![]() Dave Lemper wrote in message ... The soil in central Texas is called Caliche with a lot of clay, CaCO3 & shale. Attempting to drive in a ground rod yielded only a mushroom on top & blisters on me. Local tool rental place has concrete bits, but maximum length of 18 inches. Possibly longer bits are available in a larger city. Renting a back hoe is out. Any suggestions appreciated. Dave WB3DWE - I lived for many years in the Dallas area. The caliche was down about 2 feet and was about a foot thick. 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. |
