Basement Waterproofing

Basement waterproofing is the first most important step that must be taken before you begin any basement remodeling project. Otherwise, moist and water will ruin your finished basement over time. We offer a variety of both interior and exterior wet basement solutions. Our promise is that your basement will stay dry – always.

Why is Waterproofing My Basement Important?

Did you know as many as 60% of all U.S. homes have or will experience a wet basement? This is according to the estimates of the American Society of Home Inspectors.

Waterproofing is important because it protects both your family’s health and the integrity of your basement foundation. Water and ongoing dampness can have lasting effects on the integrity of your basement structure. If left untreated, serious issues can arise. Mold and mildew can cause harm to your family’s health. Water leakage can weaken and damage the basement floors and walls. You must address these issues right away.

If you are considering a basement renovation project, waterproofing is an important first step you must take. Whether you want to add an extra bedroom, home office, a theater or a workout room, your finished basement gives you an incredible variety of potential options that you otherwise wouldn’t have. Taking the first steps to waterproof the basement before renovating gives you peace of mind that your basement will be protected from water damage.

How Do I Prevent Water from Getting into My Basement?

In order to keep water out of your basement, we will provide both interior and exterior waterproofing solutions.

Here’s a quick overview of the basement waterproofing repairs you might need:

  • Interior Waterproofing Systems — Could include installing a sump pump, waterproofing panels, or using interior excavating to install French drains.


  • Exterior Waterproofing Systems  —Installing a waterproofing membrane. Involves clay that creates a waterproof barrier. The process entails excavating. Prior to adding the waterproof seal to the exterior of the basement walls, we will first patch any weak points or cracks in the foundation walls.

How Do I Know If I Have Moisture in My Basement?

There are a variety of visual signs which indicate potential basement water damage including:

  • Water stains or dampness on the walls or floor
  • Condensation on the windows
  • A musty smell
  • Evidence of mold
  • Peeling or bubbling paint on the walls
  • Rot in the corner boards
  • Rust around a steel support column
  • Curling or loose floor tiles

Any manner of moisture in your basement may result into a number of problems. This could include structural damage to the foundation, the formation of mold & mildew, along with health issues. Always remember that even though your basement is not your main living area, a damp basement or mold could significantly affect the quality of air your family breathes in the rest of the home above. Don’t delay and take action now.

How Much Does Basement Waterproofing Cost?

We measure the cost per linear foot. The following are the approximate average costs for both interior and exterior wet basement solutions. However, keep in mind that some variations in cost may vary depending on the repairs required.

  • Exterior Waterproofing Cost – $125-150 per linear foot
  • Interior Waterproofing Cost – $45-60 per linear foot

We will have to evaluate the reason why your basement is experiencing leaks or dampness in the first place. The appropriate solution can vary but may include one or more of the following:

Cement Waterproofing

This is a cost effective solution but has some drawbacks. Cement sealer waterproofing involves a cementitious solution. It is a thick coat which we would apply to the exterior walls of the basement. This form of concrete waterproofing may be the easiest means to prevent water leakage. This solution can be used for both full basements and crawl spaces. It is cost effective because a 5 gallon of mix covers 100 square feet and costs around $40.

The drawback is that the cement mixture becomes completely hard. Any movement caused by frost for example or a shifting of joints can cause cracks to form. We generally only recommend this solution for dry climates and if your soil is a sandy loam mixture. The environment must be right to avoid expansion or contraction to maintain the integrity of the cement waterproofing.

Foundation Waterproofing Membrane

This is a more effective but also a more expensive option. The process requires excavation, the addition of drainage panels along with application of the membrane itself. Total cost for a waterproofing membrane can run as high as $15,000. However, it is also one of the best waterproofing solutions you can use to keep your basement dry.

Exterior Weeping Tiles

Another wet basement solution is to remove the water so it does not have the ability to seep into your basement walls. Weeping tiles are not really tiles. They are actually plastic pipes which have perforated holes that are regularly interspaced. The water enters these pipes and is directed away from the home. They are an excellent solution for any form of concrete foundation such as basements and crawlspaces.

Weeping tiles need to be installed correctly with the right materials and grading. You can use this solution in addition to using either a cement sealer or the application of an exterior membrane.

Concrete Waterproofing & Foundation Coatings

A form of concrete waterproofing that uses the same approach as the basement sealer we described earlier. The only difference is that instead of applying the sealer to the exterior, we would apply the sealer to the interior basement. This can be effective because a thick coat on the interior walls will act as an additional barrier should the exterior sealer barrier become compromised.

Silicate Concrete Sealers

Another similar approach to the concrete sealer. The difference is that a silicate concrete sealer penetrates the pores of the walls while chemically reacting with the concrete. The sealer does not affect the appearance of the walls and increases the ability of the concrete to remain dry. It has the added bonus in allowing the walls to breathe because it lets moisture escape instead of trapping the damp inside the walls.

Basement Waterproofing Paint

A very cost effective solution and the easiest way to prevent dampness is to simply use paint to act as a substitute sealant. But, the right paint must be applied because not any old paint will do. The paint must be acrylic to form the right form of bond to prevent moisture seepage.
