Frequently asked questions
What is a helical pile?
What types of landscape will it work in?
- Tight Spaces: Using a portable hydraulic drill, even tight spaces are an option. A minimum of 18” wide and 5’ high is needed to drill a helical pile.
- Rocky areas? GoliathTech has helical piles with helixes to adapt to almost all soil conditions. A helical pile can advance through gravel, types of weathered bedrock, and cobble. If a rock is in the path of the helical pile, the helix often can move it. If not, the area can be pre-drilled or excavated. In these cases, the helix is then advanced past the obstacle to be able to anchor in undisturbed soil.
- High water table? A helical pile can advance through a water table and anchor into dense soil without a problem. There are specific calculations to determine compression and uplift. Having a certified installer to know how to install to required specifications is critical. All GoliathTech installers are certified and have gone through extensive training to make sure all piles are installed correctly.
- Liquefiable Soil? Yes. GoliathTech Utah works with engineers to identify minimum depth requirements to install piles beneath areas of high potential for liquification. Careful engineering for adequate spacing and design.
- Clay (even blue clay)? The helix on a helical pile provides a calculable uplift. GoliathTech Utah works with geotechnical engineers to install an anchor helical piles beneath the expansive soils. This provides uplift for any soil movement as well as anchoring in buildable soil.
- Slope: Yes. Even when a heavy machine may not be able to access the location, a hand held hydraulic drill may be required to install on a slope. This is an optimal solution when the pile can provide excellent load capacities without eroding large areas of earth.
How large of equipment is used?
Typically, a mini-excavator with tracks as narrow as 39” is used to install residential helical piles. GoliathTech Utah also has a handheld hydraulic drill that can be used indoors or in tight or otherwise inaccessible spaces., GoliathTech Utah primarily uses two types of machines. Kubota KX018-4 and JCB 215T.
Is a helical pile code approved?
Do residential applications need a special inspection?
This is dependent on the jurisdiction. Typically, because the installation with GoliathTech Utah is installed by a certified installer, there is no special inspection. GoliathTech Utah logs data on every pile installed. For permitted projects, this information is logged and given to the inspector. The installation log provided by one of our certified installers has final torque, depth, location, and piles used. This ensures that each pile is installed to the minimum torque/capacity and depth in accordance with project construction documents.
How long have these been around?
Where are GoliathTech Helical Piles manufactured?
GoliathTech manufactures 100% of all its products in a factory in North America.
Can I install them myself?
If you are a certified installer of helical piles, yes. Otherwise, no. Per the International Building Code, helical piles are only to be installed by a certified installer.
How long does it take to install?
A helical pile can take anywhere from 3 minutes to 15 minutes to install depending on soil conditions or depth to reach native or compressive soil.
When does a person pay
Unless otherwise negotiated, projects over $5K will require 50% due prior to installation and the remaining due upon completion. For projects less than 5K, payment is due upon installation completion.
What makes your piles different?
GoliathTech pile heads are equipped with a nut-fastening system. This exclusive anchoring solution allows the structure to be installed directly on the piles, thereby preventing lateral or vertical movement.
- Zero movement
- Superior resistance to wrenching
