Foundation Repair & Basement Waterproofing in Cornwall, ON
A strong foundation is the most important part of your home. When your foundation cracks, shifts, or begins letting water into your basement, the entire structure is at risk. Moisture intrusion leads to mold, structural movement, damaged finishes, and long-term problems that get worse — and more expensive — over time. Iron Fort Construction & Renovation provides professional foundation repair and basement waterproofing services throughout Cornwall and Eastern Ontario, ensuring your home stays dry, safe, and structurally sound.
We fix foundation issues at their source and install long-lasting waterproofing systems designed to handle the harsh conditions of Ontario’s climate.
Complete Foundation & Basement Waterproofing Solutions
Every home is different. Soil conditions, drainage patterns, concrete age, and water pressure all change how water interacts with your foundation. That’s why Iron Fort delivers custom solutions for each home, based on real inspection results — not guesswork or temporary fixes.
We repair cracks, strengthen weakened foundation walls, stop water entry, and install full waterproofing systems that protect your basement for decades.

Common Foundation & Waterproofing Problems We Fix
Leaking Foundation Cracks
Often caused by water pressure, settlement, or aging concrete.
Basement Dampness & Humidity
A sign of moisture seepage through concrete walls or floors.
Water Pooling Around the Home
Improper grading or poor drainage leads to constant wet walls.
Sump Pump Failures
A failed sump pump can flood a basement in minutes.
Efflorescence (White Powder on Walls)
Indicates water passing through the concrete.
Mold or Musty Odours
Moisture intrusion is nearly always the cause.
Bowing or Shifting Foundation Walls
Serious structural warning sign — must be addressed quickly.
Seasonal Water Infiltration
Common in Cornwall due to clay soil and freeze–thaw cycles.
Whatever the issue, we diagnose it correctly and repair it permanently.
Why Foundation Problems Get Worse Over Time
-
Water is powerful — and once it finds a path into your home, it continues widening it. Small cracks become large cracks. Damp walls turn into leaks. Seasonal moisture becomes year-round damage. As water pushes on foundation walls, it can cause structural movement that becomes extremely costly to fix.
-
Acting early protects your home, your basement, and your investment.
