Micropiles are reinforced structural elements which offer significant benefits for the consolidation of buildings, slopes and excavations.
Micropiling structures are created by placing a metal tube in a hole that has been drilled in the ground. Once the metal reinforcement has been put in place, it is injected with a cement mortar until the hole is completely filled.
These structures are used in civil engineering, for the construction and maintenance of road infrastructure, where they are largely used to consolidate unstable faces, as well as constructing new foundations and to assist with the consolidation of mountains.
The piles have a number of different functions:
- foundations for structures
- containment works for construction excavations
- water barriers
- improving the stability of slopes
In densely built environments, the use of micropiles as a containment structure is very widespread and since there is restricted space for excavations, a wall of micropiles is fitted which allows for vertical excavations, thereby limiting the space occupied by the construction site’s footprint.
