MICROPILES

Micropiles are steel foundation supports with a diameter ranging between 90 and 300 mm; micropiles are suitable for all types of soils. These special foundation elements are used in a variety of situations:

  • - consolidation/underpinning of foundations affecting the bearing capacity of a structure;
  • - rehabilitation and/or repair of foundations damaged by external physical/chemical agents;
  • - consolidation of soils before shallow foundations are laid;
  • - installation of anchor piles and tie-rods
  • Micropiles are installed in three steps:
  • - A hole is drilled by means of down-the-hole hammers, tricone bits, spiral bits, etc. .
  • - Then a metal reinforcement is placed (metal tube/cage),
  • - Grouting with water, cement and/or bentonite.

An application similar to micropiles soldier pile walls consist of a series of micropiles placed in a straight line. Soldier pile walls are commonly used as temporary or permanent retaining walls for excavations in urban areas as they prevent noise pollution and soil vibration and do not involve the use of bentonite to grout the hole.
