5 Highlights on Poured Concrete Foundations

Monolithic wall construction

Legacy General Contractor pours foundation walls in a single continuous pour, creating a seamless structure with no cold joints that could allow water infiltration.

Proper frost depth compliance

All foundations are set below the Minnesota frost line (42-60 inches depending on location), preventing heaving and structural damage from freeze-thaw cycles.

High-strength concrete mix

We use 3,500-4,000 PSI concrete with proper water-cement ratios, ensuring your foundation meets structural requirements for decades.

Steel reinforcement installation

Horizontal and vertical rebar is placed according to engineering specifications, adding tensile strength to resist soil pressure and settling.

Waterproofing and drainage systems

Every foundation includes proper waterproofing membrane application and drainage tile installation to keep your basement dry.

We back every foundation with a written workmanship guarantee. If a defect in our work causes problems, we make it right.

Signs You Need Poured Concrete Foundations

1. You're building a new home or structure

New construction requires a properly engineered foundation. Poured concrete provides superior strength and water resistance compared to block alternatives.

2. Existing foundation shows structural cracks

Horizontal cracks, stair-step cracking, or bowing walls indicate serious structural issues that may require foundation replacement rather than repair.

3. Chronic basement water problems

If waterproofing repairs haven't solved persistent moisture issues, the foundation itself may have integrity problems that require replacement.

4. Adding a major addition to your home

Large additions need new foundation work that properly ties into your existing structure and supports the added load.

Our Poured Concrete Foundations Process

Step 1 — Site Evaluation

We assess soil conditions, review engineering plans, and confirm footing locations and depths before any excavation begins.

Step 2 — Excavation

Our crews excavate to the required depth, ensuring proper clearance for footings and foundation walls.

Step 3 — Footing Installation

Footings are poured and cured before wall forms are set, creating a solid base for the foundation.

Step 4 — Wall Forming and Reinforcement

Steel forms are set to exact dimensions, and rebar is installed according to structural specifications.

Step 5 — Concrete Pour

Foundation walls are poured in a continuous operation, vibrated to eliminate voids, and finished at the top.

Step 6 — Curing and Waterproofing

Walls cure under controlled conditions, then receive waterproofing membrane and drainage system installation.

Step 7 — Inspection and Backfill

Final inspections are completed before careful backfill to protect the waterproofing system.

FAQs About Poured Concrete Foundations

How long does it take to pour a foundation?

A typical residential foundation takes 1-2 days for footings and 1-2 days for walls, plus 7 days minimum cure time before backfill. The complete process from excavation to backfill usually takes 2-3 weeks.

How deep do footings need to be in Minnesota?

Minnesota requires footings to be at least 42 inches below grade in the southern part of the state, and up to 60 inches in northern areas to get below the frost line.

Poured concrete vs. block foundation — which is better?

Poured concrete is generally superior for water resistance and structural strength. It has no mortar joints that can crack or leak, and provides better lateral strength against soil pressure.

How much does a poured concrete foundation cost?

Costs vary based on size, soil conditions, and accessibility. Contact Legacy General Contractor for a detailed estimate based on your specific project requirements.
