upper garage w/ wood floor?

[iowasq]

hey guys....i'll be closing on our new house wed and i'm already buying stuff for the new shop ....there is however, one issue...the floor of the upper garage is wood. it's a 24x30 on a hill...driveway goes into the upper section, downstairs is empty at the moment, but will be where the magic happens. it's basically built like a house, cinder block lower, studs upper, but with a pretty substantial increase in floor strength(guessing 2x12s ~12" apart)...there are a couple places where you can see water gets through to the lower level.

so the actual question.....what can i use to fill these gaps that's still going to be semi-flexible, but not look like a 4 year old went crazy with a tube of caulk?

The basic answer is IntegraFlex 1921... But, there may even be some better recommendations depending on PICS!

Not sure it was a good idea but a friend that had an old garage with the same setup had the upper floor blacktopped.

I would suggest going on the underside and using duct tape to 'plug' the holes where you will then go upstairs and use a URETHANE CAULK. Most Box store will have it the urethane is CRAZY flexible and Sticks GREAT to wood.

Depending on the viscosity the tape will hold it in place until it sets.

The first thing I thought of was truck bed liner. If you could find someone with a mobile spray on setup that would work great .

Is the deck solid lumber? If so than it will expand and contract with seasonal changes in moisture. That could make if difficult to caulk. How about laying down a membrane of ice shield (roofing product) and cover it with T&G plywood decking. Glass cloth the seams and maybe pour on an epoxy floor?

Is it enclosed or open?How about a layer of concrete?Don't laugh, I worked on a new house a few years ago that had the area under the attached garage excavated,engineered I beam trussjoists on 12" centers and a concrete floor.It added a little over 400 square feet to the basement using space normally wasted by just filling it in with dirt.

That ice shield membrane sounds pretty good to prevent moisture from penetrating into the basement area. I am not sure what the best covering would be for membrane protection and the wear layer. Something breathable would probably be good otherwise moisture could get trapped and cause mold and rot. Tires with grit on them will allow moisture to penetrate any thin covering.

Do you need to regrade or install a drainage system to prevent the water from entering? I would try to prevent the water from ever entering the ground level(upstairs).

Water drips off wet vehicles.
