Drilling methods

Using the HDD (Horizontal Directional Boring machine), we are able to drill underground routes for conduits without having to excavate the ground surface. This is suitable for placing conduits with communication cables, telephone cables, gas pipes, plumbing pipes, and pipelines that cross rivers, as these tasks require detailed surveys on the area that is planned to be drilled and underground spaces using the GPR (Ground Penetrating Radar) beforehand to find underground obstacles. Afterwards, the location where the machines will be installed shall be determined. Generally, HDD machines must be installed spaced from each other, and its drilling position must be thoughtfully considered to suit the depth of the pressure well. While drilling, F5 and transmitter machines will also be used to measure the drilling depth, which can be as deep as 30 meters.
