– Pilot drilling (performed according to the project and the marked line)
– reamering (extension) of the drill tunnel to the required dimension (in heavy soils such as limestone, sandstone ect, several ereamering must be made to achieve the final diameter of the tunnel)
The entire drilling process can be monitored by a computer and the measuring system provides continuous information on the mobility of the drill rod.
Eesti Horisontaalpuur OÜ owns several different directional drilling machines. The 15N drilling machine drills from soft soil to moraine soil. The 18ACS can drill on both soft and heavy surfaces, including granite. The Prime Drill is used for drilling large diameters and longer lines.
