CONVENTIONAL HORIZONTAL DIRECTIONAL DRILLING PROCEDERE.
CHARACTERISTICS.
▐HDD suitable for binding soil conditions
▐Unsupported bore hole stabilized by bentonite suspension
▐ Bolders/gobbles or sharp stones could damage pipeline
▐ Pipeline has a corrosion protection coating
GEOLOGY
▐During pull-back pipeline / coating has soil contact
▐ Coating damages reduce corrosion protection and lifetime
▐Quality control after finishing pull-back by Cathodic Measurements
