Foundation system Ground Screw anchor Ground Screw Pile for Helical Pile Underpinning
- The Ground Screw Piles can be used for both horizontal and vertical timber applications, e.g.posts or bearers.
- Suits: 70*70mm. 90*90mm. 110*110mm. 120*120mm wooden post.
- 1. Insert the Ground Screw, twisting it until the stirrup base is level with the ground, ensure all stirrups are secure and level before constructions.
- 2. Insert timber beam into the U-bracket, leaving a 10-20mm gap.
- 3. Fix beam to U-bracket with one screw, ensure that the beam is level and fasten all remaining screw.
- 4. For permanent fixation it is recomended that a bolt is inserted through the center hole of the U-bracket. All construction must comply with building code and council reulations. Suitable for fencing, gazebos, decking, cubby houses, sheds and carports, NO digging, NO concreting, NO waiting.
The first piece of the helical pile is called the lead; this is the piece that is first rotated into the ground. The lead has multiple helical blades, also referred to as helical bearing plates, that can vary in size, shape, and number. After the lead follows any number of extensions, depending on the required torque or depth. These are simply shafts that are bolted and pinned to the lead and to each other at their ends. The top of the pile is the incorporated into the foundation system via a bracket or other connection method.
Helical Piles are used worldwide to secure residential and commercial buildings, tower foundations, heavy equipment foundations, and many other deep foundation system applications.
The shaft can come in either a circular or a square cross section shape and is typically hollow.

Helical anchor system may be used to reestablish new foundations or restore present ones. Helical foundation anchors are used for lighthouses, roads, railroads, telecommunication, and in a lot of different businesses that need rapid installation or structure near to present constructions. Evidence, maintaining structures, other common places make use of because they are appropriate for compression in addition to tensile loads.
What are Helical Anchors?
A helical anchor is a deep foundation solution which is used in situations when standard solutions cannot be applied to your foundation project. Situations where a foundation may be exposed to moisture for a longer period of time or where the soil conditions are not normal for use, in such a situation a deep foundation solution like a Helical anchor is required

What are the benefits of Helical Anchors?
There are various benefits of using a helical anchor. Some of them are as follows:
It is easy to install and remove
It can be installed easily in any weather condition
It reduces carbon footprints
It has minimum vibration
It reduces foundation costs
It does not require excess soil
The installation process is very clean and tidy as there are no spoils left after installation
What would be the cost of Helical Anchors?
There are various factors involved while deciding the cost of helical anchors. Those factors are:
Location
Type of work
Condition of foundation
Depth of pile installation
How To Install Helical Anchors?
Helical anchors are installed before pouring the foundation or the soil foundation has been damaged
Helical anchors are screwed into the soil and depending upon the location they are attached to the pre-existing foundation with brackets or screws. After the helical anchors are installed the foundation is safe and is ready to combat any future damage due to compression and tension.
How many Helical Anchors are required ?
The number of helical anchors that you require depends upon the following factors:
Recommended distance between the piles
The type of structure
What is the purpose of Helical Anchors
The main purpose of a helical anchor is to transfer the structural load to the soil. There are various other applications also like tension, compression, and lateral load where helical anchors are used.
How to use Helical Anchors?
Drive the helical anchors into the soil up to the predetermined load capacity.
Space the helical anchors at predetermined intervals to share the weight of the structure.
For foundation repair works, attach the brackets to the base of the wall so that the weight is transferred to the anchor.
Install to a height below the ground level where they meet the required torque.
