Drywall over Drywall resistance to cracks
Have a house that has foundation movement. The engineers say the movement is within tolerances and the foundation is not failing. As a result of the movement cracks in some walls appeared. About 3 years ago a repair person said the cracks were at drywall joints that had not properly been taped and muddied (the house is about 40 years old). So he taped with paper tape and muddied. The weather has been really dry and the foundation has moved and the cracks have reappeared. I have two questions - 1. If the joints are redone using mesh instead of paper tape, will that add significant strength or flexibility so as to prevent future cracks? 2. If we drywall over the old drywall with the joints in different place from the original, will that add significant strength or flexibility so as to prevent future cracks? Then I guess number 3. What would you do to prevent future cracks? Thanks in advance for your help.
