Foundations for Signs: Quick & Reusable Foundations for Signage

Foundations shouldn’t be the hardest part of your signage project. From underground services to tree roots and possible planning issues, it’s sometimes challenging to lay full concrete foundations.

Ground screws, luckily, offer a flexible solution that suits signage foundations brilliantly. 

You can screw them directly into the ground without any excavation, install them in hours rather than days, and relocate them when circumstances change down the line.

This is a game-changer. Think digital displays positioned for optimal viewing, highway signs installed within overnight traffic windows without major disruption, and event signage installed and torn down without leaving any trace on the site.

Read on to learn more about signage foundations and how ground screws fit the brief.

Why Traditional Sign Foundations Create So Many Problems

Traditional signage foundations turn straightforward projects into drawn-out exercises that cost more time and money than they should.

You’re often dealing with excavation permits that take weeks to approve, coordinating truck access through busy streets, and installation schedules that stretch over multiple visits. Each step creates potential delays and disruptions.

Another challenge comes when you can’t simply dig wherever you need to. Underground services, such as gas pipes and electrical cables, require careful location to avoid them. Planning restrictions in conservation areas or near protected buildings add another layer of complexity. Busy urban locations make access difficult and expensive.

Then there’s the mess factor. Traditional foundations mean skips full of excavated soil, concrete mixers blocking access routes, and cure times that leave the site in limbo for days or weeks. For businesses trying to stay operational, the disruption all adds up.

What Are Ground Screws for Signage?

Ground screws work like oversized corkscrews, twisting into the ground to create solid mounting points for any type of signage. 

The helical plates along the shaft cut through different soil layers while compacting the surrounding ground, creating anchor points that resist both the downward weight of your sign and the lateral wind forces. 

Unlike concrete foundations that require excavation work and days of curing time, ground screws bear their full structural load immediately after installation. They’re effective for highway displays, digital advertising, event banners – any signage application that requires secure, reliable mounting.

How Ground Screws Benefit Signage Installation

Ground screws eliminate most of the complications that make signage projects expensive and time-consuming. Here are the key benefits they bring to the table:

1. Minimal Underground Service Risks

The installation process displaces soil using controlled mechanical torque rather than removing it through excavation, which mitigates much of the risk of hitting gas mains, cables, or water pipes.

2. Immediate Load-Bearing Capacity

Ground screws bear their full structural load immediately after installation, so there’s much less waiting around for concrete to cure or worrying about weather conditions affecting the setting process.

3. Complete Installation Flexibility

Ground screws maintain complete flexibility throughout your project lifecycle. If positioning needs adjustment after installation, individual screws can be relocated without rebuilding entire foundation systems. 

4. Simplified Planning Permission

The permitting process becomes much simpler since ground screws typically don’t require excavation permits that can add weeks to approval timescales and substantial costs to project budgets.

Different Types of Signage Applications

Ground screws are effective across all signage categories, but certain applications particularly benefit. Let’s take a look at those now:

Highway and Road Signage 

Highway signs require long-term structural performance, while installation logistics and disruption are at the forefront:

• Traffic management costs that can spiral out of control rapidly
• Road closures that need to be kept as short as possible for safety reasons
• Regulatory requirements that don’t allow for mistakes or extended timescales
• Access limitations that restrict equipment options and delivery logistics

Ground screws are quick and easy to install, using equipment that fits in a standard van. Even complex signage systems can be set up in just a few hours. 

We offer an in-house ground screw stabilising system designed and tested to meet the stringent requirements of public signage installations.

Digital Advertising Displays 

Digital advertising screens aren’t cheap, and their success depends heavily on being positioned correctly. 

Viewers need a clear, head-on angle, and advertisers expect their messages to land with maximum impact. Ground screws offer much-needed freedom and flexibility:

• Pinpoint placement without the friction of heavy trucks or excavation limits
• Fine-tuned adjustments after installation, so you can tweak angles for visibility
• Stable, vibration-free mounting that withstands strong winds

Event and Temporary Signage 

Event signage faces some of the industry’s most demanding installation schedules. Moreover, many events take place on restricted sites. Pouring concrete is simply not an option. 

Ground screws flip the equation, offering strong, adaptable foundations that require minimal excavation work. 

• Quick installation: Signs can be secured in hours, not days
• Certified wind resistance: Stable enough for professional displays
• Complete removability: Pull them out after the event with no damage left behind
• Lightweight logistics: No trucks, blocks, or ballast weights to move around
• Reusable hardware: The same screws can serve across multiple events

Ground screws deliver certified structural performance that meets professional wind-load standards, yet they can be removed entirely once the event is wrapped up. Venues can be easily restored to their original condition right after teardown.

For instance, at the RHS Malvern show, our team installed six commercial-size 76mm x 1600mm ground screws, each one fitted with custom–made brackets designed specifically for their 150mm x 150mm posts. 

We could easily manoeuvre the site, install the screws, and remove them post-event, all with minimal distribution. Read the case study here.

Installation Options For Ground Screws

For smaller projects, self-install systems can work well. However, highway and large commercial signage almost always call for professional installation, with certified performance documentation to satisfy engineers and meet regulations. 

Digital displays also benefit from expert installation, not only because precise positioning is critical for visibility, but also to protect sensitive electronic equipment.

Other examples of when you might need to rope in professional help include:

• Directional signs and wayfinding systems at events and festivals
• Marketing boards and promotional displays 
• Commercial signs with heavy or expensive digital displays

The most important factor for long-term reliability is whether the chosen specification matches the expected loads and ground conditions. Professional installation delivers that assurance. We can also provide load testing, vital for signage exposed to strong winds or subject to regulations. 

Ground Screws Deliver for Signage Projects

Ground screws remove the usual constraints that make signage installation expensive, slow, and unpredictable. 

Their portable, flexible nature accelerates timelines, reduces costs, and improves logistics. At the same time, they offer long-term flexibility – foundations that can be adapted, relocated, or reused as requirements change throughout the project’s lifespan. 

It doesn’t matter if you’re handling highway signage, a digital display, or some type of commercial property signage – ground screws deliver where concrete can’t.
