Some drilling methods are especially developed for certain types of soil and may be less, or not at all, suitable for other materials. A project of pipeline and cable construction thus often means that drilling will be done through different soil materials. <br \/>All drilling jobs in soil have that in common that the drilled hole must be stabilized to avoid collapse. Therefore, the drilling process includes the installation of a casing. When drilling is completed, this casing can be used as a conduit. The line (water, power cable, fiber cable etc.) is placed within the conduit pipe. In some projects, and using certain methods, the media may be installed directly in the ground without a conduit pipe.<br \/>Basic information on the most common methods can be found here on our website.\u00a0<\/p>\n<\/div>\n<ul>\n<li>\n<p>        <img decoding=\"async\" src=\"\/wp-content\/uploads\/2020\/03\/Jordraket_text4.jpg\" alt=\"\"><\/p>\n<h3>Impact moling<\/h3>\n<div>\n<p>The easiest and cheapest of drilling methods.

Some drilling methods are especially developed for certain types of soil and may be less, or not at all, suitable for other materials. A project of pipeline and cable construction thus often means that drilling will be done through different soil materials. <br \\\/>All drilling jobs in soil have that in common that the drilled hole must be stabilized to avoid collapse. Therefore, the drilling process includes the installation of a casing. When drilling is completed, this casing can be used as a conduit. The line (water, power cable, fiber cable etc.) is placed within the conduit pipe.
