Directional drilling is a trenchless method of underground pipe installation. Horizontal boring machines drill a pilot hole which is able to enter and exit at predetermined locations and even change direction to avoid underground obstructions and preexisting lines. From this pilot hole, a new sewer, water line, or conduit line can be established without a preexisting line – allowing for completely underground installation without the mess or expense of trenching!
Benefits of Directional Drilling
- Avoid damage to your building, landscaping and hardscaping
- Trenchless option for establishing a new line
- Significant cost savings compared to conventional line installation methods
- Shorter completion times & safer for the environment
How Does It Work?
Establish A Pilot Hole
After the site has been prepped, a horizontal boring machine (about the size of a golf cart) is moved into place and a bore head is connected to hollow pipe which enters the ground at an angle. As the bore head drills a pilot hole, additional pipe sections are added until the pilot hole is complete.
Pilot Hole Enlarged For New Line
After the boring head exists at a predetermined location at the other side of the run, a reamer is attached. Once attached, the reamer is pulled back through the line clearing soil and even rocks to expand the hole to a size that is 25% larger than the pipe that is to be inserted.
New Line Established
Once the hole has been prepared, a new line is pulled through the opening created. Once successfully in place the ends of the line are connected and the project is complete.
Why Choose Directional Boring?
Trenchless Method For Establishing New Lines In the past, the only way to establish a new line was through expensive and damaging trenchwork. With directional boring you can get the advantages of trenchless methods where a preexisting line is either unavailable or needs to be relocated.
Saves Money A significant portion of the cost of a new line goes into digging for a new line and putting back excavated material.Tap into significant cost savings and skip the damage that comes with traditional methods used to establish new lines.
Saves Time Drilling not only saves money, but it also creates a significant time savings. Without trenches to dig or material to put back, the completion time on projects using drilling is significantly less than with conventional methods.
Directional drilling is a method of underground pipe installation without the use of excavation methods. There are several benefits to directional drilling, including the avoidance of damage to your building, landscaping, or hardscaping; it’s a trenchless option for establishing a new line, it offers a significant saving of cost compared to conventional line installation methods, it has a shorter completion time, and it’s safer for the environment.
First, we establish a pilot hole. This happens after the site is prepped. A horizontal boring machine, about the size of a golf cart, is moved into place and a bore head is connected to a hollow pipe. This pipe enters the ground at an angle, and drills a pilot hole. As this bore head drills the hole, additional pipe sections are added until the pilot hole is complete. The pilot hole is enlarged for a new line, expanding it to 25% larger than the pipe that’s to be inserted. The new line is then established, and once the ends of the line are connected, the project is complete.
Not only does this trenchless method save money - thousands of dollars, in fact - it also saves time. Instead of a six-week long project, it’s likely only a few days. It’s easy to complete and much faster.
