DYWIDAG Multi-bar Micropile System

The perfect foundation element for higher loads.

The DYWIDAG Multi-Bar Micropile system is similar to the Micropile system, but uses multiple bars inserted into a single borehole. Suitable for any soil type, the multi-bar assembly is an efficient system for handling large loads, with a quick and simple installation procedure. It is particularly suited to low headroom applications or where piles are located adjacent to existing structures thanks to the compact design.

  • Compact, lightweight drilling equipment allows for pile installation even in areas with low headroom 

  • Vibration-free drilling prevents damage to adjacent structures, so drill holes can be placed close to existing walls or structures whilst keeping disruption to a minimum

  • Short bar sections with couplers can be utilized in low headroom locations 

  • Continuous, robust thread allows for rough site handling and for easy on-site length adjustments since cutting or coupling of the rod is possible along its entire length
