water in garage?
My garage is about 50+ years old, it is detached from the house. The inside has no insulation or drywall, the celing is open to the rafters and ceiling joists as well. The problem I have is when it rains hard for a long time, water actually comes up though the concrete, not puddling, but the whole slab becomes moist to the touch. And I do have adequate drainage, the land slopes away from the garage on all 4 sides and the gutters are piped out to the street.
Now I have thought about doing some kind of sealer on the concrete so this does not happen so I am not sure if this is a good fix or not.
Also becasue of this I have a serious problem with condensation, I use the garage as a work shop and I am noticing my tools are becoming rusty very fast, I am sure this is because the moisture can not escape once it comes though the slab. Now my roof does not have any venting at all, would adding a few of those cheap plastic roof vents help this problem? If so how many do I add? The garage is 10'x24' and with a 8' plate height and again the rafters are open there is no drywall on the ceiling or walls.
I dont want to put to much money into this garage because in a couple years I am planning on tearing it down and rebuilding a larger garage, but I would like to try to help the problems I am having now until I get to that point.
