Water Stains or Efflorescence on Concrete Walls

basement wall leak

Beware of potential “Water stains” or Water Stains or Efflorescence on Concrete Walls, a white chalky residue, on your basement’s concrete before you close in the walls or cover the concrete floor.

A few things the look for or look out for:

Stains on the concrete wall 

Stains on the concrete wall is usually due to water entry through small defects that would normally go unnoticed when dry. These stains can be identified by standing back from the concrete wall and looking for a darker colour or even brown if dirt has been washed in. Staining usually will be directly under the defect such as a well line or sewer pipe that runs through the wall, a metal tie, or even a crack in the wall that normally comes off the corner of a window, near the center of the wall. Even if there are no signs of leaking; it is necessary to address these before they leak and ruin the new walls, flooring, and belongings.

Run water around the outside of the basement 15-20 minutes per side

If there is a leak issue, running water on the exterior concrete wall will cause water seepage on the interior concrete wall.  If you see leaking in the basement, move your hose to the next area and mark on the wall the upper most point of leakage and call in the professionals.

If you’re going to spend money on repairs, make sure it is done by “the pros” with a good warranty. When deciding who to use, we advise getting three estimates and a request for references. Check with BBB for a clear history.  For the benefit of your investment, DON’T panic and pick the first company that arrives.

Get informed and choose wisely! Do not gamble and hope to get lucky (That’s what Vegas is for).

Basement Leaks; A Homeowner’s Worst Nightmare

Basement Leaks Happens To Every Homeowner!

We’ve all had that moment when we ventured into the basement only to find wet clothes in the laundry room, a wet carpet in the family room, or ever worse, a flood that has ruined our valuable keepsakes in the storage area!  Yes, basement leaks can be a homeowner’s worst nightmare.

It doesn’t matter if your home is old or newly constructed, you’re going to experience foundation cracks sooner or later for a variety of reasons.

How to Repair a Foundation Crack.

There are several products available to the consumer to fix foundation cracks.  However, most of the products tend to be a temporary fix to a much larger issue.   There are several types of foundation cracks and there is a specialized way to deal with every circumstance.  This is why it is important to have an expert evaluate the crack before jumping into any quick foundation repair fixes. Most professional companies that do this will also offer a warranty on the repair work. Wise Cracks not only offers a warranty on their work, it is also transferable to the next owner.

Types of Foundation Cracks and What You Should Know

Basement-Leak-Repair-Shrinkage Crack

Shrinkage Foundation Cracks

Shrinkage Foundation Cracks generally happen in newly poured foundation as the concrete shrinks and cures into position.  Normally shrinkage cracks can be found in the centre of the third length of the foundation and they do not extend along the surface.   They do not affect the structural integrity of the building but will cause water seepage.



Basement-Leak-Repair-horizontal crack

Horizontal Foundation Cracks

Horizontal cracks is a result of the pressure applied on the exterior foundation wall.  This type of crack is uncommon and sometimes occur because of the poured wall originally being back filled too soon.  This type of crack rarely has any ongoing movement because the only movement would be against gravity.



Basement Leak Repair Settlement Crack

Settlement Foundation Cracks

Every building shifts into position.  Settlement foundation cracks are in most cases vertical in length and runs completely through the structure.   These are most often caused by structural problems pushing in on the wall due to freeze thaw movement. For example, an outside retaining wall attached to the foundation that is not heated can lift and will cause movement if left uncorrected. We have solution for such situations.
