The Water Jetting Process

Pressurized water is used to loosen and remove soil. A vacuum source makes sure that all the excess water and soil is promptly removed from the site making sure that the underground infrastructure remains intact and clearly exposed. This earth is then stored in our self-contained trucks to be removed.

We are able to locate pipelines, phone lines and fiber optics, in fact anything that may be buried under ground. Our usual digs are 0.8 to 2.2m underground, Our operators are trained, responsible professionals who work safely and efficiently..
