It is an essential home improvement task to waterproof your basement. The damage to the structure and mould caused by long-term moisture can be dangerous. Foundation repair can be expensive, and you can prevent such damages by basement waterproofing process.

What is basement waterproofing?

Waterproofing refers to treating your basement/structure to stop moisture from entering. Water usually starts in the lowest point of the structure, often the basement. Your home could be at risk from water seepage upwards if it is underground or near a low-water table. Leaky pipes or ducts, cracks in walls, leaky water pipes, poor ventilation, old drafty windows, and other problems can allow moisture into your home. Mould and mildew can also grow in poorly ventilated basements. So, you need to install a proper ventilation system in your basement to keep your property safe.

Where does all the water originate?

Locating the source of water is the first step in waterproofing. Basements can become moist for many reasons, particularly below grade. The possibility of basement issues is increased by residing in an area with a high water table.

Groundwater can build up around foundation walls. The chance of cracking walls increases due to this pressure. You must be extra careful if your basement was not waterproofed before construction. Most basement moisture problems are caused by:

  • Improper exterior grading
  • Insufficient air conditioning/circulation
  • Colder surface temperatures
  • Inadequate guttering and downspouts
  • Fans, dehumidifiers and air purifiers can all help to ventilate your basement.

For the best way to locate the water source, make sure you check all your pipes, windows, and walls for leaks. These are visible signs of moisture:

  • White streaks of a powdery substance (called efflorescence) can be seen on the walls. This happens as the water dries.
  • Fungal growth can cause a musty odour.
  • Visual wetness is when water seeps through the windows and walls.

What are the possible risks linked with a damp basement?

A damp basement can cause serious structural damage and health problems. Structural damage can cause your foundation to crack, and you can find severe leakages in your basement. You ccan prevent such problems by installing waterproofing layers on your basement.

How to waterproof my home?

You must find and fix any leaks. Cracks in walls should be filled. After removing the water, you can apply masonry waterproofing material to the interior walls.

  • Exterior waterproofing is done by digging at the foundation.
  • Interior waterproofing is the process of removing moisture from a basement.
  • Mitigation Actions
  • Proper grading of the home is important to keep moisture out.
  • Cleaning, repairing or installing gutters and downspouts.
  • Exterior and interior waterproofing using filler, sealer and/or waterproof painting
  • Basement ventilation systems, basement conditioning systems or basement dehumidifiers are all options to drain water from your basement.

The Prominent Reason for Basement Waterproofing

The basement is more than just a place to store things you do not wish to see. Your basement area is also the foundation of your home. This is enough reason to waterproof basements. But there are other ways this precaution could help protect your home.

Prevent Flooding

Basement waterproofing can help protect your home against water damage, which could cause irreparable damage to any valuables stored there.

Prevent Mold & Mildew

Even if your basement is not flooding, water from rain or snow can cause moisture buildup. This could cause mould and mildew growths that can lead to health problems such as skin irritation and allergies, asthma attacks, and even worsening of asthma symptoms.

Foundation Crack Prevention

Moisture can get trapped in the basement foundation’s porous surface. Repairing foundation leaks and waterproofing basement spaces can reduce the risk of expensive foundation damage.

Reduce Energy Costs

Warm basements can increase humidity, making it more costly to cool down in the summer. Alternately, cracks in the foundation could allow cold air to enter your home despite all your efforts to keep it warm.


Basement waterproofing can be an easy way to extend the life of your foundation or building. It’s a great way of preventing water seepage and flooding. Waterproofing can keep pests and mould away. You will also enjoy lower energy costs and reduced damage repair costs by waterproofing your basement. Waterproofing can increase your property’s value.
