Foundation Waterproofing Winnipeg

Why Foundation Waterproofing Is Critical in Winnipeg

Winnipeg foundations are exposed to:

• Expansive clay soil that traps water

• High water tables in many neighborhoods

• Extreme freeze–thaw cycles

• Aging concrete and block foundations

Without proper waterproofing, moisture finds its way inside through cracks, porous concrete, cold joints, and foundation penetrations. Over time, this leads to structural damage, mold growth, and costly repairs.

Foundation waterproofing is not cosmetic—it is structural protection.

Common Signs You Need Foundation Waterproofing

If you notice any of the following, waterproofing should be addressed immediately:

• Water leaking through basement walls

• Basement leaks during heavy rain

• Cracks in basement floor leaking water

• Wet or damp basement walls

• Water seeping through foundation cracks

• Basement leaking from floor or wall joints

• Standing water or recurring dampness

• Moldy smells or visible mold

• Peeling paint or efflorescence on walls

These issues almost always worsen over time if left untreated.

Our Foundation Waterproofing Services

We offer interior and exterior foundation waterproofing solutions based on the cause of the leak, foundation type, and soil conditions.

Basement Foundation Waterproofing

Basement waterproofing focuses on preventing water from entering through walls, floors, and joints.

Services include:

• Basement wall crack repair

• Basement floor crack sealing

• Injection waterproofing for active leaks

• Sealing basement walls

• Waterproofing basement floors

• Interior drainage solutions

Exterior Foundation Waterproofing

Exterior waterproofing is the most comprehensive solution and stops water before it ever reaches your foundation.

This includes:

• Excavation down to footing level

• Cleaning and repairing foundation walls

• Application of waterproof membranes

• Installation of foundation water barriers

• Exterior foundation drainage systems

• Proper backfilling and grading

Exterior waterproofing is ideal for severe or recurring basement water problems.

Interior Foundation Waterproofing

Interior solutions are used when exterior excavation isn’t practical.

These systems manage water after it enters and include:

• Interior drainage channels

• Sump pump systems

• Basement injection waterproofing

• Sealing foundation cracks from inside

Interior waterproofing is effective when combined with crack repair and proper moisture control.

Foundation Crack Repair & Sealing

Cracks are one of the most common sources of leaks.

We repair:

• Basement wall cracks

• Floor cracks leaking water

• Foundation cracks caused by settlement

• Cold joint leaks

Using professional-grade epoxy and polyurethane injections, we permanently seal cracks instead of masking them.

Crawl Space & Foundation Waterproofing

Crawl spaces are especially vulnerable to moisture.

We provide:

• Crawlspace foundation repair

• Crawl space waterproofing

• Vapor barrier installation

• Drainage and moisture control

Proper crawl space waterproofing protects both your foundation and indoor air quality.

Basement Leak Repair – Fixing the Root Cause

Many homeowners try temporary solutions like sealants or coatings that fail after one season. We focus on basement leak repair that addresses why water is entering, not just where it shows up.

Our process includes:

• Identifying hydrostatic pressure points

• Tracing water entry paths

• Repairing cracks, joints, and porous concrete

• Installing drainage where required

This approach ensures long-term protection.
