What is directional drilling

You may be wondering what directional drilling is. This is a method that is applied by technicians when locating pipes for utilities. All they have to do is drill the ground in a horizontal position and as this is being done by you, they do not have to disrupt landscaping. This is a better way of doing it for initially, technicians had to dig across an expanse of soil to install pipes. This would normally take a while, stretching to weeks and also required a lot of manpower to do trenching for pipes. It’s no doubt things are at a better place now.

The process usually involves a small screw connected to a hollow pipe of a tracked directional boring machine that is launched into the ground at an angle. As the drill gets pushed to the ground, a drilling fluid containing bentonite polymer and water follows. This solution is meant to make the hole stable. The drill then results to underground semicircular arcs and then leaves the ground. To make the hole larger so that it can host pipes, a reamer is sent back through. Finally, the polyethylene pipes are fused together along the lengths, and then they are heated until a seamless connection on the entire length is achieved.

Benefits

Among the advantages of using this system is durability. This is because the pipes are very strong. Another advantage is that the installation becomes much faster without having to disrupt the landscape which is unlike systems of chain trenching Melbourne professionals follow, which have to significantly disrupt the soil. The cost of installation also significantly reduces as a smaller crew will be used. The convenience of being able to install pipes anywhere is another big win for people who will use this system. The system also does not impact the environment, in this case the soil, because the pipe connections are lasting; therefore, soil contamination will be negligible.
