High Moisture Levels 1 year after slab poured, residential home
My husband and I purchased a brand new home (slab) in Ga

Slab poured January 10 2012
engineered hardwoods installed April 14 2012
Dark spots/orange peel texture begins to appear in July 2012

Mold present under floor. 4 calcium chloride tests with results of 7 (carpeted room) 16, 16 and 17 were completed December 2012

The builder stated the timing of construction was to blame. Our floors were removed February 22 2013 and small surface cracks were present which seems to indicate a cured slab.

Wagoner RH metered were placed and the first set of readings taken 40 days after the floor was removed and the slab had been exposed ... readings were upper 80s.

One core was taken from our slab in February showing a vapor barrier but uneven bottom of slab. The core was tested and showed strong and normal composition. Water tables were done outside and normal, cameras were run through pipes and no leaks.

Any thoughts on what is going on or what to do? Builder is suggesting re-install once acceptable levels are achieved. We are currently re-doing calcium chloride tests.

Thank you in advance.
