Applications

1. Water well drilling

The Eccentric casing system (ODEX) is indispensable in water well drilling projects, offering simultaneous drilling and protection against caving. This results in a significant reduction in drilling time, especially in overburden scenarios.

2. Anchoring
The Eccentric casing system (ODEX) excels in anchoring projects, particularly for slope reinforcement, ensuring superior stability and strength.

3. Micro piling
Ideal for soil, clay, and sandy rock formations, the eccentric casing system ensures economical and rapid drilling, effectively preventing hole collapse with both permanent and temporary casing tubes.
