Screw Anchors Explained

What Are Screw Anchors?

Screw Anchors used for building deep foundations and strengthening the foundation of the structure. They manufactured using tubular hollow sections. Screw Anchors are handy when it comes to protecting the foundation of the structure and protecting the structure from any damage, screw Anchors employed in both commercial and residential purposes. Screw Anchors applied for both commercials as well as residential uses. Screw Anchors are durable in nature, and their installation process is quick. 

Screw Anchors are also known as Screw Piles, Screw Piers and Ground Screw Anchors


Screw Anchors are used to increasing the strength of the foundation of the structure. Screw Piles are drilled deep inside the surface of the earth to provide support and resistance to the foundation of the structure of all shapes and sizes. In several situations, more than one Screw Anchor installed to support and strengthen the foundation of the building, construction, or bridge.


Screw Anchors manufactured using galvanized steel to protect it from rusting. Generally, they are round hollow shafts or square shafts prepared from steel. They are available in various shapes and diameters as per the requirement of the project. During their fabrication, one or more steel screw threads are welded onto the shaft to enable sufficient downward force into the earth’s surface as it drilled into the surface. The plane kept as per the standards, but the shapes and sizes may vary as per the application. Screw Anchors are long-lasting with a life expectancy of almost more than 100 years, depending upon their usage and load employed.  


Screw Anchors are drilled deep inside the surface of the earth. As each shaft of the pile gets drilled down, an additional segment is again coupled with the bolted coupler every time, resulting in a single Screw Anchor that can extend upto hundreds of feet below the surface of the earth. Generally, Screw Anchors are themselves capable of strengthening the foundation, but sometimes, a concrete foundation is also incorporated to enhance the strength further.

When to use Screw Anchors

Screw Anchors utilized in residential as well as commercial applications. They are used to support and strengthen the foundation of the structure. They can also be used to repair the damaged foundation. Screw Anchors suited in the adverse soil conditions where conventional foundation systems fail to perform. Below are the 

circumstances in which Screw Anchors can prove to be extremely useful. 

● To repair the damage and cracks produced on the interior walls.

● To get an uneven floor repaired

● To repair the damage and gaps produced in the doors and window frames. 

● To repair and remove the disturbance produced while opening and closing the door.

● To repair the cracks and splits formed in basement walls.

The most significant advantage of using Screw Anchors for repair works is that the repair work is of short duration, and minimal disturbance occurs in the day to day operation.

Advantages of using Screw Anchors

There are numerous advantages of using Screw Anchors over conventional foundation system:

No Excavation

Screw Anchors don’t require excavation for its installation, thereby reducing the overall time and cost needed for the project. Since excavation is not necessary for its installation; therefore, the damage caused to the surroundings is also minimal. It saves the time involved since no cleanup work is needed.

Quick Installation

The most significant advantage of using a Screw Piers is that it offers immediate loading capability. Unlike conventional concrete piles, it doesn’t require time to settle down or dry out. No additional machinery needed for installation, such as a crane or a piece of large drilling equipment. Also, the loading capabilities increased by coupling it with small equipment.

Small Footprint and minimum Vibration

Screw Piles  produce minimum noise during their installation, therefore, and used in the restricted areas. It causes minimal disturbance in the surroundings. 

No time to Settle down

The best thing about the Screw Piers is that they offer immediate loading capability. Unlike conventional concrete foundation systems, they don’t need time to settle down or dry out. With time their loading capacity also increases. The older they become, the better will be their loading capacity.

Environmentally Friendly

Screw Anchors offer an environment-friendly process. They cause the least disturbance to the surrounding. Generally, high quality recycled steel is used by the manufacturer for its fabrication process. To make the fabrication process environment friendly and also reduces the overall carbon footprint.

Installation carried out throughout the year.

Unlike conventional concrete foundation systems, Screw piles don’t need time to settle down or dry; therefore, they are not dependent on the different environmental parameters. Whether it is winter, summer, or rainy season, they can be installed easily in any season.

They are best suited for remote areas.

Screw Piles are best suited for projects located in remote areas. Since no large machinery and equipment needed for their installation, they installed in remote locations where there is no proper transportation facility and areas with steep terrain.
