Concentric Casing System With BlocksInquiry Now
With Blocks
Drilling through formations with loose, unconsolidated material always comes with problems such as the bore hole caving in or collapsing. How to avoid these problems?

With years of field practice and research, Maxdrill has developed its Concentric casing system with blocks applicable for foundation piling with backfill and pebble formations and casing depth within 40 meters.

(1) diameter: 38mm-130mm.
(2) tooth shape: three cutter alloy teeth, cross alloy teeth, ball tooth thread alloy drill, cross all steel drill, etc

Structural Advantages

♦ Straightness: ensures the straightness of borehole in different topographic and geological conditions.

♦ Adaptability: ensures penetration efficiency in complex topographic and geological conditions, such as gravel and landfill of construction refuse.

♦ Lower torque: the system torque is less than eccentric casing system.

♦ Easy to unlock an re-rock: easy to re-rock after unlock.

♦ Drilling at any angle: concentric casing system can drill under horizontal, vertical and inclined conditions.

♦ Environmental: better than eccentric casing system, because of its advantages of drilling smoothly, small vibration and low noise, it is more suitable for construction in urban areas.
