Tarring Foundation For Raised Patio...

ruskent

I looked at a raised patio job this week. The patio will be 24inches above grade. I assume it would be best to tar the foundation, correct?

And is it neccessary to tar the foundation if there is no basement?

No, if you have no basement/crawl space you don't have to waterproof the foundation, doing it is better, just to minimize water infiltration and damage, but not needed.
Good Luck!

Don't worry.

The black stuff is really not a waterproofer and is a damp proofer. Most also have a short ilfe. I can make a customer feel good.

Rusk,

Will there still be at least 6" of foundation above the patio height?

There will not be any foundation above the patio. The heights do not work out .

Part of the siding will be cut removed, flashing installed, new j channel installed. I just do not know if this will be along the entire length of the patio or just for the stairs. Again i am not sure on the final height yet.
