THE DRILLER'S CHOICE

M-Wall Ring-Bit Systems

Solitary M-Wall ring-bit systems are used to drill straight, interlocked casings through boulders, rock layers, or inclined bedrock.

With this technique, it’s possible to build interlocked casing walls, roofs, and other structures for the construction industry. M-Wall piles can also replace sheet piles and slurry walls in rocky ground conditions.

The heavy duty ring-bit is not attached to the casing shoe, making it the most economical of the ring-bit solutions.

Primary applications:
  • M-Wall pipe-pile walls
  • M-wall pipe-pile roofs
  • Cofferdams
  • Retaining walls
  • Water-tight cut-off walls
