The first order of business when installing basement walls is to make sure it’s properly waterproofed. The easiest way is to hire a local professional to do this for you. The advantage of calling the professionals is knowing the job was done right, the first time. The last thing you want is to have your walls built and find out the leaks weren’t fixed. If you’d rather waterproof the basement yourself, here is a quick guide.
I recommend using the SaniTred (sanitred.com) solutions as that company specializes in Do-It-Yourself Waterproofing.
- Your basement needs to be dry, empty, and all crumbling materials, dust, dirt, etc needs to be gone. Sour your basement a few times just to make sure this is complete.
- Add one coat of PermaFlex to the walls then check for missed spots.
- Add a second coat of PermaFlex when the first layer has sufficiently dried.
- Use a liquid rubber base with a thickening aviator to fill all cracks, creases, seams, joints, etc. Also – use this to fill any holes, rough spots, or crumbling areas in the basement. Special focus where the floor meets the walls.
- Add another layer of Permaflex to act as the top coat
