Soletanche Bachy presents its complete range of piles: continuous flight auger piles.<\/strong><\/p>\n<\/div>

CFA (Continuous Flight Auger) piles are often used for deep foundations or for discontinuous retaining walls.<\/p>\n<\/div>

What is a continuous flight auger pile (CFA) ?<\/h2><\/div>

Piles are defined as structural elements placed in the ground to transfer loads and reduce deformation.<\/strong> Their aspect ratio is unlimited. Pile shafts can be straight, telescopic, wide and with a wide base or prefabricated.<\/p>\n

Piles are either isolated or in groups. They can also form a retaining wall<\/a> i<\/strong>n the form of either a mixed curtain wall, adjoining piles, secant piles or a composite curtain wall, such as a Berlin-type wall or similar.<\/strong> Piles are also used as stanchions to be integrated into the structure of a building with basement levels.<\/p>\n

These columns are put in place before any earthworks and can be used to bear part of the superstructure load when it is built in parallel with construction of the basement levels. They can be angled according to specifications indicated in the construction standards.<\/p>\n<\/div>

CFA piles are an alternative to bored piles particularly suitable for piles of average depth<\/strong> (generally less than 40m).<\/p>\n

This technique allows faster mobilisation of smaller teams and faster completion speed<\/strong> in specific ground conditions.<\/p>\n

CFA piles can be used as load-bearing piles for structural foundations or to create discontinuous retaining structures, such as a wall in secant piles.<\/p>\n
