What’s Basement Waterproofing?

Simply put, it’s a way to stop water from getting into your basement. Think of it like putting on a raincoat for your house’s bottom floor. It’s important because a wet basement can cause all sorts of problems.

Why Should You Care?

A damp basement isn’t just annoying. It can:

  • Make your house smell musty
  • Ruin your stuff
  • Attract bugs and mold
  • Lower your home’s value

So, let’s dive in and see if waterproofing really helps!

Understanding Basement Moisture Problems

Before we talk about fixing the problem, let’s look at why basements get wet in the first place.

Common Causes of Wet Basements

  1. Rain and Melting Snow: Water from outside can seep in through cracks.
  2. Poor Drainage: If water doesn’t flow away from your house, it might end up in your basement.
  3. High Water Table: Sometimes, there’s just too much water in the ground.
  4. Plumbing Leaks: Broken pipes can cause big problems.

Signs Your Basement Has a Water Problem

Look out for these clues:

  • Damp spots on walls or floors
  • Mold or mildew smell
  • Water stains
  • Peeling paint or wallpaper
  • Rust on metal things in the basement

What Happens If You Ignore It?

Ignoring a wet basement is like ignoring a toothache. It only gets worse! You might end up with:

  • Mold growth (yuck!)
  • Damaged furniture and belongings
  • Weakened house structure
  • Higher energy bills (wet basements are harder to heat)

What is Basement Waterproofing?

Now that we know why basements get wet, let’s talk about how to fix it.

The Basics

Basement waterproofing is all about keeping water out. It’s like building a shield around your basement.

Types of Waterproofing

There are three main ways to waterproof a basement:

  1. Interior Waterproofing: This is done inside your basement.
  2. Exterior Waterproofing: This involves digging around your house to protect it from the outside.
  3. Drainage Systems: These help move water away from your home.

Let’s look at each of these in more detail.


Benefits of Basement Waterproofing

Waterproofing your basement isn’t just about staying dry. It comes with lots of perks!

  1. No More Water Damage: Say goodbye to wet floors and damaged walls.
  2. Better Air: A dry basement means less mold and better air in your whole house.
  3. More Space: You can use your basement for living or storage without worry.
  4. Protected Stuff: Keep your belongings safe from water damage.
  5. Higher Home Value: A dry basement makes your house worth more.

Interior Waterproofing Methods

Let’s start with ways to waterproof from the inside.

Sealants and Coatings

Think of these like paint, but tougher. They create a barrier on your walls to keep water out.


  • Easy to apply
  • Relatively cheap


  • Might not work for big leaks
  • Need to reapply every few years

Crack Injection

This is for when you have cracks in your walls. Special stuff is injected into the cracks to seal them.


  • Good for fixing specific problem areas
  • Can be very effective


  • Only works for cracks, not general dampness

Interior Drainage Systems

These are like gutters for your basement floor. They catch water and lead it to a sump pump.


  • Very effective for ongoing water issues
  • Can handle a lot of water


  • More expensive
  • Might need to break up some floor

Sump Pump Installation

A sump pump is like a water vacuum. It pumps water out of your basement.



  • Great for areas with high water tables
  • Can handle sudden floods


  • Needs electricity to work
  • Requires some maintenance

Exterior Waterproofing Methods

Now let’s look at ways to waterproof from the outside.

Excavation and Foundation Coating

This involves digging around your house and putting a waterproof coating on the outside walls.



  • Very effective
  • Long-lasting


  • Expensive
  • Disruptive to your yard

French Drains

These are pipes buried around your house to carry water away.


  • Good for areas with lots of groundwater
  • Helps with surface water too


  • Requires digging up your yard
  • Can clog over time

Grading and Landscaping Improvements

Sometimes, just changing how your yard slopes can help a lot.


  • Can be simple and cheap
  • Improves your yard’s look


  • Might not be enough for serious problems
  • Depends on your property’s layout

When is Basement Waterproofing Necessary?

Not sure if you need to waterproof? Here’s how to tell:

  1. Check the Severity: If you’re always mopping up water, it’s time to act.
  2. Consider Your Home’s Age: Older homes often need more help.
  3. Think About Where You Live: Some areas are just wetter than others.

If you’re seeing regular dampness or water, it’s probably time to waterproof.

The Waterproofing Process

Curious about what happens when you waterproof? Let’s walk through it.

  1. Inspection: A pro checks out your basement to see what’s wrong.
  2. Choosing a Method: Based on the inspection, you pick the best way to fix it.
  3. Preparation: This might mean moving stuff or digging up your yard.
  4. The Work: Depending on the method, this could take a day or a week.
  5. Clean-up: Everything gets put back in order.
  6. Final Check: Make sure it all works!

DIY vs. Professional Waterproofing

Thinking about doing it yourself? Let’s compare:


DIY Pros:

  • Cheaper
  • You’re in control

  • Might miss important problems
  • Could make mistakes

Professional Pros:

  • Expertise and experience
  • Better equipment
  • Warranties on work

For small jobs, DIY might work. For big problems, calling a pro is usually best.

Maintenance and Upkeep After Waterproofing

Once your basement is waterproofed, you’re not done! Here’s how to keep it dry:

  1. Regular Checks: Look for new cracks or damp spots.
  2. Clean Gutters: Keep water flowing away from your house.
  3. Watch Your Yard: Make sure water isn’t pooling near your foundation.
  4. Test Sump Pumps: If you have one, make sure it’s working.

Common Myths About Basement Waterproofing

Let’s bust some myths!

  1. Myth: All basements leak eventually. Truth: With good waterproofing, they don’t have to.
  2. Myth: Waterproofing is too expensive. Truth: It’s cheaper than fixing water damage later.
  3. Myth: You can just use a dehumidifier instead. Truth: Dehumidifiers help, but don’t fix the root problem.

Cost Considerations

Waterproofing can be pricey, but it’s usually worth it. Here’s what affects the cost:

  • Size of your basement
  • How bad the water problem is
  • What method do you choose
  • Where you live

Think of it as an investment. It can save you money on repairs and increase your home’s value.

Waterproofing isn’t just good for your house – it can be good for the planet too!

Eco-Friendly Options:

  • Water-based sealants
  • Recycled materials for drainage systems

Energy Efficiency: A dry basement is easier to heat and cool, saving energy.

Choosing a Waterproofing Contractor

If you’re hiring a pro, here’s what to look for:

  • Licensed and insured
  • Good reviews and references
  • Clear, detailed quotes
  • Warranty on their work

Questions to Ask:

  1. How long have you been in business?

  3. What method do you recommend for my basement?
  4. How long will the work take?
  5. What’s your warranty like?

Alternative Solutions to Full Waterproofing

Not ready for full waterproofing? Try these:

  1. Dehumidifiers: Great for mild dampness
  2. Better Ventilation: Open windows or use fans to move air
  3. Fix Small Issues: Seal small cracks, fix leaky pipes

These can help, but they’re not as good as full waterproofing for serious problems.
