do I risk cracking the blocks with this approach, or would I be better off bonding the studs? Many thanks!
