Frequently Asked Questions

Q: What is directional drilling, and why is it used?
A: Directional drilling, or horizontal directional drilling (HDD), is a trenchless method for installing underground utilities such as pipelines, conduits, and cables. This is accomplished using a guided drill bit system. It's used to avoid surface disruption, minimize environmental impact, and navigate obstacles.

Q: What are the main benefits of utilizing directional drilling?
A: The main benefits include minimal surface disturbance, reduced environmental impact, faster installation times compared to traditional trenching, and the ability to navigate under obstacles, such as roadways and waterways.

Q: How does directional drilling work?
A: Directional drilling involves drilling a pilot hole along a planned path using a steerable drill head. Upon completion of the pilot hole, the drill path is enlarged using a reaming tool to the desired diameter, after which the utility line is pulled through the enlarged hole.

Q: What types of projects are suitable for directional drilling?
A: Directional drilling is suitable for a wide array of projects, including the installation of water lines, gas pipelines, electrical conduits, fiber optic cables, and sewer lines, especially where open trenching is impractical.

Q: What is hydro excavation, and how does it relate to directional drilling?
A: Hydro excavation is a non-destructive method of excavating using high-pressure water and a vacuum to remove soil. Hydro excavation is often used in conjunction with directional drilling to expose and verify the location of existing underground utilities, helping to prevent damage during drilling operations. Devco Development and Engineering Directional Drilling and Hydro Excavation, for instance, offers hydro excavation.

Q: How do I choose the right directional drilling company?
A: Choose a company with a proven track record, experienced team, the appropriate equipment for your project, a commitment to safety and environmental responsibility, as well as the ability to effectively communicate throughout the duration of your project.

Q: What factors affect the cost of directional drilling?
A: Several aspects impact the cost of directional drilling, including the length and diameter of the bore, the type of soil and ground conditions, the presence of obstacles, the complexity of the project, and the equipment required.

Q: What permits are needed for directional drilling projects in California?
A: Permits are necessary and vary depending on the jurisdiction and type of project. They often involve inspections depending on the particular project. It's important to consult with a professional and the local authorities to secure the appropriate permits before commencing any directional drilling activities.

Q: What types of equipment are used in directional drilling?
A: Directional drilling uses a variety of equipment, including drilling rigs, drill bits, steering systems, mud pumps, reamers, and locating equipment to ensure precision. Support equipment such as hydro excavation trucks can be also utilized.

Q: How long does a typical directional drilling project take?
A: The project duration varies depending on factors like length, ground conditions, and complexity. Smaller projects might take a few days, while larger ones can span several weeks or even months.
