Micropiles

Micropile is a pile which acts as a supporting structure to transfer the load from the building to the ground. As the name implies, micropiles are small diameter piles constructed by drilling process and are often keyed into rock. There is various diameter of micropiles found in the market ranging from 100mm to 300mm. A micropile is constructed by drilling a borehole, placing reinforcement, and grouting the hole. Micropiles can withstand axial and/or lateral loads, and may be considered a substitute for conventional piles or as one component in a composite soil/pile mass, depending upon the design concept employed.

Micropiles are installed by methods that cause minimal disturbance to adjacent structures, soil, and the environment. They can be installed in access- restrictive environments and in all soil types and ground conditions. Advantages of micropiles are high carrying capacity, less site constraint problems and self sustained operation. Apart from the light and compact drilling rigs, other ancillary equipment like grout mixer and grout pump is very compact in size. Of late, technological advancement in machinery has made it possible for micropiles of much greater diameters to be constructed. Micropiles are widely used in housing area, school, hospital or any location which doesn’t allow making noise during pile driving process.
