UNUSUAL USES FOR GROUND SCREW FOUNDATIONS

As ground screws become a more commonplace foundation system, we are seeing more and more projects at Red Leaf Ground Screws that use ground screws in a unique way. Their ease of install and removal, with minimal ground disruption makes them a great system for a number of unusual and sometimes temporary projects.

We’ve put together some of the stranger projects that take advantage of ground screw foundations to improve the efficiency and carbon footprint of their projects.

Construction Site Hoarding

You will usually see construction site hoarding on large building projects, where security is needed to ensure tools and machinery left on site cannot be accessed by the public and to ensure no member of the public wanders onto the site risking injury. Site hoardings often also have advertisements on them for the building project and contractor and obscure any unpleasant views of the construction site to local residents.

The construction site in the image to the right was a single building rather than a multi building project, however, the client needed to provide a temporary barrier between their site and the surrounding domestic dwellings to ensure safety of tools and the public. The ground screws took half a morning to install, and the hoarding could be erected as soon as the screws were in the ground. Providing secure hoarding, that can be easily removed after the project is completed, with minimal damage to the site.

The potential for ground screws to be used on larger hoarding projects is huge, as the screws can be reused, it’s possible to use the same screws for hoarding from project to project. They offer more security than hoardings that use weighted blocks and like these blocks, can be reused from site to site.

Retaining Walls

Commercial retaining walls are often secured by steel beams driven into the ground with heavy duty precast concrete panels inserted between the beams. While ground screws may not be suitable for commercial size retaining walls, they can make great secure foundations for smaller retaining walls that are lower loaded and use wood rather than concrete. The image to the left show just such a project, the client required ground screws for their building’s foundation and were also looking for a way to secure their retaining wall with minimum need for heavy equipment. The ground screws were installed to provide foundations for the steal beams that hold the timber in place. The installation took less than a day, with the steels and wood panelling being installed while our team worked on the building foundations.

There’s a number of areas where ground screws can remove the need for heavy equipment on site, making them a great alternative on sites where access for heavy plant is difficult but a strong, secure foundation is needed.

Temporary Stages

There are many events throughout the country that require the set-up of a temporary stage, some for short periods of time, such as weekend festival and some for a number of weeks or months during a special event. Ground screws are quick to install and remove, along with being strong and secure, this makes them a good choice for staging on sloped surfaces and out on grass and soil where foundations are needed to stop the stage subsidence.

The image to the right shows a temporary stage at Charleston House that is secured to the concrete yard by ground screws. The architects on the project were looking to make the project as sustainable as possible, with the stage being made of wood they were looking for a foundation system that was more sustainable than traditional concrete. Unfortunately, the concrete yard site for the stage is sloped, making it difficult to install a level stage. Drilling through the concrete of the yard, ground screws were then driven into the soil below, providing a secure level foundation. When the stage is ready to be removed, these holes can be backfilled with soil and concrete to restore the site back to the same state as before the stage was installed.

Large Model Displays & Art Installations

Large model displays are generally seen at places such as zoos and theme parks, displaying life size animal figures or false fronted buildings or decorations. Ground screws make a great foundation for these projects, they have a low visibility when installed, making it easy to cover with a few plants or in long grass and the lack of damage to the site during installation and removal means there’s less work required to ensure the site is visually appealing to visitors. Ground screws also make great foundations for art installations, their strength provides a secure foundation that doesn’t subside, and their quick and simple install and removal causes minimal damage to the site.

The image below shows a ground screw installation holding a number of large-scale dinosaur models, the weight of these models is not an issue for ground screws and it’s clear that there’s little ‘set dressing’ for the client to hide the ground screw heads. These dinosaurs can be quickly and easily moved or rearranged if needed, and when it comes time for the display to be replaced the removal of the ground screws will leave minimal damage to the site, making it easier for a new display to be installed.

Other unusual uses

As you can see from the examples above, there are a number of unusual uses for ground screws alongside their use as an alternative to traditional concrete foundations for building projects. Ground screws, unlike concrete pads, are a very flexible system, the lack of excavation and ease of installation make installing foundations for these unique projects much easier and cost effective. It’s also possible to change the locations of screws if needed before installation, without the need for additional excavation or shuttering that a concrete pad would require.
