Product Details

Casing advancement systems for Geotechnical DTH hammers

Features:

1. Efficiency and productivity

Simply put, casing advancement systems meet all challenges and keeps both efficiency and productivity high even in the most difficult ground conditions.

2. Highest reliability

Compared to other methods, casing advancement is in most cases the best and most productive alternative, with highest reliability in hole straightness and reliable assurances that targeted depth or bedrock is reached.

3. Better quality

Epiroc casing advancement systems enable contractors to perform their work faster with higher quality and reduced risk. The system adds value whether the mission is to install foundation, support elements or simply case the hole in collapsing formation.

A multitude of applications

Casing advancement systems, are todays preferred method for drilling in difficult ground conditions; boulders and loose formation, and can be used in a wide range of applications. The most common applications are for geothermal water well drilling, mini/micro piling, ground stabilisation and foundation work. Civil engineering contractors working to secure railway embankments from landslides regularly use the systems for slope stabilisation and soil anchoring methods to avoid damage to the track infrastructure. The casing advancement systems are available either as a solitary ring bit or as a ring bit set, and the types of casing can be permanent or retrievable. You can choose between the ODEX, Symmetrix or Elemex systems depending primarly on the drilling conditions on site. ODEX, Symmetrix and Elemex are parts of a total overburden drilling solution from Epiroc and work well in both down-the-hole and tophammer drilling.
