Basement Waterproofing Paints - pros and cons
You’ve found water in your basement and now you’re looking for a solution. You may have already called a local waterproofing contractor to get an estimate for your wet basement and the shock of the cost may have sent you directly to your local home center to find a more cost effective solution to fix it yourself. The most common do-it-yourself basement waterproofing products available in home centers are waterproofing paints. This cheap, easy to apply fix peaks the interest of my homeowners looking to waterproof their basement without the big cost of hiring a PRO, but does it work? Will it last? Can it actually waterproof your basement? Well, lets break it down…

Pros of Waterproofing Paints:

  1. Reduces fungal smells by creating an airtight shell over the surface of the basement walls.
  2. Lowers the radiation of humidity by locking the moisture behind the paint surface.
  3. Dampproofs the walls by preventing moisture from passing into the interior of the basement.

Cons of Waterproofing Paints:

  1. Will not waterproof a basement – Waterproofing paints are designed to push hold or plug moisture, but it does not properly manage the water entering the basement, therefore, it is not a long-term solution to dry up a wet basement.
  2. Blistering and shelling – Paint rely on its bond to the wet surface and eventually that bond will way. Over time as the lime in the cement begins to get wet, a white efflorescence will begin to grow between the surface of the concrete and paint creating a large boil or blister, which flakes and shells off.
  3. May generate greater hydrostatic pressure – Block wall foundations have hollow cavities that build up with hydrostatic pressure when moisture is present. Waterproofing paints attempts to hold back moisture, which causes a deeper build up of water and causes greater pressure inside the wall.

Bottom line: Waterproofing paints don’t waterproof your basement, but they will help reduce odors and lower the radiation of humidity in the basement.

Alternatives of Waterproofing Paints:

  1. Contractor installed subfloor system to collect and drain water away.
  2. Manage surface water and runoff to help prevent water from entering the basement.
  3. Install a baseboard channel system to collect water from where the floor and walls meet and channel it to a floor drain or sump pump.

Nemo Winter Snowstorm BlizzardThis past weekend has been filled with snowstorms, rain showers, that yucky sleat and blizzard warnings all across the United States. For many people in the Midwest and East Coast, today is a recovery day to shovel out driveways, sidewalks and asses any damages caused by the several increase of snow fall. Connecticut was especially hit during the Nemo snowstorm, receiving up to 40 inches of snow!

With snow totals near 3 feet in some areas of the country, many homeowners will likely see the after affects with water leaking into the basement over the next couple of weeks. As the hydrostatic pressure building up around a home’s foundation water is forced inside the basement through the joint where the floor and walls meet. To prevent a flood of water entering your basement install a basement waterproofing system that will tap into the source of the basement water and drain it away. The do-it-yourself SquidGee Dry basement waterproofing system is an ideal remedy to a basement leaking water through the joint where the floor and walls meet.

Severe WeatherWeather reports show severe weather headed for the Midwest toward the Mid-Altantic today and tomorrow. They are projecting 90 to 105 miles per hour winds just 5,000 feet above the ground in some areas, which could lead severe wind damage and possible tornados. Heavy rainfalls threaten much of the affected area leading to frozen ground and unsafe driving conditions. Flood watches are also in effect for part of the upper Midwest. Read the full article on The Weather Channel for more details.

Storms and flooding often lead to a wet basement. Here are a few tips to keep your possessions safe from water damage if you do not have a basement waterproofing system installed:

Move items away from the walls. Nine out of ten basements leak water in through the joint where the floor and walls meet. Moving the items away the from the walls will make it easier to remove the water.

Get items up off the floor. Using a few cinder blocks and sheet or two of plywood make a well supported platform to store your items above the floor.

Use a wet vacuum to suck up the water seepage. Another option is a mop and bucket during a power outage.

Monitor your sump pump. If you do not have a high water alarm for your sump pump you will need to monitor your sump pump for failure during a power outage. Having a high water alarm is ideal for every sump pump system, the best option is one that has the ability to call you notifying you that your pump has quit whether you are at home, work or out of the house verus a buzzer noise. A high water alarm is your best defense in a power outage. Instead of purchasing an expensive triple safe back up pump system that only last a few hours, you could purchase a high water alarm, a replacement main sump pump and a generator used to keep power throughout the house that will last much longer.

Install a basement waterproofing system. Every home with a basement needs a basement waterproofing system to protect their investment. There are many options on the market today from professionally installed basement systems to highly effective do-it-yourself basement waterproofing products.


Wet basement in the winterBasements can leak water throughout the year whether moisture present is from rain or snow. But many homeowner’s wonder, why does my basement leak during the winter when their is only snow outside and not puddles from a rainstorm?

During the winter months, basements radiate heat out into the surrounding soil, usually about 8 inches away from the foundation. This heat melts the frozen soil around the basement creating a pocket of moisture. The water becomes trapped between the frozen soil and the basement walls during the winter time. The downward pull of gravity, known as hydrostatic pressure, is what forces the water into the basement creating a leak. This is why basements leak water during the winter months, even if there isn’t a heavy rainstorm or running water outside the foundation.

