Digga MM-10K Hydraulic Drivehead for Mini Skid Steers

Ground screws are steel foundation anchors that are installed into the soil using high torque equipment to support structures without concrete. They function similarly to helical piles but are designed for fast installation and immediate load capacity. Ground screws are commonly used for decks, houses, solar arrays, modular buildings, signs, fences, light structures, and many others.

YES!!

• Build immediately– no waiting on concrete to set
• Fast installation– install in minutes with no excavation or curing time
• Lower total cost– reduced labor, equipment, and material costs
• Versatile– performs in a wide range of soil conditions and climates (including winter)
• Environmentally friendly– lower carbon footprint with minimal site disturbance
• Removable & reusable– ideal for temporary or relocatable structures
• Code-compliant– evaluated under ICC-ESR-4226, helping streamline permitting
  
  

AGS ground screws are widely accepted because they are evaluated under ICC-ESR-4226 for compliance with International Building Code requirements. Final approval is determined by the local building department and project engineer based on soil conditions and project loads.

Yes, ground screws perform well in cold climates when at least two thirds (2/3) of the thread is installed below frost depth. Because they are embedded deep into the soil, they are commonly used in northern regions where frost heave is a concern. Proper design and embedment depth ensure stability.

The load capacity of a ground screw depends on soil conditions and the ground screw diameter. In many soils, individual screws can support thousands of pounds of axial load when properly engineered. Load capacities are listed in Table 5, Page 13 of the ICC-ESR-4226.

Yes, ground screws can often be installed in rocky soil, but some sites require pre-drilling or obstruction removal. Installers may use rock augers or drilling tools to penetrate dense or rocky layers before installing the screw. Review our installation instructions for details.

Our ground screws are hot-dip galvanized steel designed to resist corrosion for decades. Actual service life depends on soil conditions and coating thickness, but properly specified ground screws are designed for long-term structural use. AGS warrantees our ground screws for 25 years, and life expectancy is 50+ years.

Yes, one advantage of ground screws is that they can often be removed and reused. This makes them a popular foundation option for temporary structures, modular buildings, and projects where minimal environmental impact is important.

Yes. Call 811 from anywhere in the country several days prior to installing your ground screws and your call will automatically be routed to your local one call center. Utility companies that have potential facilities in the area of your installation site will be notified of your intent to dig. Each affected utility company will send a locator to mark the approximate location of your underground utility lines. This typically occurs within 2-3 working days. It is recommended you install ground screws at least 18 inches from either side of marked lines.

· Ground screws require low-speed, high-torque drivers(handheld electric or hydraulic units for skid steers, mini skids, or excavators)

· DIY-friendly– many homeowners and contractors rent installation equipment from AGS or our distributors

· Engineered projects require proper equipment to ensure correct depth, alignment, and performance

In many cases, yes, a permit is required for any permanent structure, regardless of whether it’s supported by concrete or ground screws. Requirements vary by jurisdiction, project type, and load conditions.

AGS ground screws are evaluated under ICC-ESR-4226, which helps streamline the approval process with many building officials. In some smaller or non-structural applications, permits may not be required, but it’s always best to confirm with your local building department.

There are several factors that impact the installation time of ground screws, including diameter, length, soil type and the installation equipment you are using. In most cases, they can be installed and ready to load in less than 10 minutes.

AGS ground screws have a significantly lower environmental impact than traditional concrete foundations. Installation requires no excavation, no curing time, and no water, which minimizes site disturbance, noise, and mess. Because there’s no concrete, you also avoid the high carbon emissions associated with cement production.

Ground screws are removable and reusable, making them ideal for temporary or relocatable structures and reducing long-term site impact. The surrounding soil remains largely undisturbed, helping preserve natural drainage and root systems
