Secant piles

Pile walls are an effective solution for providing support at great depths, using the cased drilling or CFA method.

Depending on the geotechnical context and the use of the structure, the piles can be made either abutting or secant. The sequence provides a relative seal in the event of the presence of a water table during excavation.

The piles are laid in a primary/secondary sequence, using guide walls to ensure that they are laid to tight tolerances and in a variety of shapes.