Most often the leaking water enters the basement where the floor and walls meet or a crack in the wall or mortar joints. This type of water leak is best fixed by relieving the hydrostatic pressure, installing an above floor baseboard channel basement system and sealing the wall cracks from the top to 3 inches above the basement floor. By leaving the bottom 3 inches of the wall crack open, you will allow the water to be collected by the baseboard channel.


New Year Resolutions1. Lose weight and get fit. For many trimming the waist line is a huge goal for 2013. One of the most common reasons weight-loss goals aren’t met is the hassel of going to the gym. Waterproofing your basement can open up that space for anything, including an at home gym!

2. Clear your clutter and get organized. Over the years, basements become the home to many unwanted and poorly organized items. Start your new year off right by clearing out the unwanted stuff to open the space up for organized storage. Since wet basements aren’t a good place to store your valuables, you will need to install a basement waterproofing system to keep your possessions dry and in good condition.

3. Spend more time with friends and family. Do you have a handyman friend? Suggest a you both help each other on your next home improvement project. Invite them over to help you install a basement waterproofing system and in return help them with their next project. It’s a great way to spend time with friends and check off a to-do list project all at once!

4. Take a vacation. Hiring a waterproofing contractor can cost you big money. If you have a basement leaking water in through the joint where the floor and walls meet, an ideal solution is an above floor baseboard channel like the do-it-yourself SquidGee Dry System. A basement with a linear footage of 60 feet would only cost $375 (shipped!) to install the DIY SquidGee Dry System, compared to hiring a PRO, which could cost anywhere from $3,000 to $1,500! That’s a huge savings that could go toward a vacation! Find out what you would save!

5. Learn something new. Learn something new by installation of the SquidGee Dry System. Do-it-yourself installation is easy and only takes a weekend.


waterproof a basementMost homeowner’s first instinct when fixing a wet basement is usually painting, patching or trying to plug up a leak. The trouble with caulking, patching or painting over a leak is they are not long-term solutions to a basement water problem. That is why professional waterproofing contractors don’t offer these services.

These inexpensive “push-back” methods try to keep the water out of a basement, which many homeowner’s believe is the solution to their wet basement. Instead homeowners should think like a professional basement waterproofing contractor to remedy their problem. Choosing a basement waterproofing product that will tap into the basement water and properly manage it is the PRO’s way of waterproofing a basement.

Trying to push back water will not solve the wet basement issue, as water is forced into your home by hydrostatic pressure. A “push-back” basement waterproofing method will not relieve hydrostatic pressure, so water will simply find a new way to enter your basement, which often causes a bigger problem.

The solutions is to tap into the source of the water to relieve hydrostatic pressure by drilling weep holes into the bottom row of cinder blocks. Next, install a baseboard waterproofing system where the floor and basement walls meet. This glue-down baseboard channel system will capture the basement water and direct it to a sump pump system. This type of above floor baseboard channel basement system is a long-term solution to a wet basement. You can even finish a basement once installed.

The SquidGee Dry DIY basement waterproofing system is a contractor-grade product at a do-it-yourself cost to homeowners. To find out what it would cost to install in your wet basement simply measure and total up the perimeter of your basement, count the number of inside and outside corners in your basement and enter those into our Quick Quote basement waterproofing cost calculator for a free estimate in seconds!

Here’s a list of our most frequently asked do-it-yourself basement waterproofing questions this past October. If you have questions about do-it-yourself basement waterproofing we’d be glad to help. You can send us an email or give us a call at 1-800-828-2947!

1. Richard asked, “I was wondering if your [SquidGee Dry] system could be used I a finished basement?”

Yes, you will need to remove the walls and studs 6 inches up from the basement floor to expose the concrete wall. Then install the SquidGee Dry System and refinish over the system. Here’s more information about how to finishing your basement after using the DIY basement waterproofing system.

2. Linda asked, “How smooth does the concrete floor have to be? Will I have to sand or scrape it for the seal to work with the SquidGee Dry basement waterproofing system?”

You do not need to sand the floor smooth, but if there is any paint, glue, etc on the surface you will need to remove that to expose the concrete floor about 3 inches away from the walls.

3. Trevor asked, “Water comes through the walls higher than 5 inches from ground. Will your diy basement waterproofing [SquidGee Dry] system still work ?

The top of the SquidGee Dry System is not glued to the basement wall, therefore, any water seepage down the face of the basement walls or window wells overflowing will be directed back behind the system. You can also install a vapor barrier along the face of the walls and tuck it back behind the system to create a pocket for any wall seepage to travel through.

4. James asked, “How do you allow for drop in the [SquidGee Dry] system for the water to move towards the sump pump?”

The SquidGee Dry System stands 5 inches tall, to create a tall narrow channel for the water to build up and flow out the open end. When the water has stopped flowing out the open end it simply flows back out the weep hole where it came in. To direct the water from the SquidGee Dry System into your sump pump or floor drain, you will need to pick up a round piece of PVC pipe from your local home center. Here is a link on how to drain the diy basement waterproofing system on our site.

4. Eric asked, “The glue [SealOnce Adhesive] compound that is used – will it withstand temperatures near zero degrees? We have a patio area that is under a family room extension. Sometime in future we hope to enclose the area however we need to control the water seapage first from the walls.”

Yes, the glue will withstand the lower temperatures.
