I am going to be finishing the basement and have one problem. The rear wall will leak occasionally. It will usually only happen in a real heavy storm or a strong 'noreaster' (which I think the wall faces). In the basement you will see a slight trickle seeping the LENGTH of the wall all along the sill plate area. I greatly diminished the frequency of this by extending the drain by about 3-4 ft and trying to rake the ground to grade away so no water puddles against the house. Thing is, when we opened a section of the wall by a window while doing some work, and it rained heavy, I think I may have noticed some dripping down from the balloon frame(?)(between brick veneer and frame). I obviously want to resolve this before finishing the wall. Can it be seeping in from outside brick wall? Can bad gutters cause this? How would I troubleshoot?
Thank you

Roach,

water will go through brick. Try the easy things first. Check caulking on all windows and doors. If needed caulk with one part urethane caulk. SIKA, sonneborne and tremco are three good ones. Next seal the brick. Use a siloxane sealer. Alcohol based 20% solution. Follow all manufacturers guidelines.

Hope this helps.

Keith, Thanks for your reply. I have to admit, I'm learning a heck of a lot from this site. I had new replacement windows put in last year and the outside sill on the capping (i think its called that) would slope inwards so that water would collect on the sills. I spent some time to caulk over all the seams and anywhere where I could think water would come in. I do have a feeling that it's seeping in from the bricks and I suppose that a few settlement cracks in the pointing don't help either. I hope to have those pointed. You mention sealing the bricks. How do I do that? I assume I need to hire someone for that. Any idea what kind of cost to expect? I would estimate the rear wall to be 25ft by 30ft.

David,
Look for a construction specialties store in your area. AH Harris is one I know that is in New York.
Siloxane can be sprayed with pump up garden sprayer. It does have some cautions to follow and a respirator is a must.

Any constructions specialties company that provides concrete accesories can get you the product and info.

Good Luck

Keith

Thanks again.
I just saw it mentioned on some other post that sealing bricks would not be recommended. He said that while bricks are porous, they are supposed to breathe and if you seal them, it will cause more damage in the long run. is this true?
