Angry Moisture

I want to install vinyl in my car port that I have made into a play room. I put in some tile vinyl and now it is comeing up and there is water under the tile. I installed the tire abount one year ago. I was told I should have done a moisture test before installing the tile. My question is would a high amount of moisture caused any problems before it showed up at one year. I think there is another problem that might cause the water to surface.

It's possible something else is going on, but then again, possibly not. It's winter for most of us and my area is very wet this time of year. Concrete is actually quite absorbent and will wick ground water right up through it. Slabs below grade routinely have moisture issues that must be dealt with before installing any impervious floor covering such as sheet vinyl or vinyl tiles. The vinyl tiles aren't quite as bad due to the seams every twelve inches allowing a little of the moisture to escape so it sometimes takes a bit longer for problems to develop, but develop they will if you have a moisture problem and it wasn't treated properly.

What you are experiencing may be hydrostatic pressure usually caused by a fluctuating water table and/or lack of proper grading and land drainage/excavation practices.

When a slab is on-grade or below grade, with no separation/space between the ground and the concrete, as Smokey stated, it acts as a sponge and any moisture is drawn towards the concrete slab.

There are a few things you can do to ease it up a bit, like soil grading, installation of a trench system with a sump pump, penetrating sealers and coatings meant to prevent hydrostatic pressure up to a certain psi.

It also could be water from somewhere else.

How certain are you that it is coming through the slab and not from a wall/retaining-wall ?

Water is a mysterious beast and will almost always find a way.

Of course we are all just guessing, and without knowing the exact cause any remedies you my try to apply might be for naught.

I would suggest getting a concrete or basement waterproofing specialist or inspector in to have a look at it to determine exact cause and offer advice for rectifying the problem. Then you will know for sure.
