Thanks for the reply -

I've attached a photo. What do I use a barrier between the sheathing and the concrete?

Thanks again millworkman -

Is the lot graded properly? It wouldn’t appear so.

That is not sheathing that is T-111 siding. The bottom of the wall should have a pressure treated sill plate with the siding sheets help up off the cement so it doesn't wick water. That being said it seems obvious that water is sitting there as opposed to draining. What is this structure and how about a shot from back a bit further?

Addition done by a previous owner.

Every time I try to post a picture, it won't post.

Finally figured out how to make it work!

You can see from the reflection in the window how the original house was built. I'm working on ways to keep the water from pooling there in heavy rains.

Any ideas on sealing the bottom edge of the T111?

Thanks -

Not going to happen. It needs to be raised up higher. You will not seal it effectively if it continues to sit in or on water.

HU.....459, you have to put some distance between the bottom of the siding & the ground. Looking at your second photo, I'm almost sure that part of the siding has been replaced once already, probably for the same reason that it needs to be replaced now.

You need to put some distance (like at least 6") between the bottom of the siding & the ground for a couple of reasons. Water damage and termites.

How far above grade is the sill plate?

Install rain gutters. Regrade so the ground slopes away from the house. Why is the cement there? Is the area with the damaged siding the inside corner of an L-shaped house?

I have buried a french drain (I think that's what it's called) to help with draining. The back yard slopes toward the house so I've dug and concreted a pit where I installed a floated sump pump. The water is sent to the other side of the carport and down the driveway. I'm working on a similar system for this area of the addition. There is an in-ground pool in the back yard so grading the slope isn't really an option.

Almost forgot - gutters are in the plan as well. That way I can divert the water directly into the pit.

I really appreciate your time and input.

Thanks
