concrete against wood?????

[lowell66dart]

My pole barn builder will come in and set the poles and bottom girt and then go work on someone else's barn for a few days. That's when I will pour the slab. The bottom girt will basically be my form board and stay there. I don't know if I'm overthinking this but I want to put something between the concrete and the wood. I guess 30lb. tarpaper would work but does anyone know of something more durable that i could use. Something around an 1/8 of and inch thick that doesn't absorb moisture. Someone mentioned using the foam underlayment that's used on the snap together flooring.

There's a product called "sill seal", basically a roll of foam that might be what you're looking for. You can get it in various widths.

It's intended to go under sill plates.

The big box stores have it.

I'll check it out, thanks.

There is a product made that will do what you want, Its called expansion joint material. Make sure your board is made of treated lumber also.

Pressure treated lumber will do fine by itself. Make sure the nails or lags used to secure them are at least galvanized.

I am in the process of pouring a concrete 'curb' around the inside perimeter of my pole barn. The bottom girt was fine against the concrete, but is rotting from below from being outside over dirt for 20 years. If I were to do it over, I'd have formed a few inches OUTSIDE the sheathing & allowed the pour to flow out under the sheathing to seal to the building. Otherwise, the critters squeeze in.

To keep things as dry as possible around the outside I was thinking about using some metal landscape edging about 12 inches away from the edges of the building and put pea gravel or limestone down. I'm hoping that will keep things drained, dry and plus no damage to the building from weedeaters, mowers, etc. The property is perfectly flat and I will have a good slope from the edges. It will be good Mississippi River sand that drains well.

+1 on the expansion joint and treated lumber.
