The next big task was to fix the cracks in the basement walls. I'm sure all basements have a few hairline cracks. Usually, if they're not 'moving' (getting bigger) or leaking, you don't need to worry about them. Unfortunately with these, I noticed some discoloration indicating that moisture is getting in.
Discoloration like this means water is getting
through the crack- even if you can't see or feel it!
A couple of years ago, we actually had some dampness on the floor by the bigger crack, but haven't noticed anything since. Nonetheless, I thought I'd better fix them now.
After researching the various products available, I decided to go with Drylok Fast Plug (a fast-setting hydraulic cement) to seal the cracks. I purchased a gallon at Lowe's for about $14, and with cement chisel and hammer in hand, began to open up the crack enough to get the cement in.
Since both cracks were from ceiling to floor, it took quite awhile to chisel them out. I could have just repaired the area near the discolorations, but figured it was better to do the whole thing.
Following the directions on the can, I mixed the 3 parts solution with one part water. I sprayed down the area to get the cement to adhere properly. I applied the Drylok using a putty knife (3") as recommended. It took about an hour to fill both cracks. Now the walls are sealed and ready for framing!
