Wet basement

[flying belgian]

At one of my rentals the parking lot goes rt to the house foundation. The blacktop flares up just a wee bit but if it rains hard it runs down the foundation and gets the basement wet. I have put bin tar along the seam but as it dries out it cracks and water again comes in.

How should I tackle that? I'm thinking put some metal flashing down and tar that in or perhaps pour a 2 inch cement curb along wall.

The best thing I've found is urethane caulk.

Is the layout ripe for a French drain or does the grade make that impractical?

Thanks but that won't' work right in this application. I would have to cut a channel or gutter leading to that drain.

Changing the grade to slope away from the building for a few feet has worked the best for me.

Kinda figured you'd already considered that option but never hurts to check.

Maybe put some lead flashing in that and tar underneath it Easy to work with.

Don't know what lead flashing is. Where would I get it? Home Depot?

 

[joeysmith]

Have you checked with a foundation company or slab jacking company?

Maybe they have something to pump down in deeper an be more permanent

I checked their site . Not cheap but a 12"x20' roll is $199.00

Hope this helps

I was going to suggest a concrete curb, but I see you're in MN, so the frost would probably destroy that over time.

Butyl caulk stays flexible forever.

On our barn the tin flashing worked for a long time.

What is the vertical surface you are trying to seal up to, concrete block, or ??

Yes, concrete block. So what was the sealant you used to hold the flashing in place?

 

[paul]

Yea, ours was the wood planks that was the side of the barn. Good goop and nailed the tin on.

It won't work, or you don't want to put in the work to make it work and cut into your rental profits?

Without seeing the problem, it's near impossible to recommend a valid remedy.
