What is Basement Waterproofing All About?

Basement waterproofing helps you to protect your home from leaks, water damage, and the dreaded mould and mildew. We often say that a wet basement causes inconvenience, but there’s more to it. It can completely damage your foundation and impact your family’s health. And the issues don’t stop here, a wet basement can lower your home’s value, leading you to future disappointments.

However, with basement waterproofing you can get rid of all these issues and lead a happy and healthy life at home. And the best part about this proactive process is that it can be done either from the inside or the outside, depending on the problem.

Knowing About Basement Waterproofing From Inside

Interior waterproofing does not stop water from reaching your foundation, but it keeps it from sneaking into your living space. This method is great for tackling minor issues like damp spots or small leaks without digging up your yard and involves two main procedures:

• Sealing Walls and Floors
  Products like waterproof paint, concrete sealers, or coatings are applied to the walls and floors inside your basement. These create a barrier that blocks moisture from coming through tiny cracks or porous surfaces. It’s a quick and efficient way to give your basement a fresh start!
• Adding Drains and Sump Pumps
  Drains and sump pumps work like a dream team to collect and remove water before it becomes a problem. If your basement has ever felt like a swimming pool during heavy rain, this system is your saviour. It ensures water doesn’t stick around long enough to cause trouble.

Since interior waterproofing happens inside your home, there’s no need for heavy machinery or major excavation. It’s fast, less expensive, and perfect for homeowners who need a hassle-free solution. Plus, you won’t have to worry about your landscaping getting torn up!

Cost of Waterproofing the Basement From the Inside

The cost of waterproofing the basement from the inside depends on a few factors:

• the size of your basement,
• the severity of the issue, and
• methods used to keep that water at bay.

If you’re dealing with minor seepage or damp walls, interior waterproofing solutions like applying waterproof paint or sealants are more like a quick fix. These options are budget-friendly and perfect for addressing smaller issues. However, if the problem runs deeper—literally—you might need more extensive measures like installing a sump pump or a drainage system.

All About Basement Waterproofing From Outside

While interior waterproofing focuses on damage control, exterior waterproofing takes the fight to the source. This method keeps water away from your foundation entirely, offering a more permanent solution. It’s ideal for homes with serious water problems or properties in flood-prone areas. This method involves two main procedures:

• Sealing the Foundation from the Outside
  This involves digging around your foundation to apply a waterproof membrane and seal cracks. Think of it as wrapping your home in a water-resistant jacket that protects it from rain, snow, and groundwater. It’s a bigger job but delivers unmatched peace of mind.
• Installing Weeping Tiles
  A weeping tile system is installed to redirect water away from your foundation, keeping it from pooling around your home. It’s a smart, proactive way to prevent future water damage before it starts.

While exterior waterproofing takes more time and effort, it’s worth it for its durability and effectiveness. If you’re planning a major renovation or building a new home, this is the way to go for all-around protection.

Cost of Waterproofing the Basement From the Outside

Waterproofing your basement comes with a more significant investment compared to interior solutions.

Why the higher price tag?

External waterproofing involves digging around your foundation to access the source of the problem. This means excavation, applying waterproof membranes, installing drainage systems like weeping tiles, and sealing every potential entry point for water. The process is thorough and long-lasting, but it’s also more labor-intensive, especially if your property is large or has limited access.
