Need ideas on waterproof board to cover water damaged base of outside doors

[Tom Bender]

Do whatever to the shop door first. You will learn from that and do as well or better on the house door.

[roman brisk]

first of all you should block the way of water coming to the door.

You have a water problem, not a door problem. Fix the water problem or this will just happen again, and again, and again.

All that said, a fiberglass door replacement would work for the back door. They are about $600 at most home centers.

Gulvit can be a very helpful product. I have used it to extend the life of masonite and OSB siding that has started to deteriorate with good results.

Hardie board clapboard. I often see broken lengths in the cheap cart at HD.

A few pictures of the doors to show the type and extent of the damage would be useful.

Quarter inch Azek board caulked to exclude water at the joint and screwed in place would do the trick nicely.

I'd replace the slabs.

Why is it you don't want to do that?

[Stan Calow]

How about a clear waterproofing, like Flex Seal?
