Sonic drilling and vibro technique

Aside from making ground anchors and micropiles, the sonic drilling and vibro technique is especially suitable for:

• Installation of PE-tubes for horizontal soil sealing (as an alternative to underwater concrete);
• Pre-drilling in very hard soil conditions, for example prior to the installation of foundation piles, or vertical drainage strips;
• Destructive drilling in hard rock, concrete, or even steel elements;
• Deep drilling for soil sampling (sonic sampling);
• Installation and removal of casing tubes, for example, thermal remediation, dewatering, measurements, or ground freezing;
• Installation of Tubes a Manchettes (TAMs) for compensation grouting and permeation grouting.

The benefits of the sonic drilling and vibration technique for the items listed above include:

• very limited effect of vibration to surrounding objects due to sonic frequencies.
• high accuracy installation (with little deviation).
• ability to penetrate in very hard soil conditions >20 MPa (sand) or 250 MPa (rock).
• installation speed.
•limited use of energy and additives in comparison to conventional drilling techniques.
