The term micropiling is often misunderstood. At Branlow we are keen to promote a greater understanding of minipiling and micropiling technology.
Micropiling : can be defined as small diameter piles, typically less than 150mm, where the pile load is carried structurally predominantly by the pile reinforcement. Hence micropiling is often relatively heavily reinforced with a substantial full length central reinforcement bar. Micropiles are normally grouted due to small volumes. Branlow solutions offer self drill micropiling where a central hollow threaded reinforcement bar acts as both final reinforcement in the completed pile and as the drill rod during installation. Branlow selfdrill hollow threadbar micropiling systems are installed with sacrificial drillbits under a grout flush. Dywidag MAI and Ishebeck Titan systems amongst others are available. In granular deposits in particular the impregnation of grout into the surrounding ground significantly enhances the geotechnical capacity of the pile. Mass concrete and rock can also readily be drilled. These piles work well as both tension and compression piles and can be installed on a rake or inclined angle to provide reticulated pile solutions.
Micropiling Advantages
- Small lightweight equipment
- Low noise and vibration
- Suitable for tension loads
- Minimal site preparation
- Can be installed successfully into most ground conditions including rock
- High output - combined drilling and grouting make high piling outputs possible
- Limited headroom, restricted access capability
