Ground Anchoring for Roadside Signage, Safety Barriers & Civil Construction Projects

For roadworks, traffic control, and safety, reliable ground anchoring is essential. Sandbags and rebar often fail in soft or unstable terrain. GroundGrabba screw-in anchors provide a faster, stronger, reusable solution for securing signs, barriers, and temporary setups.

Driven with an impact wrench, they dig deep into sand, clay, or firm ground—holding strong where others can’t.

Pro Packs

Perfect for small to medium signage and lightweight infrastructure, the Pro is a 315mm screw-in anchor designed for firm ground. Ideal for situations where speed and simplicity matter, like event detours or pop-up signs on compacted surfaces.

Pro I Packs

At 465mm long, the Pro I provides deeper penetration and extra strength for more demanding applications such as mesh fencing, light barriers, or roadwork signs in variable terrain.

Pro II packs

For serious anchoring in soft or loose soils like road verge sand or recent excavation zones, the 615mm Pro II provides maximum hold. These are ideal for high-wind exposure or where heavier loads need to be secured.

Hook Washer

Used with GR13-series Pro anchors, the Hook Washer prevents hex collars from slipping through oversized base plate holes. Perfect for quickly clamping signs or light bollards where base holes are pre-drilled larger than 26mm.

From the founder:

Hi, I’m David Levine, inventor of GroundGrabba. In 2017, Susu and I set out to create purpose-built ground anchors. Today, our range secures everything from tents to tiny homes. We back our steel anchors with a Lifetime Replacement Warranty* and a 100% RISK-FREE 12-month return policy. Whatever you need to anchor, we’ll keep you grounded.

Multi L Bracket

This adaptable steel bracket allows for bolting over anchor heads to secure timber or metal base plates. Useful for fixing base rails or feet of roadside signs or temporary fencing to your GroundGrabba system.

Ground Anchoring Solutions for Roadside Signage, Safety Barriers & Traffic Control

Whether you’re managing temporary traffic flow, setting up construction signage, or establishing barriers on a roadside job site, anchoring is critical. Unstable signage or shifting barriers not only risk compliance breaches — they can pose real danger to motorists, pedestrians, and workers.

                   

GroundGrabba offers a robust, reusable anchoring solution that outperforms traditional sandbags, star pickets, or rebar. Our screw-in ground anchors are designed for fast deployment and even faster removal, providing the strength and stability needed to secure equipment, signage, and fencing across varied ground conditions.

Engineered to Hold When It Matters Most

In the road construction and civil works industries, conditions vary from asphalt shoulders and gravel lay-bys to clay or sandy work zones. Many traditional anchoring methods struggle in these scenarios — especially on soft or uneven terrain. GroundGrabba anchors solve this problem with aggressive flighted shafts that bite deep into the substrate, creating superior resistance to pull-out, lift, or lateral movement.

Our range of Pro Series and Commercial Series anchors can be driven in using a handheld cordless impact wrench — no need for sledgehammers or heavy machinery. This makes them ideal for mobile crews, government contractors, signage companies, and traffic management operators who need a secure hold without slow or cumbersome processes.

Fast, Safe Setup with Confidence

Imagine setting up temporary signage before peak-hour roadworks. You need the signs to be in place, stay upright in gusty conditions, and not become a hazard. GroundGrabba Pro I or Pro II anchors are ideal for these medium-load situations. Their flighted steel shafts twist into compact or semi-loose ground to provide strong resistance, making them a safe and stable choice for small to mid-sized signage and barriers.

For heavier loads, critical infrastructure, or exposed roadside locations, the Commercial Pro I and Commercial Pro II deliver unmatched anchoring depth and strength. Their thicker 15mm shafts and extended lengths are designed to secure large frames, barrier fencing, and heavy-duty signage — even in stormy weather or high-traffic zones.

Adaptable Hardware Options

GroundGrabba’s system doesn’t just stop with anchors. We provide a suite of hardware to improve adaptability on-site.

Our Hook Washers and Hook Washer 14s are not anchoring points themselves, but function as oversized washers to prevent the anchor’s hex collar from slipping through large holes in timber or steel baseplates. With 26mm and 41mm flange compatibility respectively, they’re designed to suit both GR13 and GR14 GroundGrabba ranges.

Need lateral or vertical fixing options? The Multi L Bracket makes it easy to anchor fences, posts, and temporary traffic structures using multiple orientations. It’s a perfect solution for irregular applications where direct ground-to-frame connections are impractical.

No More Wasted Time or Money

Unlike concrete footings or single-use pegs, GroundGrabba anchors are completely reusable. When it’s time to pack down, simply reverse your drill to extract them cleanly. This saves time, money, and effort — especially for recurring deployments across different worksites.

Many clients across traffic control, civil construction, and local councils now carry GroundGrabba anchors as part of their standard kit — ready for whatever the day throws at them. And with no rust-prone chain or fabric to replace (unlike sandbags), they’re built to last.

Built for Australian Conditions

Every GroundGrabba product is Australian-designed and tested in real-world terrain. Whether it’s a windy coastline, dry inland clay, or shifting roadside verge, these anchors deliver grip you can rely on. They're more than just ground screws — they're a smarter anchoring solution for high-stakes environments.
