Question DetailsAsked on 10/18/2015

I'm checking into waterproofing my basement and wondered is Drylok the best option? I don't have water coming .

I have two dehumidifers running and my electric bill is sky high. I talked to different waterproofing company and got the drylok isn't a good idea. The one today said as long as I have a french irrigation system, drylok will work.

Do you have the same question? Follow this Question

If the water is against your wall and the moisture is coming through the block then Drylok will waterproof your wall, but it won't take the pressure of water off of your wall which could lead to failure of the wall itself; which is why the contractor said it would work with a french drain to divert water away from your foundation first. You should find a way to keep the water from making its way to the wall itself, but in doing that there should be no reason to use Drylok. Any waterproofing company that is even worth considering will tell you that you need to keep the water away from your wall itself, which is why they don't recommend Drylok.


If moisture is making its way from below (or does make its way down to your wall) you'll need a drainage system by the base of your foundation and diverted to a sump pump to be pushed away from the basement. If you can keep as much of the water as possible away from your basement wall or floor you shouldn't even need to use a dehumidifier. Of course some of these options can get very expensive, very quickly, so make sure you get opinions and quotes from at least 3 different companies. It sounds like you've already talked to 2 so you are on the right track.


You should be asking these contractors where they think the water (moisture) is coming from and how their solution will work in your case. Just a general synopsis will suffice.

Good comments by DriverNerd - you can find more detailed discussions of the ways to handle basement moisture issues, ventilation versus dehumidifcation vs water infiltration prevention, and various ways to prevent the water from even getting to the foundation walls, which as he says is by far the best way to handle it is possible. And that is almost always possible unless your house is down in a hole so your foundation is the local drainage sump, or you have chronically (or seasonally) high groundwater and the soil permeability is so high that exterior french drains will not lower it satisfactorily.
