A bit unusual to pour a slab, meant for a building, not to be 6" above
grade
for the finish surface at its lowest point. Read over your replies to
others. The slab is about 4 years old. Yet, the garage was built 1.5
years
ago. In the interim, between the garage slab and the garage building
erection, something may have happened. An overzealouz landscaper may
have
added topsoil, and as a consequence, the lack of above ground clearance
as
an example.. This is not the fault of the contractor who built the
garage.
If the slab holds the same top surface to soil grade as when is was
poured,
there may be a detail or two that the slab contractor and owner failed
to
communicate to each other.

Slab sounds like a basic flat, level +/- 1/8". No provision for a car
to
drive into, no downsloped apron. So, don't see any problem except that
what
was allowed by the person who orginally contracted the slab.

#15 building felt is commonly used under the bottom (sill) plate before
erecting the walls. Gonna be fun trying to get that under there now.

All true... Bad planning on my part. I would have expected the contractor
to
point out any flaws in my plan, but I assume he just did what he was told.

Vinyl siding is loosely attached to walls. Was not meant to keep out
water
in the form of melted snow pressed against the vinyl siding. Its needs
a
continuous vapor barrier between the vinyl siding and the sheathing.

Garage has Tyvec wrap under the siding.



If you have any house wrap laying around, take a real close look at it. Its
woven plastic. Now, imagine water type hydraulic pressure from the side if
this housewrap is on the walls. Not hard to believe this water is seeping
in.
