Why Bolton Basements Leak — and Why Foundation Cracks Are the #1 Cause
Many Bolton homes, especially those built since the 1970s, are constructed on poured concrete foundation walls. Over time, normal settling and shrinkage create vertical or diagonal cracks in the concrete. When the soil on the outside of your foundation becomes saturated, water penetrates these cracks and leaks into your basement.
In Bolton and nearby Caledon communities, we commonly see:
- Leaking vertical foundation cracks behind finished walls
- Diagonal cracks from corners of basement windows
- Tie-rod hole leaks in poured concrete foundations
- Cove joint seepage where the basement floor meets the foundation wall
- Window well leaks during heavy rain or snow melt
Most poured concrete foundation leaks can be repaired permanently with our high-pressure polyurethane crack injection method — from inside your basement, in a single visit.

Leaking Wall Crack
Most Bolton homes built since the 1970s develop foundation cracks due to concrete shrinkage during curing and foundation settlement. Local clay soils hold a lot of water, and these cracks usually leak most during heavy rainfall or spring melt.

Window Well Leak
Bolton homes on sloped lots or walkout-style basements often experience window-well flooding due to poor drainage. When the window well fills with water, it rises and enters your basement beneath the window frame.

Tie-Rod Hole or Snap-Rod Leak
Bolton poured concrete foundations commonly have tie-rod holes and snap-rods that leak when hydrostatic pressure builds up around the home. It’s common to have multiple tie-rod and snap-rod leaks in the same basement.

Floor–Wall Joint Leak
Where the basement floor meets the foundation wall, seepage is common in Bolton due to water buildup in the weeping tile. This type of leak often shows up as a puddle or staining along the perimeter of your basement.

Water Over the Wall
In some Bolton homes, water spills over the top of the foundation wall due to excessively high exterior grading, poor sealing around patio doors, and incorrect step installations. This often shows up as staining along the top of the foundation wall.

Moldy or Damaged Drywall
Swollen baseboards, peeling and yellowing paint, or moldy drywall in a Bolton basement often mean that something is leaking behind finished walls — usually a crack, tie-rod hole, or floor–wall joint seepage, and sometimes plumbing leaks.

At AquaGuard Injection & Waterproofing®, foundation crack injection has been our specialty since 2002. We use professional high-pressure equipment to inject expanding polyurethane resin into leaking cracks in your Bolton poured concrete foundation walls.
Here’s how our Bolton crack injection works:
- We expose and clean the crack on the inside wall.
- An epoxy sealant is applied to the surface of the crack.
- Injection packers are installed along the length of the crack.
- The crack is flushed with acid and rinsed with water.
- We inject expanding polyurethane resin under pressure into each channel.
- The expanded resin fills the crack through the full thickness of the wall.
- Once cured, the crack is permanently sealed against water infiltration.
How Much Does Foundation Crack Repair Cost in Bolton?
Most standard foundation crack injection repairs in Bolton start around $745 + HST for a typical vertical crack that is fully accessible from inside the basement.
Pricing factors include:
- Length and width of the crack
- Shrinkage crack vs. settlement crack
- Finished vs. unfinished walls
- Number of cracks needing repair
