What Is Efflorescence?

Efflorescence is a white powdery substance that appears on concrete surfaces like your basement walls and floors. It occurs when water penetrates concrete and reacts with naturally occurring salts. When the water evaporates, it leaves behind salt deposits.

Efflorescence looks unsightly, but you can clean it off surfaces with water, white vinegar, and a strong brush. However, you’ll still need to address its root cause—excess moisture.

Here are some other red flags that indicate you have basement moisture problems in your Alberta home:

If ignored, excess moisture will damage your home’s foundation. So, consider contacting a local basement waterproofing specialist like Groundworks as soon as possible.

Causes of Efflorescence

The reason for efflorescence in your basement is moisture intrusion, which can happen for the following reasons:

Basement walls with black mold and signs of efflorescence.
  • Cracked floors or walls
  • Inadequate construction
  • Failing waterproofing systems
  • Capillary action in porous concrete walls 
  • Elevated groundwater levels
  • Flooding or water accumulation due to rain or melting snow
  • Failing gutters and downspouts
  • Leaky plumbing or home appliances
  • Indoor condensation and high humidity

Can You Fix Efflorescence?

The good news is that you can brush efflorescence off walls and floors pretty easily. However, you need to deal with the moisture that caused this problem in the first place. Otherwise, efflorescence will just come back again.

Basement waterproofing stops moisture intrusion for good. This process involves drying out your basement, sealing gaps and cracks, and preventing water from entering your home.

The work done promptly by Ryan and his team (Eryica, Ny) was excellent with the driveway lift that was extremely necessary. The team did a great job being on time and within the time allotted to complete the work. Would recommend to others if they need a professional job done while being efficient. Thank you again!

We got 3 quotes for driveway lifting. These guys were competitively priced and had good reviews on google so we hired them. I’m glad we did! They were very friendly, professional, and efficient. They did a great job and cleaned up afterwards. When James and his partner came back to seal the joints, the service was just as good as the first team. Thanks again!

Excellent service. Sales was pleasant and quote was thorough enough to proceed. The crew that came out to excavate, and install the interior and exterior basement systems was absolutely top notch – their work was neat and tidy, they showed up on time, and worked hard. To top it off, they (and all the folks involved) have to be the most pleasant contractors I’ve ever dealt with – and this is house #5 for us over the years! Thank you, Basement Authority. Highly recommend.
