Geotechnical engineering applications were Ryobi G’s flagship services back in 2000. After years of continuous improvement, Ryobi G is now a leader in geotechnical engineering works in Singapore, securing key projects in public and private sectors. 

MICROPILES

Micropiles are considered as one of the deep foundation techniques to transfer load from structure to the competent bearing stratum at deep depth, especially for sites with restrictions attributed to limited workspace and low head room.

Micropiles consist of two (2) typical types according to its installation method, i.e. driven type (e.g. steel beam, pipe or rail, etc.) and bored type (e.g. cast in-situ using rebars and cement grout similar to bored piles except in smaller diameter ranging from 75mm to 300m).

Ryobi G specializes in the construction of bored type of micropiles using C5, C6, C6XP machines.These machines allow continuous drilling with bentonite, water or even cement grout. Ryobi G has the appropriate machines for different situations faced in the piling works. For instance, we counter space constraints with the availability of small-sized machinery that are versatile and able to maneuver in tightly enclosed areas.

History of micropiles works dated back to post World War II for damaged buildings. Today, it is used widely to stabilize old structures especially heritage buildings and increase load capacity of buildings under restricted and sensitive environment. In fact, it is much more economical for contractors to strengthen the foundation than to tear down existing building and construct a new one.

The advantages of micropiles are aplenty. Micropiles are generally smaller, lighter, less impact to the surrounding properties and more economic for special cases as compared to other deep foundation technique. From an environmental standpoint, installation of micropiles through the rigs is low emission with limited vibration and noise disturbance. The general properties of micropile; with good capacity in resisting compressive and lateral loads have also made this technique very popular in deep foundation construction and excavation works.

Micropiling also has a huge range of applications and they are not only limited to the below:
a) Underpinning works
b) Structural and foundation support
c) Supporting new load and retrofitting
d) Pile wall
