Garage Foundation Construction Winnipeg

Winnipeg’s Trusted Garage Foundation Contractors

We understand what Winnipeg’s freeze-thaw cycles, heavy snow loads, and shifting clay soils can do to a poorly built garage foundation. Our experienced team builds durable foundations that prevent cracking, sinking, and water intrusion for decades to come.

We construct foundations for:

• Detached single and double garages

• Attached garages for new home builds

• Garage additions on existing homes

• Heated and unheated garage floors

• Garage pads with footings or thickened edges

Whether you need a monolithic slab, stem wall foundation, or ICF garage foundation, we design it to last.

Types of Garage Foundations We Build

1. Thickened Edge Slab (Monolithic Slab Foundation)

A popular option for garages, especially detached ones. This single-pour system combines the slab and footing, saving time and money.

Features:

• Reinforced perimeter edges (thicker concrete)

• Excellent for level, well-drained lots

• Fastest to install

• Ideal for most standard garage sizes

2. Stem Wall Foundation

Includes a slab poured inside concrete or block perimeter walls.

Best for:

• Uneven or sloped sites

• Heavier structures

• Areas prone to frost heave

• Attached garages needing alignment with existing structures

3. ICF Garage Foundation

Insulated Concrete Forms (ICF) provide superior thermal insulation and moisture control—perfect for heated garages or energy-efficient builds.

Benefits:

• Reduces heat loss

• Minimizes condensation and mildew

• Adds long-term value and comfort

We’ll recommend the right system based on your lot conditions, usage, and long-term goals.

Garage Foundation Replacement Services

Have an old garage with a crumbling, cracked, or sunken foundation? We provide full garage foundation replacement services.

Signs You May Need a New Foundation:

• Major floor cracks or heaving

• Water pooling in corners or near walls

• Uneven surfaces making it hard to open the garage door

• Foundation walls bowing or deteriorating

• Sinking or sloping slabs

• Detached garage shifting away from base

We handle full removals, jack-and-lift jobs, and new construction from scratch.

Concrete Pads for Garage Floors

We also install concrete pads for garages, either as part of new builds or garage flooring upgrades.

Our garage concrete pads include:

• 4”–6” thick slab depending on usage

• Optional rebar grid or mesh reinforcement

• Compacted gravel base for drainage

• Expansion/control joints to reduce cracking

• Laser-leveled finish for smooth flooring

Whether you’re storing vehicles, setting up a workshop, or planning to heat your garage, we can customize your concrete pad accordingly.

What’s the Best Foundation for a Garage in Winnipeg?

Due to Winnipeg’s cold winters and expansive clay soils, your foundation needs to:

• Include frost protection (minimum 4 ft depth or insulation)

• Handle snow load and freeze-thaw cycles

• Resist water seepage and ground movement

• Be built with proper gravel compaction and drainage

For most garages, a frost-protected monolithic slab or stem wall foundation with rebar provides the best balance of performance and value.
