How They Work

How They Work

This is currently our mid-range Commercial product. Our industrial-grade GR14 earth anchor range works by penetrating the ground and forming an inverted conical shape of compacted earth for superior grip.

If exposed to extreme lifting forces, unlike fully threaded anchors that can fail catastrophically, our auger-based GroundGrabbas tend to fail in a more controlled manner—often giving warning. The helical flights must

Grabbing Power

Hold Down Capacity 

In our tests, we have found that if we compare same length spike stake to a GR14 of the same length and girth, then the difference ranges from around X3 to X7 in holding power! 

See the complete test chart here

GroundGrabba Commercial PRO I (GR14UM). These are vertical load tests

IMPORTANT***Please note that these figures are a guide only.  The results are vertical lift absolute momentary peak readings and you should allow a decent safety margin.   Ground types vary. Through the depth of one ground anchor the ground can be of different densities therefore different anchoring characteristics.    These all rely on correct deployment.

Recommendations

Recommended Tools to hire or own to help with installation: 

NB. These models were available at the time of writing.

For driving these into the ground, we recommend a high-torque impact wrench. Consider models like:

For driving these into the ground, we recommend a high-torque impact wrench. Consider models like:

  • Makita 40v TW001GZ-40v Brushless 3/4" Impact Wrench.
  • Milwaukee M18 FUEL 2867-20
  • Use a masonry drill at least the same length as the GR14 you choose for pilot holes in harder ground.

Important Note:

GroundGrabba Commercial range is designed for heavy-duty use with a tradie quality heavy-duty impact wrench.

Please note that these are not toys. Ensure you have a powerful drill, especially for hard ground conditions.

Uses & Benefits

The Anchor That Hits the Sweet Spot for Commercial Fixings

Need more grip than a short anchor—but don’t need full cyclone-rated depth? The 600mm GroundGrabba Commercial Pro I is engineered to deliver dependable hold for portable buildings, site sheds, fencing, and semi-permanent structures—without going overboard on depth, weight, or install time.

Secure More, Without the Overkill

This mid-length GR14 anchor is ideal for most ground types including sand, clay, and compacted soil. With a 15mm shaft, 40mm flights, and hot-dip galvanising, it’s built for years of service in tough environments—yet fast to deploy and easy to extract. Use a 1" AF socket and impact wrench to drive it deep in seconds.

Reliable Hold in All Conditions

From event infrastructure to relocatable structures and outdoor storage, the 600mm Pro I gives you the best of both worlds: easier handling than the 900mm model, but enough bite for high-wind zones, uneven terrain, or semi-permanent installs.

Ideal Applications

  • Portable buildings and site offices ("dongas")
  • Relocatable tiny homes and cabins
  • Shipping containers (with stabilised base)
  • Solar panel arrays (non-cyclone zones)
  • Temporary sheds, fencing, and modular structures
  • Event gear, scaffolding, and stabilised shelters

The GroundGrabba Advantage

  • Fast install – No concrete, no digging, no curing
  • Hot-dip galvanised – Long-term corrosion resistance
  • Heavy-duty 15mm shaft – Designed for torque and stability
  • Reusable – Easy to extract and reinstall at new sites
  • Lifetime replacement warranty – Built for the long haul

Most effective & best value for cash on all of The Googles

I have 12 of these holding down a marquee with the sail area of a footy field. They're the best anchors I could find anywhere - the only anchors I tried that didn't bend, move or pull out. And a great price for the job they do. Most effective and best value for cash on the market. And from a small local business too. An amazing job well done. Cheers.

Hi Ken, thank you so much for your wonderful review! We are thrilled to hear that our Commercial Pack has been the most effective and best value for your marquee stretch tent. Our team takes pride in providing high-quality products and we are glad that they were able to meet your needs. Thank you for supporting our small local business, we truly appreciate it.

David and the team @ GroundGrabba
