Good evening.
I’m looking for a solution to an unfortunate problem.
My friend is converting a 1920s era stand alone barn/garage into a workshop space in Connecticut. Construction is already underway. Unfortunately last week she got several inches of rain and a huge puddle (pond) formed by the front doors (on the gable end) and got high enough to come into the garage. This is only the second time this has happened in five years.
The entire lot is pretty flat, and there is even a slight uphill grade to the street. The back yard gets a big puddle frequently, but this driveway pond only occurs when the ground is frozen and then there is a load of rain. Any re-grading may just force that water into the main house basement (fieldstone foundation)
The garage is built on a slab. A new floor system has been put down w/2×6 joists. Vapor barrier on slab, 2″ foam board between joists and plywood subfloor (to be painted).
The doors are barn style and go to the slab, but don’t fit together tightly. Last week’s water soaked the joists and EPS so the contractor just ripped up a good bit of the new subfloor to dry it all out.
The question is, how do they build what amounts to a dam on the face of the barn to keep the area under the floor dry?? No water came in from the other sides-just the front.
Pour a mini (6″) foundation wall and shift the rim joist up to rest on it?
Use some sort of a membrane like EPMD?
Any ideas would be appreciated.
Thanks
Chris

Sounds like they are framing a floor up over the slab and raising floor.
So easy to pour a curb at the entry doors. Cut a keyway, drill dowel some steel in, and form and mix 2-3 bags of Sakrete. Paint over exterior with Thoroseal

French drain.
Excavate a trench, line with gravel, place in perf pipe, cover with drain cloth, cover with gravel, and lay outlets to drain in lower places in the yard.
That will be $7000 please.

Fortunately, I got the digging done before the first significant rain of the season I bought the house, so nothing in the garage got wet. :)

Why can't you just build a dam of sorts a few feet away? Or install a grate system in front and drain it away?
You can always apply some sort of membrane to the walls, like a rubber roof, but it won't solve the door problem.
