What You Should Know About Waterproofing Basement Walls

For homeowners, nothing can be more frustrating than seeing water getting into your basement and pooling on the floor. If left unaddressed, a leaky basement can lead to a plethora of issues, including damaging the foundation and structure of your home and interfering with the electrical wiring.

WHAT CAUSES MOISTURE IN THE BASEMENT?

Perhaps you are wondering, why is your basement even leaking in the first place? There are several possible culprits.

The top causes of water seepage and a leaky basement include:

  • Excessive condensation.
  • Cracks along the basement walls, floors, and around the windows and doors.
  • The ground around the basement has a wrong slope.
  • Inadequate soil and drainage systems.
  • Poorly installed and maintained gutters.
  • Hydrostatic pressure due to the accumulation of water around the foundation of your home.

WHAT ARE THE DIFFERENT BASEMENT WATERPROOFING METHODS?

As mentioned earlier, there are different ways to waterproof your basement. One is not better than the other, and it all comes down to your needs and basement situation. We give you a quick rundown of each approach below.

OPTION 1: INTERIOR WATERPROOFING

As the name suggests, this involves waterproofing your basement from the inside. Of the three methods, interior waterproofing is perhaps the easiest and most affordable to do. In essence, it entails creating a waterproofing membrane around the basement walls and floors. It may also require the installation of drainage systems, which will be explained in greater detail later on.

The first step is to ensure that there are no cracks or holes in any part of the basement, including the walls, floors, windows, and doors. Any openings are sealed and made watertight using special sealants and coatings. These materials can prevent the moisture from accessing the basement interior, as well as help lower humidity levels and prevent condensation.

The downside is that simple interior waterproofing methods often don’t address the root cause of the leaking, merely acting as a band-aid solution. This is because these underlying problems are typically found on the outside of the basement.

Keep in mind, however, that interior waterproofing methods involving the installation of drain systems are far more extensive.

OPTION 2: EXTERIOR WATERPROOFING

As mentioned above, the culprit behind moisture-ridden basements is usually located outside. In this case, exterior waterproofing is what you need. This method is on a much larger scale and requires some demolition. As might be expected, it is also more expensive.

Exterior waterproofing typically involves excavating the soil around the foundation of your home. This procedure is labour-intensive and also requires the use of heavy tools and equipment. After removing the surrounding soil, the labourers will dig a trench on the outer perimeter of the foundation and fill it with the appropriate drain materials, including drainage tiles and gravel.

After the excavation work, the external walls will be thoroughly cleaned and inspected for cracks. Depending on the condition of your basement, the crew may apply a coat of hydraulic cement and a special sealant to the basement walls, creating an impermeable barrier.

A note on the gutter work:

When it comes to external basement waterproofing methods, it is important to look into the gutter systems as well. A functional and properly maintained gutter system does a great job in steering rainwater away from your basement. If incorrectly installed, on the other hand, it can get clogged or drain water along the foundation of your home.

With that being said, you want to ensure that the gutters near your premises are clean and in working order at all times. It is also recommended to have downspouts or drainpipes that deposit the water away from your home.

OPTION 3: WATER SEEPAGE OR WATER DRAINAGE SYSTEMS

In many homes, improper drainage is often the cause of leaky basements. If so, the solution is to set up a reliable drainage system, which is meant to direct water away from the foundation of your home.

Several types of basement drainage systems exist, including a floor drain, sump pump, and French drain. A floor drain system is often installed during the construction of your home. Meanwhile, a sump pump and a French drain system are usually laid down during the interior waterproofing process. These drain systems are essentially designed to collect water from around the foundation of your home and release it away from your basement.

Of the two, sump pumps are more commonly used. They play a critical role in managing the flow of water in your basement. For best results, use a high-quality pump and install it as close to the foundation as possible. If you already have an existing sump pump, make sure that it is still in top condition. Otherwise, you will have to replace it with a new one.

Installing a drainage system during the interior waterproofing typically involves the following:

  • Digging a trench around the perimeter of the interior basement walls.
  • Setting up the drainage system in the trench.
  • Backfilling the trench with concrete.
  • Applying sealants, if necessary.

WATERPROOFING BASEMENT WALLS THE RIGHT WAY

In recent years, people have become more aware of the importance of basements. As a result, many Canadian homeowners are giving their basements a major makeover, allowing them to be used for a variety of purposes. Indeed, a finished basement can hold several things – from gym equipment to entertainment centres to apartment furniture. But the last thing you want to find in your basement is standing water – alongside obvious signs of mould and mildew.

Lucky for you, there are plenty of basement waterproofing solutions available. By and large, it all boils down to diverting water away from your home and ensuring that no moisture can penetrate your foundation walls.

It is important to remember that there is no one-size-fits-all approach, and it varies greatly from one home to another. For some, the application of chemical sealants will suffice, while for others, there is a need to do some demolition and excavation. You may even have to set up a functional drainage system.

Perhaps the most important thing of all is to find a trusted basement renovation company or a licensed professional. Ensure that they have the right certifications and plenty of experience to back up their claims. After performing a thorough inspection of your basement, your chosen company will recommend a waterproofing solution that best suits your needs and situation. With a reputable company, you can rest easy knowing that the solution is appropriate, meant to last, and worth your every penny. Contact Basement Renovations Now.
