Micropiles<\/h2><\/div>

Micropiles are piles with a diameter of up to 300 mm, designed to transfer structural loads primarily through shaft friction along the soil\u2013pile interface.<\/strong><\/h3><\/div>

At Soletanche, micropiles are installed using two drilling technologies. Drilling with specialized hollow threaded drill rods fitted with a drill bit, combined with simultaneous grout injection. The grout facilitates drilling and ensures effective bonding between the rods and the surrounding soil. Drilling within a temporary casing, combined with simultaneous grout injection, installation of reinforcement, and subsequent grouting\/injection.<\/p>\n<\/div>

Advantages of micropile technology<\/h2><\/h3><\/div>
    \n
  • Versatile application \u2013 suitable for foundation works, tension load transfer, inclined drilling, repairs, strengthening works, and retaining structures.<\/li>\n
  • Flexibility in challenging site conditions \u2013 effective in restricted headroom, platform-based operations, and in close proximity to existing structures.<\/li>\n
  • Adaptability to soil conditions \u2013 installation methods are selected based on soil stability, drillability, hardness, and grain size distribution.<\/li>\n
  • Wide range of diameters, lengths, and installation methods enables tailoring micropile parameters to the specific requirements of each project.<\/li>\n<\/ul>\n<\/div>

      \n
    • The use of low-carbon concrete certified under the Soletanche EXEGY<\/strong> label significantly reduces the carbon footprint of projects, allowing CO\u2082 emissions to be reduced by up to 40% compared to conventional concrete.<\/li>\n
    • Additionally, project optimization<\/strong> carried out by Soletanche design offices enables a reduction in material consumption, for example through alternative solutions such as unreinforced diaphragm walls, further minimizing environmental impact.<\/li>\n<\/ul>\n<\/div>
