IMPORTANT***Please note that these figures are a guide only.  The results are absolute 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.

We were asked if our 450mm GR14US will have the same or greater hold down ability as a 900mm spike stake. The simple answer is YES. The more in-depth answer is YES IF the substrate is the same type to the full depth of the ground anchor.

In other words if for example the top 300mm of the ground is loose soil and the next is medium density then the lower part is extremely hard, then the 900mm spike will be held by the hardest of grounds and the 450mm is held by soft and medium density only.    Whereas, if it was all sand or all clay then the GR14US (450mm) will surpass the 900mm spike by around a factor of  X1.5. 

Now if we compare same length spike stake to a GR14 of the same length and girth, then the difference ranges from around X3 to X6!
