Our Eccentric Casing System (ODEX) is a cutting-edge drilling tool designed for water well drilling, anchoring, and micro piling projects. It efficiently drills holes while protecting them from caving in, reducing drilling time significantly. The ODEX system is ideal for anchoring projects, ensuring slope reinforcement requirements are met effectively. In soil, clay, and sand rock formations, the ODEX system proves to be the most economic and fastest solution for protecting holes from collapsing with permanent or temporary casing tubes.
