To keep the moisture in, you can spray concrete sealant on it.

The presence of trees near a building can also destabilise its foundation and drains.Cracks on the walls: Variations in moisture and temperature cause frequent expansion and shrinkage of the concrete, causing cracks.

You can have a company come out to do moisture readings and saving them for your records to have confirmation the area that was impacted is no longer a hazard.

There's never a great solution to that stuff, some areas are just 'low' and the moisture is always a hard issue to deal with long term as well

The laminate has moisture damage in the middle of each floor.

You might find moisture inside the basement concrete walls for instance.

Bottom line you have to get all the moisture out completely to prevent a future problem and that means ripping a lot of stuff out including getting to stuff that you cannot see.  

I installed the click TrafficMaster (floating floor) in a rental home last month, and it is holding up to moisture and pets well.The Shaw New Market 6 is a lower price ($1.13/sq ft vs Traffic Master Allure at 1.29-1.49/sq ft), but my first impression is that the Shaw might be more labor intensive.  

This is my first time posting an analysis, so please be gentle...all constructive critiques welcome of course!

I sent a restoration company out as there was moisture to baseboards and some of the drywall in the room.
