Dave WB3DWE - In my opinion the trench would be ok, but I'll leave that to the experts on the group. However, I remember chiseling through the caliche to be annoying, but not that difficult with the right tools. It can be done with a "shooter" style shovel, but that is a bit more effort. However, I doubt if you would ever get a copper rod driven through without some major damage to the rod. If the soil is permiable to water, you could try another of my hack methods. Sweat a garden hose connection onto a piece of copper tubing. Attach a garden hose to the fitting, and point the rod down in the place you want to sink int. Then let it rip. In my area, we have a few inches of topsoil, than a really hard clay, then rocky clay, followed by sandy clay/sand. It will even move some rocks out of the way. The tubing becomes the ground rod of course. - 73 de Mike N3LI - Water worked ok for me and I replaced the Steel pipe I used with a clad ground rod after I made the "hole". Now on the job I see electricians using a neat tool. I think Milwaukee makes it. It attaches to the rod and hangs off the side and appears to be able to be clamped on anywhere and hammers it into the ground. Seems to work very well under different conditions. Try rental houses first. If ya belong to a club it would be a good club buy. Dan, N9JBF |

I had to dig a hole with a shovel down to the caliche, then use a heavy hammer and long chisel to get through the caliche. Then, backfill and proceed as normal. Don't know what your configuration would be. Good luck. Thanks Wayne. As a last resort I will hack a trench with a pick and lay in the rod at a shallow angle to the surface.

Dave WB3DWE Not familiar with that soil, but what would happen if you soaked the ground with water? Would it soften it and/or make a mud that you could sink the rod into? I do that around nere in the NC clay and it works pretty well---unless you hit ROCKS. And that is pretty likely, too. 73 J |
