We often have to drill rock in order to make sure the pilings are installed properly.  Typically, we drill 5-6′ into the sub-strata ledge rock to make sure all docks will survive any type weather, no matter how rough the conditions become.

Our auger is called a “rock bullet”. We purchased it from a company that supply’s all the utility companies in New England. These drills are made to drill solid granite without a problem. So, our soft coquina rock down here is quick and easy.
