The Eccentric Casing System (ODEX) is the primary drilling tool used in water well projects. It ensures continuous drilling while protecting the hole from caving in. This system significantly reduces drilling time, especially when dealing with overburden.
When it comes to reinforcing slopes in anchoring projects, the Eccentric Casing System (ODEX) meets all the requirements. Its design allows for efficient and effective anchoring, ensuring the stability of the slope.
In soil, clay, and sand rock formations, the Eccentric Casing System (ODEX) proves to be the most economical and fastest solution for protecting the hole from collapsing. It utilizes permanent or temporary casing tubes to ensure the integrity of the hole.
