Question To waterproof or not to waterproof

I live in the north east, New York to be exact, I'v never had water in my basement and I'm trying to decide if I should water proof befor I finish it. I do run a dehumidifyer in the summer, it takes care of any smell, my water pipes did swet but I have insulated them and have no problem their, the walls and floor are poured concrete. I have never seen a drop of water and the walls aren't discolored any where.

Bruce P,

I think you know that old saying, an ounce of prevention is worth it's weight in gold or something like that. If you have the opportunity to do it now, I would. Nothing worse than regretting it later after you invest all the time and money to making something nice!

Hope this helps but you probably knew you were going to do it anyway!

To waterproof ...

I'm struggling with the same thing - though I increased my level of effort should I choose to waterproof by having my wall framing done! I've pretty much decided not to do it - never any seepage in the 5 years we've been here, and the cost/effort didn't seem worth it to us.

Best of luck!

Waterproof or not

Masonry tends to transpire humid vapors. You can not see these. There may not be any evidence of moisture. Most forum posters tend to report applying a couple coats of Drylock or other masonry sealer before proceeding with finishing the basement.

Try this little experiment to aid you in making your decision. Take a piece of poly about 4 x 4 feet. Apply it to your concrete wall below grade. Make it as air tight as you can using caulking around the perimeter. Wait & observe. The results will vary with seasons,
