Choosing the Right Ground Anchor for Your Terrain and Load
Step 1 – Know Your Ground Type & Load Requirements
Start by identifying your soil type and the load your anchor needs to handle. GroundGrabba offers a solution for nearly every terrain and application—from recreational camping to serious commercial use.
| # | Terrain Type | Anchor Recommendation | Load Class |
|---|---|---|---|
| 1 | Sand, beach, dunes | GroundGrabba Lite (recreational only), Pro I, Pro II, Commercial Pro I, Commercial Pro II | Low to High |
| 2 | Clay (compact, sticky) | All GroundGrabbas (GR13 & GR14) depending on load | Low to High |
| 3 | Rocky / Hard soil |
Junior, Pro, Pro I, Commercial Pro, Commercial Pro I *Pilot hole may be required |
Low to Medium |
| 4 | Grass-covered / mixed soil | All Steel GroundGrabbas (GR13 & GR14) | Load dependent |
| 5 | Similar to #3 – shallow hard-packed soils | Same as above | Low to Medium |
| 6 | Soft topsoil (mud, grass, wet loam) | Pro I, Pro II, Commercial range (load dependent) | Medium to High |
Step 2 – Match the Anchor to the Job
Think about the asset you’re securing and its weight, use, or legal compliance requirements.
| Use Case | Recommended Anchor(s) |
|---|---|
| Camping or tents | Pro, Pro I, or Pro II |
| Site offices / containers | Commercial Pro I, Commercial Pro II, or Threaded GR14 |
| Tiny homes / emergency shelters | Commercial Pro I, Commercial Pro II |
| Dogs / pets | Grounded Paws Kit — add a Pro I for sand |
| Inflatables, stalls, general events | Pro II or Commercial Pro range (substrate dependent) |
| Stretch tents, marquees, large event rigs | Commercial Pro I, Commercial Pro II, with optional ClosedHook 14s |
Step 3 – Choose Your Anchor Length
Generally:
– Use shorter anchors for hard terrain or shallow installs
– Use longer anchors for soft soils or heavier-duty holding
| Anchor | Length | Application |
|---|---|---|
| GroundGrabba Pro | 315mm | General camping, hard ground |
| GroundGrabba Pro I | 465mm | Camping with higher loads, mixed soils, grass-topped sand |
| GroundGrabba Pro II | 615mm | Soft sands, inflatables, medium-duty commercial setups |
| Commercial Pro | 450mm | Clay, compact soils, inflatables, ground mats |
| Commercial Pro I | 600mm | General purpose — towers, inflatables, events |
| Commercial Pro II | 900mm | Extreme hold — tiny homes, soft ground, portables |
| Threaded GR14 Anchors | 450–900mm | Use where anchor hole size is restricted (15–40mm) |
