This type of deep foundation is currently by far the most widely used in the world.

SEFI-INTRAFOR produces several types of piles.

None of them provides a universal solution, but each type is designed to meet specific requirements.

The following data are required to define
the most suitable pile :

• the nature of the ground (homogeneous,
  heterogeneous, crumbly,
  cohesive, etc.)
• the area of anchoring
• the presence or absence of water
• the environment
• the templates

The bearing capacity of the pile is determined
by mastery of its method of construction

SEFI-INTRAFOR produces four main
types of pile :

• dry auger piles
• piles sunk with drilling mud
• lined piles, vibro or oscillator driven
  casing
• continuous flight auger piles
