Load-Bearing Support Without Excavation

Advanced Home Solutions installs helical footings throughout Duluth for homeowners adding decks, sunrooms, or structural additions where traditional concrete footings are impractical or where soil conditions limit load-bearing capacity. You may be working with sandy soil that does not compact well, clay that shifts with moisture changes, or sites where bedrock is too deep for standard excavation. Helical footings are steel shafts with welded helical plates that are rotated into the ground until they reach stable soil or bedrock, providing immediate load-bearing support without waiting for concrete to cure.

The installation involves driving the helical shaft into the ground using hydraulic equipment that monitors torque to confirm the footing has reached sufficient resistance. Once in place, the shaft is cut to the required height and capped with a bracket that connects to the beam or post. The depth varies depending on soil type and the load being supported, but the process is faster and less disruptive than digging and pouring concrete footings. Helical footings work in all soil types and can be installed year-round, including in frozen ground where traditional footing installation is not possible.

Reach out to Advanced Home Solutions if you need load-bearing support evaluated for a deck, addition, or foundation project in Duluth.

How Helical Footings Perform Over Time

You will notice that the supported structure remains level and does not settle, tilt, or shift as the ground freezes and thaws. The footings do not heave upward in winter or sink in spring, and they do not require ongoing adjustment once installed. Because the helical plates anchor below the frost line and in stable soil, they resist the movement that often affects shallow or improperly installed footings.

Advanced Home Solutions uses helical footings for both new construction and retrofit applications, including stabilizing existing foundations that have settled or supporting new structural loads added to older homes. The footings are rated for specific load capacities, and installation torque is documented to confirm each footing meets the required specification. Multiple footings are installed in a grid or perimeter layout depending on the structure being supported.

The service includes site evaluation, footing installation, and bracket attachment, but does not include framing, decking, or concrete piers. If the project requires additional structural engineering or permits, those steps must be completed before installation begins. Helical footings are compatible with most framing systems and can be adjusted for sloped sites or uneven terrain.

Homeowners in Duluth often ask about installation time, load capacity, and how helical footings compare to poured concrete.

Questions About Helical Footing Installation

What is the load capacity of a helical footing?

Capacity depends on shaft diameter, helix size, and soil conditions, with most residential installations rated between 5,000 and 15,000 pounds per footing.

How long does it take to install footings for a typical deck?

Most deck projects require four to eight footings and are completed in one day, including setup, installation, and bracket attachment.

When is a helical footing preferred over a concrete footing?

Helical footings are used when soil is unstable, access is limited, frost depth is significant, or immediate load-bearing capacity is needed without waiting for concrete to cure.

Why does installation torque matter?

Torque readings confirm that the helix has reached stable soil and is capable of supporting the specified load, with higher torque indicating better resistance and capacity.

What happens if the soil is too soft at the required depth?

The footing is driven deeper until it reaches adequate resistance, or a larger helix diameter is used to increase surface area and load distribution.
