Many homeowners make the mistake of leaving their wet basements unattended. Some fear that waterproofing might be costly. However, the more damaged your home becomes, the more expensive future costs will be.

In addition to preventing future costs, there are a few other reasons why you should consider basement waterproofing.

• Damage to Foundation

A wet basement can wreak havoc on your foundation. It damages its structural integrity, which can lead to further damage throughout the home. A faulty foundation is not only dangerous, but it also decreases the overall value of the property.

• Health Problems

Wet basements have been associated with a range of respiratory conditions. This is because they increase humidity in the home and create an ideal environment for mildew and mold to grow.

• Increases Heating Costs

The humid air that wet basements bring can drive up your heating costs. Humidity can force your heating system to work twice as hard, which increases your monthly bill.


Finding the origin of a leakage in your basement can be tricky. This is why it is advisable to get a professional to find the source of the water. While it might be obvious in some cases, others are not so clear. A thorough diagnosis needs to be conducted to deal with the problem effectively

Common sources of water leakages include:

  • Cracks in the foundation walls
  • Cracks in the floor and/or windows
  • Cove joints
  • Mortar joints

Cracks in the foundation walls
Cracks are one of the most common sources of water seepage. Luckily, they are also the easiest to identify. This is because water entering through cracks tends to leave stains on the foundation wall. Cracks usual occur in unfinished basements but can be caused by several other factors.
Cracks in the floor and/or windows

Water can seep in just as easily through cracked floors and windows. Homeowners must be aware that the water does not necessarily settle where the crack is. A puddle on the basement floor, for instance, might not be from a crack in the floor. This is why a professional’s expertise is required.

Cove joints
A cove joint is the point where the foundation wall meets the basement floor. This is a common leakage in areas that experience high volumes of rainfall and snow. When it rains or snow melts over an extended period of time, the water underneath the floors is forced by hydrostatic pressure into the basement.

Mortar joints
The top of your foundation can also be a point of entry for the water in the basement. The foundation top is also known as the mortar joint. It is susceptible to water seepage if the soil outside (the grade) surrounds the top of your foundation and gravitates water from rain, snow and gutters towards it.


Leakage problems in your basement can be remedied by a range of waterproofing solutions. Although many homeowners think it is cost effective to do it themselves at home, it is highly advisable to contact an experienced contractor.

Depending on the source of the leakage, a waterproofing solution will be applied to either the interior or exterior of your home. Here are some solutions a contractor might suggest.

Epoxy/Urethane Sealants
Epoxy and Urethane are two popular sealants contractors use to close the cracks in the wall. Epoxy injections do a thorough job with sealing cracks in the foundation wall from the interior of the home. Because of its strength, it is usually used on concrete walls and offers stable protection against leakages.

Urethane sealants are just as efficient as epoxy injections. The main difference between the two is that urethane is more flexible. If, for any reason, the foundation shifts over time, urethane maintain contact with the foundation wall.

Epoxy, on the other hand, is rigid and cannot move with a shifting foundation.
Once used separately, epoxy and urethane are now used together to provide the best basement waterproofing. Epoxy is normally applied first and then followed by a urethane sealant to provide protection, flexibility and durability.

Wall Clay Sealants
While epoxy/urethane sealants are used in the interior of the home, wall clay solutions seal cracks from the exterior. The wall clay process involve boring a hole in the crack and filling it with a clay solution. This creates a durable, waterproof barrier between the exterior and interior of the home.

Sump Pump/French Drain
A sump pump, also known as a French drain, provides protection against water seepage caused by hydrostatic pressure. In a nutshell, a sump pump is a drain installed at the central point of the basement to extract water that seeps in through the floor. It is the ideal solution for homes in areas with a wet or cold climate.

Subsoil Membrane
If the source of your wet basement is the exterior grade, then a contractor is likely to recommend a subsoil membrane. This membrane is applied to the point where soil meets the foundation to keep water out. Because of its flexible composition, it can be used on foundations made of brick, concrete and stone.

Sealants, pumps and subsoil membranes are just a few of the many waterproofing solutions available. It is best to ask a trained contractor to inspect the home and recommend the solution suited to your needs.

Choosing the Right Basement Waterproofing Solution

Choosing a waterproofing solution is best left to professionals. Because there is no knowing which solution is right until after inspection, it is wise to request a consultation first. After the property has been checked and a diagnosis provided, the contractor should be able to suggest an affordable solution to make your basement 100% waterproof.
