Water-Resistant Garage Walls

[Jordon_HTX]

I've got an unfinished detached garage built in 1969 and I'd like to throw up some walls. I currently have one corner that's prone to water intrusions. Seems the garage has settled and is not even with driveway. Water ponds in front of the garage door and frequently flows into the garage. I'm working on adding a sump outside to take care of the ponding.

I don't want to use regular drywall due to the moisture and water intrusion. Any other recommendations for wall material? I've considered exterior gyp board, FRP boards, and OSB.

Thanks!

P.S. this probably isn't a new issue, so if someone has an existing thread they can link me to, that'd be appreciated also.

Is the garage below grade? What does the land do next to the garage? Behind the garage? A sump pump is a solution if there isn't a way to get water to drain naturally. Questions above would be where I'd start though.

Wall coverings really aren't the main issue here. If you're always going to be having water there, then the wall construction may need to be looked at. Getting water away is the first solution, but a secondary solution might be to cut off the lower part of the wall, and put a course or two of block (or pour a stem wall) where the wall is subject to water.

Pictures will help dramatically in getting you advice that's useful for your site.

Are you looking for a waterproof material? Or a moisture resistance material?

Just off the top of my head, tile the walls up 2ft from floor?

Fix the "moisture and water intrusion" problem- there's no problem with d/wall; it's actually better than pretty much any other material- especially from a fire standpoint.

I certainly don't see any reason for a "sump"- a regrade definitely. A sump pit will eventually fail- as would a sump pump. Nature and gravity are your long term friends- use them to your advantage!

MDO Medium Density Overlay. You should be able to get in 1/2" or 3/4" 4x8 sheet

It's has resin-impregnated fiber surface bonded an exterior-grade plywood panel. The surface is very smooth and is similar to a brown paper bag in color. I pay about $60 a sheet for 3/4" and around $45 for 1/2". Now that may sound expensive, but keep in mind that you could put this up and not have to do paint it or do anything else to it.
