Foundation Repair & Basement Waterproofing in Cornwall, ON
Fix basement leaks, foundation cracks, and water intrusion before they cause serious structural damage.
A strong foundation is critical to the safety of your home. When foundation cracks, wall movement, or water intrusion begin, the entire structure is at risk. Basement leaks and moisture problems lead to mold, structural damage, and expensive repairs if left untreated. Iron Fort Construction & Renovation provides professional foundation repair and basement waterproofing services throughout Cornwall and Eastern Ontario.
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.
​
Our solutions focus on stopping water at the source and preventing repeat foundation damage.
Our Foundation Repair & Basement Waterproofing Services
Foundation Crack Repair
We repair leaking, structural, and settling cracks using professional injectables and reinforcement methods — not hardware store sealants.
Exterior Basement Waterproofing
The most effective long-term waterproofing solution that protects your home at the source — the outside.
• Excavation around the foundation
• Cleaning and inspecting foundation walls
• Application of waterproof membrane

• Replacement of weeping tile and gravel
• Proper backfilling
Sump Pump Installation & Replacement
We install and replace modern sump pump systems with backup options to protect basements from flooding during power outages and heavy storms.

Foundation Wall Reinforcement

A reliable alternative when exterior excavation is not possible or cost-effective.
• Interior drainage channels
• Sump pit installation
• Weeping tile replacement
• Vapor barriers
• Wall liners
Moisture & Mold Prevention
By keeping water out, we reduce humidity, prevent mold growth, and protect finished and unfinished basements.
Basement Leak Repair
We identify the true source of basement leaks and repair them using long-lasting solutions — not temporary patch jobs.
If foundation issues are caused by active flooding or water damage, our water damage restoration team in Cornwall can respond immediately.
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.
Early diagnosis and proper foundation repair can prevent costly structural and renovation work later.
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.
