• Project Name: MICRO PILING

Micro-piles also is known as pin piles, needle piles or root piles are deep foundations that are moulded on the spot and are composed of sand and cement mortar and thoroughly reinforced throughout its length. Micro-piles are employed in the highly compact or consistent ground or in the ground where bedrock or rocky formations are found, in which excavating may only take place with the use of rotating hydraulic drills. They may be placed in an inclined position. A micro-pile casing generally has a diameter in the range of 3” to 12” and allowable compressive strength of 500 tons and more can be been achieved.

*Micro-piles improve bearing capaciAll Projectsty, but can also be constructed for tension and for a limited amount of bending.

*The pile integrates completely with the soil.

*In a single step, the piles are drilled, grouted and injected using the hollow bars as drill rods and grouting ducts along with disposable special drill bits and rotary drilling methods. These drill bits have jet openings which allow for pressure grout penetration while drilling process is carried out into the soil.

*Micro-piles are well suited for use in close proximity to existing structures.

*Micro-piles are ideal for retrofit applications in that they can easily be installed through a core drilled hole in an existing foundation or footing and anchored to the existing foundation for load transfer.
