Start by Identifying the Type of Crack
Not all wall cracks are the same, so it’s essential to identify the type before deciding on a fix.
- Hairline cracks: Thin and often from normal settling. Usually not serious.
- Vertical cracks: May be caused by soil movement. Monitor for changes.
- Horizontal cracks often indicate soil or water pressure issues, which can be more serious.
- Stair-step cracks: Common in brick or block walls; may signal foundation shift.
If you're unsure, it’s best to consult a professional to determine if wall crack repair is necessary.
Clean and Prepare the Crack Before Repairing
No matter the type of crack, cleaning the area is always the first step. This helps repair materials stick properly. Use a wire brush or vacuum to remove loose material, dust, and dirt. If the crack is damp, let it dry completely.
This may seem like a small step, but it’s a big part of a lasting repair. Without proper prep, even the best products won’t hold up.
Choose the Right Repair Method and Materials
Once the area is prepped, choose the correct repair method based on the crack’s size. Use a flexible sealant for small surface cracks. For larger ones, epoxy or polyurethane injections are more effective. Exterior cracks may require a waterproof membrane to prevent moisture from entering. Using the wrong product can lead to future leaks. For large, leaking, or recurring cracks, it’s best to call a professional. Wall crack repair experts, such as DryShield, handle these issues throughout Toronto.
Add Basement Waterproofing for Long-Term Protection
Fixing the crack is only part of the solution. Adding waterproofing helps keep your basement dry in the future. Toronto homes are often affected by heavy rain and melting snow, which can cause soil movement and increased water pressure around the foundation.
Waterproofing strategies include:
- Interior waterproof coatings – These are applied to basement walls to prevent moisture from entering.
- Exterior membranes – These are applied to the outside of foundation walls to prevent water from entering.
- Drainage systems – Sump pumps and interior drainage channels help move water away from the foundation.
With the right combination of crack repair and waterproofing, your basement remains protected regardless of the season.
Fix Drainage Issues Around the Foundation
Even the best repairs won’t last if water continues to collect around your foundation. Drainage problems are a significant contributor to basement cracks. Here’s what you can do:
- Extend downspouts so water drains at least 6 feet away from your house.
- Make sure your yard slopes away from the foundation.
- Clean gutters regularly to prevent water from overflowing and pooling near the walls.
- Check for low spots around the home that might hold water.
Keeping water away from the foundation reduces pressure on your basement walls, which can help stop new cracks from forming. If you’re in an older Toronto home or notice water pooling after rain, consider investing in drainage improvements.
Monitor Repaired Areas for Changes
After you repair the crack, be sure to monitor it closely. Measure the width and take photos every couple of months. If the crack begins to grow or new cracks appear nearby, this may be a sign of ongoing movement in the foundation.
Early detection makes future repairs easier. In some cases, what appears to be a minor issue may be an early warning sign of a more significant structural problem.
Regular monitoring provides peace of mind and allows you to take action before water or damage spreads.
Schedule Regular Basement Inspections
Basement walls can shift over time, especially in Toronto, where weather conditions cause the soil to expand and contract. It’s a good idea to inspect your basement at least once a year.
During your checkup:
- Look for new or growing cracks
- Check for water stains, damp spots, or mold
- Test for musty smells that may suggest hidden leaks
If anything appears to be off, consult a professional for a thorough inspection. They can recommend the best type of wall crack repair and ensure your foundation remains safe.
Summary!
Cracks in basement walls aren’t always serious, but they should never be ignored. Taking early action with simple cleaning, the proper repair method, and waterproofing can stop bigger problems later on. For Toronto homeowners, where the weather can be unpredictable, regular maintenance and innovative prevention are essential.
