Solitary M-Wall
Ring Bit System

Casing size 219–1 220 mm

Solitary M-Wall ring bit system is used to drill straight interlocked casings through boulders and rock layers even into inclined bedrock. M-Wall is a perfect solution to replace sheet piles and slurry walls in rocky ground conditions.

The solitary design means that the casing shoe and the ring bit are separated which, in the hands of an experienced driller, is a very cost effective drilling solution.


Main applications

The system is available from 219 to 1 220 mm casings and for all major shank designs. It uses Spiral Flush technology, offering class-leading safety in overburden drilling.

Use with
M-Wall retaining walls

M-Wall ring bit system is a tool used to create M-Wall pipe-pile retaining walls. They can do duty as a load-bearing foundation, rather than just a wall that prevents ground masses from collapsing and they can also be made watertight and used with variety of interlocks.

Solitary M-Wall system is a very cost-effective solution in situations where the risk of accidentally dropping, and possibly losing, the ring bit is not significant. In other cases, we recommend the integrated M-Wall system.
