I dont know for sure to say move the sand and put a 6 mil poly down and the sand back on top. Or put the 6 mil poly on top of the sand. On top or under, Over lap it 2 ft tape all seams up the wall about a ft. close all outside vents never open them again.Insulation on the walls. Check all gutter on the home make sure all spouts run away from the home. GO to and read it
