Mass Pour Underpinning Winnipeg
At Assured Piling, we specialize in mass pour underpinning in Winnipeg for homeowners, property managers, and developers seeking permanent and durable foundation reinforcement. This time-tested method is ideal for stabilizing sinking or compromised foundations while increasing load-bearing capacity. With Manitoba’s ever-changing soil conditions and harsh freeze-thaw cycles, mass concrete underpinning provides a dependable solution to prevent structural failure and future settlement.
Whether you’re dealing with cracked basement walls, sloping floors, or structural instability, we provide mass concrete underpinning services tailored to the specific needs of your structure. Our team brings precision, safety, and engineering-backed strategies to every project, ensuring your foundation receives the reinforcement it truly needs.
What Is Mass Pour Underpinning?
Mass pour underpinning, also known as traditional underpinning, involves excavating sections under the existing foundation and filling them with high-strength concrete in a sequential manner. This technique enhances the foundation’s structural integrity and distributes the building’s weight more evenly to deeper, more stable soil layers.
At Assured Piling, our team performs this process meticulously in phases to avoid compromising the existing structure. It’s particularly suitable for:
Residential homes with shallow foundations
Older homes with failing stone or rubble foundations
Historic buildings
Low-rise commercial structures
If your building is showing signs of foundation failure—like interior cracks, sticking doors, or exterior brick displacement—mass concrete underpinning in Winnipeg could be the long-term solution you need.
Why Choose Mass Pour Underpinning?
There are several underpinning methods available, but mass pour underpinning is still widely preferred for specific scenarios due to its simplicity, proven results, and durability. Here’s why:
No Heavy Equipment Needed: Ideal for tight urban spaces or basements with limited access.
Cost-Effective: Compared to other deep foundation systems, it offers excellent value for smaller residential properties.
Minimal Vibration: Unlike piling, this method is gentle on surrounding structures—especially important for aging or heritage homes.
Engineering-Approved: With the right assessment and soil testing, this method meets engineering standards and city code compliance.
Our Process
At Assured Piling, our mass pour underpinning process follows industry best practices while customizing every step to the unique conditions of your property:
1. Site Inspection & Assessment
Our team begins with an in-depth inspection of the structure, noting signs of settlement, movement, or failure. We then conduct soil testing to understand ground conditions beneath the existing footing.
2. Engineering & Permits
Once suitability is confirmed, we collaborate with structural engineers to finalize designs and acquire any required city permits before breaking ground.
3. Sequential Excavation
We excavate short sections (known as “pins” or “bays”) beneath the footing, no longer than 3-4 feet at a time, ensuring the building remains supported throughout the process.
4. Concrete Pour
Each section is cleaned and reinforced before being poured with concrete. Once cured, adjacent sections are tackled until the entire perimeter is stabilized.
5. Finishing & Clean-Up
We backfill and compact the soil around the new footing, restore disturbed landscaping or basement interiors, and ensure your foundation is ready for decades of safe use.
Common Use Cases for Mass Pour Underpinning in Winnipeg
Due to Winnipeg’s unique climate and soil shifts, mass pour underpinning becomes a reliable fix in many scenarios, such as:
Sinking foundations in older homes
Cracks in plaster or drywall
Doors and windows that don’t align
Tilting chimneys or stair-step brick cracks
Basement water infiltration due to foundation shifts
We’ve served neighborhoods across Winnipeg—from North Kildonan to St. Vital, Fort Garry, and the Exchange District—delivering mass underpinning solutions that last.

When Is Mass Pour Underpinning Not Recommended?
While versatile, mass pour underpinning may not be suitable in all cases, such as:
Large, heavy buildings where deep piling is more appropriate
High-rise towers
Sites with extremely poor or loose soil
In such cases, we might recommend alternative methods like helical pier underpinning, drilled concrete piers, or screw pile systems—all of which we also offer under the Assured Piling brand.
How Much Does Mass Pour Underpinning Cost in Winnipeg?
Every project is unique, but pricing generally depends on:
Length and depth of excavation
Access to the jobsite
Soil conditions
Amount of concrete and reinforcement required
Engineering or permit fees
On average, mass underpinning in Winnipeg may range from $400 to $900 per linear foot, with full-perimeter jobs often starting at $10,000+. We provide free consultations to give you a better idea of scope and pricing.
