Micropiles are used in Europe around 1950 to repair existing foundations and underpinning works.
In Singapore, using of bored micro piles as building foundation is getting popular for re-development of conservation buildings, A&A works and even for new developments.
The installation of micropile is similar to bored pile. However, the micropile uses site grout-mix instead of ready-mix concrete
The small hydraulic drilling machine can be used to install micropile. Apart from light and small machine, the supporting equipment such as grout mixer and pump are very compact and suitable for sites with space and height constraints.
