Waterproofing your basement is crucial to avoid flood, leak, or damp problem, and the associated issues that come with them. But sadly, it can be easy to overlook your basement if you rarely use it.
For example, you may only wander down into your basement a couple of times a year to put old clothes into storage or unearth an old sports trophy. Even then, you may not notice signs of moisture-related damage when you’re only in your basement for a few moments.
However, any leaks, floods, or dampness in your basement can cause severe problems over time, from mould growth to harming the property’s structural integrity. Fortunately, waterproofing your basement can protect your home against these issues, and exterior waterproofing is a popular solution.
But how does it work?
In this post, Aluneed’s experts will explore the most important reasons why you should use exterior waterproofing and how it works.

Why Do You Need to Waterproof Your Basement?

Here are some of the most important benefits of waterproofing your basement:

  • Protect your basement and your property’s foundation from leaky pipes and flooding caused by rain or storms.
  • You may increase the value of your home if you invest in high-quality basement waterproofing. Potential buyers will be reassured that they don’t need to handle it themselves, at least for some time.
  • Prevent the formation and build-up of mold, which can lead to health problems including coughing, wheezing, eye irritation, and exacerbation of asthma symptoms.
  • Reduce the danger of structural damage caused by damp and mold, both of which can lead to rot.
  • Cultivate a cleaner, more inviting basement that you feel comfortable using. This will open up extra space in your home, potentially allowing you to add to its value further.
  • Protect possessions stored in the basement from exposure to water and mold.
  • Avoid the expense of dealing with a flood: as reported by Global News, Canadian homeowners pay $43,000 on average to repair flooded basements.
  • Your foundation will stay dry and won’t become weakened or damaged by moisture over the years.

Waterproofing your basement can make a huge difference to your property’s condition and value. You can choose from interior waterproofing, exterior waterproofing, or both.
Interior waterproofing is designed to reroute any water that penetrates your basement back outside and away from your property. It involves creating trenches messing 6 to 8” along foundation walls, as well as installing a drainage membrane and weeping tile system.

What is Exterior Waterproofing?

Exterior waterproofing is different from interior waterproofing in that it prevents water from getting into your basement in the first place.
Exterior waterproofing typically consists of multiple components that work together to keep water out of your basement. A key part of this is the weeping tile: this is a porous drainage pipe installed around your property’s foundation. It will be buried in a trench and covered with dirt and gravel.
As the weeping tile collects groundwater, it will redirect it away from your property into another area, such as your yard or a sump pit. The weeping tile must be tested after installation to ensure that it drains water away effectively and efficiently.
It’s also vital that any existing cracks or holes in the property foundation are sealed to prevent water leaking into them.

How Else Can You Reduce the Risk of Your Basement Flooding?

Gutters are an essential addition to properties to reduce the likelihood of a flood or leak. They are designed to catch water running off your roof, as will happen constantly during a severe downpour, and direct it away from your property.
Your gutters should be connected to downspouts that channel water a few feet from your home, far enough away to keep it out of your basement. You may extend your downspouts to create a bigger gap between your property and any water deposited onto the ground.
It’s also important to clear debris (e.g. leaves) out of your gutters and clean them routinely, otherwise they may become backed up. A sump pump is a must, too. Installing a sump pump in your basement will drain water and redirect it elsewhere.
