If you have ever wondered where you could add extra living space or store your belongings without creating chaos or crowding your current living area, the basement in your own home might be a perfect solution. However, one persistent issue many home owners face is water intrusion especially in areas where the water table is high or those prone to flooding. This can lead to problems like mold growth and structural damage, due to moisture seepage into the basement ultimately creating an unhealthy living environment for the homeowners. In order to counter this, there is an effective method in place called exterior basement waterproofing. This method, though elaborate, is one of the most efficient ways to keep the basement moisture free and structurally sound.
In this blog, we will explore the intricacies of exterior basement waterproofing, delve into its advantages and drawbacks, and answer key questions such as how does exterior basement waterproofing work, and provide insights into our waterproofing methods at Basement Finishing to help you decide if this approach is right for your basement.
I. Understanding Exterior Basement Waterproofing
Exterior basement waterproofing is like giving your home a raincoat. It is a preventive method where we apply protective materials to the outside of your basement walls to keep water from seeping in.
The main goal?
To keep your basement dry and cozy, no matter how much it rains or how high the groundwater gets.
How it differs from interior waterproofing
Think of interior waterproofing as using an umbrella indoors. It might help a bit, but it is not stopping the rain from getting in. Exterior waterproofing, on the other hand, is a proactive method by not allowing the water to enter the basement in the first place. It’s like building a barrier around your home to keep water out completely. This approach makes it one of the best waterproofing for basement exteriors, offering long-lasting protection.
Common materials used in exterior waterproofing
We’ve got quite a few tools in our waterproofing toolbox:
- Waterproof membranes: These are like thick, sturdy stickers that we apply to your foundation walls.
- Liquid rubber: This stuff goes on wet and dries into a flexible, waterproof layer.
- Bentonite clay: It’s a natural material that expands when wet, creating a water-tight seal.
II. Causes of Basement Wall Damage
Basement walls are always at risk of damage, making waterproofing essential. The following are some key causes that highlight the need for it:
Hydrostatic Pressure
The amount of water around your home determines the pressure on your basement walls. Therefore it is important to address the issue, otherwise, it may lead to cracks over time.
Soil Erosion
Does soil erosion play a major role in the damage? Absolutely. Foundation weakness can lead to basement wall damage as the underlying soil erodes, making it more susceptible to water intrusion.
Freeze-Thaw Cycles
When your house is in an area with common cold temperatures, there is always a risk of soil freezing. Frozen soil expands, adding extra stress to the basement walls.
Improper Grading and Poor Construction
Does your ground slope towards your house? If so, it means the grading is improper, which can cause water to flow into the foundation instead of being channeled away. This issue may result from poor construction or the age of the home.
III. How Does Exterior Basement Waterproofing Work?
The following provides an overview of exterior basement waterproofing, highlighting its role as a comprehensive system that offers long-term waterproofing benefits for your home.
Excavation and preparation
First things first, we need to dig. We will excavate around your foundation, exposing the walls that need waterproofing. It’s a bit like archaeology but instead of looking for dinosaur bones or ancient relics, we are preparing the foundation to protect your home.
Cleaning and Repairing
Once exposed, the walls are thoroughly cleaned and examined for any cracks or damage. If any major or minor damage is found, we use specialized sealants to repair it, preventing any structural issues once the pillars are erected later on.
Application of waterproof membranes
Once we’ve got a clean slate to work with, we’ll apply the waterproof membrane. This is where the magic happens. We carefully cover every inch of your exposed foundation walls with this protective layer.
Installation of drainage systems
Water needs somewhere to go, right? That’s where a good drainage system comes in. We’ll install pipes and gravel along with drain tiles or French drains to guide water away from your foundation. It would feel like a proper river channel that is created around your home to ensure a proper drainage of water to keep the basement dry and structurally sound.
Backfilling with Proper Soil
The dug-up trench is refilled with gravel or soil to facilitate drainage, reducing water accumulation near the foundation and helping maintain its structural integrity.
IV. Long Term Waterproofing Benefits (Exterior Basement Waterproofing)
Basement Water Damage Prevention
Exterior waterproofing is like building a fortress around your home. Once it’s done, you can rest easy knowing your basement is protected for years to come. No more worrying every time it rains!
Preservation of foundation integrity
Water can be sneaky. It can slowly wear away at your foundation, causing cracks and weakening your home’s structure. Exterior waterproofing puts a stop to that, keeping your foundation strong and stable.
Increased property value
A dry basement is a valuable basement. By investing in exterior waterproofing, you’re not just protecting your home – you’re boosting its value. It’s a win-win situation!
V. Drawbacks and Challenges
Higher initial costs
I won’t sugarcoat it – exterior waterproofing can be pricey upfront. It’s a big job that requires specialized skills and materials. But remember, it’s an investment in your home’s future.
Disruption to landscaping and outdoor spaces
Remember that excavation we talked about? Well, it means your yard might look a bit like a construction site for a while. Your prized petunias might need to take a short vacation.
Weather-dependent installation process
We can’t control the weather. Rain or freezing temperatures can put a damper on the waterproofing process, potentially causing delays.
Effectiveness in different soil types
Some soils are thirstier than others. Clay soil, for example, holds onto water like a sponge. In these cases, exterior waterproofing really shines, providing a robust barrier against persistent moisture.
VI. Comparing Exterior and Interior Waterproofing Methods
Impact on basement living space
Interior waterproofing often means installing systems inside your basement, which can eat into your living space. Exterior methods keep all the protective measures outside, leaving your basement free for that home theater you’ve been dreaming about.
Long-term maintenance requirements
Once exterior waterproofing is done, it’s pretty much set it and forget it. Interior systems often need more ongoing care and attention. It’s the difference between planting a cactus and caring for an orchid.
VII. When to Consider Exterior Basement Waterproofing
Signs of severe water intrusion
If your basement feels more like an indoor pool after heavy rain, it’s time to consider exterior waterproofing. Other signs include persistent musty odors, visible mold, or efflorescence (those white, chalky stains on your walls).
Planning for basement renovations
Thinking about turning your basement into a cozy living space? Waterproofing should be your first step. It’s much easier (and cheaper) to waterproof before you start decorating.
Preventive measures for new constructions
If you’re building a new home, exterior waterproofing is a no-brainer. It’s much easier to do it right from the start than to fix problems later.
