HOW ARE HELICAL GROUND SCREWS INSTALLED?
Helical ground screws are an innovative alternative to concrete foundations, they also allow for foundation installation in difficult to reach places, or places where traditional concrete foundations cannot be installed. But what is the process for installing ground screws? Here we will explain the process of installation of helical ground screws, so you know what to expect when using ground screws for your project.
What’s the best time for installation?
Ground screws can be installed any time of year, unlike concrete they’re not effected by extremes in temperature or humidity. Allowing for work to be carried out on projects any time of year, no matter the weather or season.
With traditional concrete foundations there a large portion of the work involves preparing the site for the foundations. This usually involves using heavy machinery to dig trenches, having teams on site to prepare any needed formwork. In comparison, ground screws need very little site preparation before installation. Once a site check has been completed to ensure ground screws can be installed on your site then all that is needed is a to simply clear any large rubble from the foundation area and to mark the location of each screw as per your design. The ground does not need to flattened or dug, topsoil does not need to be removed and changes in weather won’t affect the installation on the day, so no need to pump any water from trenches and formwork before commencing the installation.
On the day of installation
On the day of installation you will need a small number of labourers and machinery. Depending on the size of your helical ground screws handheld portable machinery can be used. There are no worries about concrete curing before it can be poured or the weather halting an installation before it is even begun.
Your installation team will arrive and confirm the initial check is correct, once this is completed work can begin.
- A pilot hole is made to guide the Ground Screw into the correct position.
- The ground screw is placed in the pilot hole and then attached to the rig.
- The machine slowly rotates the ground screw as it pushes it into the ground, much like a screw in a wall the helical design removes and feeds the ground up as it is driven in to its recommended depth, creating a strong, load bearing point.
- If your helical ground screws are being driven to a depth beyond their initial length, additional extension poles can be attached.
- The rig is disconnected from the ground screw and the process begins again, until all screws have been installed.
- Our install team will then check and adjust the levels of the ground screws to ensure they’re all level to one another and at the height requested by you.
- Once installed ground screws need no time to settle, so load can be placed on them immediately after installation, allowing. So you can begin installation of your subframe the same day.
There is very little aftercare required, the galvanization on the screws prevents corrosion, the site does not need to be checked to ensure the foundations are free of cracks and no messy formwork needs to be removed and disposed from site. Helical Ground Screws are also easy to remove, making them great for temporary structures such as cabins, light steel frames and even open-air stages for events.
