Micropiles

Acro BTP > Improvement > Micropiles

A micropile is a narrow cross-section pile (diameter: 80mm to 250mm) that can be up to 20 metres long. Laid out in a group to form or consolidate a structure, with ACRO BTP’s know-how the micropile provides two types of anchorage related to:

The friction of the micropile in the ground surrounding it, which thereby offers pile driving resistance
The end-bearing effect corresponding to the foundation’s vertical support on ground of an acceptable quality.

In the case of stable ground located too deep, the micropile functions exclusively on friction resistance. The number of required micropiles is determined by calculating load distributions by combining the structure’s actions and by a geotechnical study of the native soil.
