Special applications

Adaptable ductile iron micropile for construction

Saint-Gobain PAM's ductile iron micropile is an industrial product for construction, which can be adapted various to land constraints and building types.
It has a narrow cross-section that is driven or hammered into the ground using an excavator fitted with a standard hydraulic hammer. The micropiles are installed in groups to establish the foundation of a building or to reinforce it.

Our micropiles are used for various types of construction:

  • Rental buildings and residences
  • Industrial buildings and warehouses
  • Hillside underpinning and stabilization
  • Foundations of silos, masts and wind turbines
  • Foundations of bridges
  • Soil reinforcement
  • Invert anchorage
  • Pipeline supports



  • Resistance: of ductile iron to pile driving, soil compaction and structural load.
  • Fast and easy assembly/installation: fitted together using specific male and female conical ends; quick and easy driving and trajectory and depth checking; automatic linkage, easy to use, top pile cut off at ground level; no excavated earth or material to be removed after driving; low investment cost; high installation rhythm with up to 500m of piles driven per day; and very little pile cutting required on site while cut-offs can be re-used.
  • Reliability and durability: of foundations with a rigid set of piles that are perfectly fitted together and that last a very long time in the ground.
  • High performance: injection of concrete into the piles increases the performance of the foundation.
  • Perfect solution: for geotechnical requirements, combining friction and point effect to constitute effective and long-lasting ground reinforcement.
  • Flexibility: necessitates only half the time, manpower and excavation/removal required by bored piles and ideal for areas offering little room to manoeuvre, for example.
  • Safety: immediate safety ensured, low vibration, levels during pile driving, and strong safety record with more than 5,000 km of piles installed over 30 years.
