Pros and DIYers commonly use french drains either inside the basement next to the footing or outside the foundation next to the footing. There are many types of drainage systems used and every waterproofer seems to swear by the drainages system that they offer. The two most common systems are made of generic drain pipe.
Be sure to use a drain sleeve for either of the two pipes above.
If you don’t want to do any digging, the following two companies might be worth looking into:
If you have a high water table, these drainage systems that sit on top of your floor probably won’t work…. (just my two cents).
Membrane, Paints, & Sealers
Many professionals use some sort of basement waterproofing membrane. Exterior waterproofers may use tar-based or PVC-based membrane while most interior waterproofers solely use PVC-based membrane.
DIYers tend to mainly use paints like DRYLOK. Many say they have had good luck with it, but personally, I don’t recommend using any paint or rubberized paint inside your basement as your foundation needs the ability to breathe. I’ve been eyeing a Ghost Concrete Sealer instead. If you go the sealer route, make sure that you get the appropriate sealer for your basement, block or poured.
Dehumidifiers are an important part of the basement waterproofing process. Your dehumidifier must have two very important capabilities.
- The ability to self-drain. You do not want a dehumidifier that you have to empty. For one, it’s a pain in the neck. Secondly, it will more than likely get forgotten about causing your dehumidifier to shut off.
- Your dehumidifier must be able to dehumidify your entire basement area, so make sure the dehumidifier rated for the square footage of your basement.
Professionals tend to use higher-end dehumidifiers like SantaFe. From the reviews that I have read online, there doesn’t seem to be much difference between the quality of the expensive brands and the cheaper brands. Whatever route that you choose, make sure your dehumidifier meets the two requirements above.
If you can’t keep the water out of your basement after taking the first steps of basement waterproofing, then you may be in need of a sump pump at some point. The sump pump that you use is also an important part of your basement waterproofing project. Be sure that your sump pump has a battery back up and is sealed from the air space in your basement. Many contractors use a double pump system just in case one the pumps fail.
