I need help! Possible leak coming between slab foundation and sill plate. I removed the baseboard and I can see the tiny bit of water seeping in. The area is above grade but the foundation does extend 4-5 inches beyond the house wall framing. (It looks like they were going to add brick to the outside and changed their mind.)
From the exterior you can see where the slab foundation meets the wall of ?concrete board?. If I press really hard the wall has a tiny little give to it. Making me believe the seam between the wall and slab is the source of water.
Removed the siding and the wood shows no sign of moisture damage. (yeah, no Tyvek) The concrete board goes up about 6-7 inches which is above where the vinyl siding starts. (of course the j channel is missing too) Just as a precaution, I sealed all seams with the waterproof adhesive tape that you use around doors and windows before putting the siding back on.
Previous owner was an idiot with repairs. Honestly, silicone was his best friend. When I see caulking I know there is another problem. He caulked the interior of this wall with about 2 cans of caulk as a barrier for the water to stay behind the wall. He also used thinset or something like that on the exterior to seal the wall to the slab to keep water out of the seam. Of course this is all flaking off.
This is an old picture The door is watertight now. I already replaced the door and removed the flaking concrete by the threshold.
Help!! I don't want to silicone everything from the inside, I want to keep the water out. What can I use to make a permanent waterproof seal on the exterior joint where the wall meets the slab?
Thanks, Paula
