Horizontal Directional Drilling/(HDD)

is a minimal impact trenchless method of installing underground utilities, such as pipe, conduit, or cables, in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig. Directional Boring/HDD offers significant environmental advantages over traditional cut and cover pipeline/utility installations. The technique is routinely used when conventional trenching or excavating is not practical or when minimal surface disturbance is required. Directional Boring/HDD can be utilized with various pipe materials such as PVC, polyethylene, polypropylene, ductile iron, and steel.

DSI has the equipment and team to fulfill all your project’s drilling requirements.

Utility Line

DSI has the experience and the ability to handle the placement of both mainline and service lines for phones, internet, cable, power, sewer, water, gas or irrigation on any project. Combined with the methods of directional drilling, plowing, cable pulling, aerial installation and fiber jetting, we also have the expertise to trench or open cut utility line installations.

Fiber Optic Cable

DSI can place fiber optic cable in a variety of ways to meet your project’s needs.

Cable plowing machinery is a piece of equipment with a single blade which is used to lay buried services fiber optic cable. A coil of the service cable is mounted on the equipment, led down a guide behind the blade and is left buried behind the plow in a single operation, without the need to pre-dig a deep trench and re-fill it. This is also known as direct buried fiber.

Traditional fiber optic pulling machines can be used to pull new cables through a duct. They use a hydraulic motor along with a capstan to allow for pulling cable in long distances with variable control and speed.

Fiber jetting/blowing is the process of blowing a cable through a duct while simultaneously pushing the cable into the duct. Compressed air is injected at the duct inlet and flows through the duct and along the cable at high speed. This can be done with both conventional fiber optic cable as well as microfiber cable.

Aerial cable installation is an insulated telecommunication line which is suspended between utility poles or electricity pylons. As aerial cables are completely insulated there is no danger of electric shock when touching them and there is no requirement for mounting them with insulators on pylons and poles.
