    In a location where rock is present, some authorities will allow you to avoid the cost of a deeper excavation for your conduit runs. Some reductions are 4 for every 2 of concrete cover. In some instances the concrete must be dyed a red color for identification. Sometimes a maximum depth reduction of 12 will be allowed with a minimum concrete cover of 6.
