DYWIDAG Multi-bar Micropile System
The perfect foundation element for higher loads.
- Uplift Restraint
- Foundation
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
