Fields of application
-
Able to construct piles into highly stratified layers of soil comprising very resistant layers.
-
As a single pile or as an element of a piled wall (contiguous and secant piled walls)
-
Housing, infrastructure and industrial projects
Environmental impact
-
In vibration sensitive areas: no vibration is induced as the pile is formed by a hydraulic boring technique as opposed to a percussive element.
-
In a noise-sensitive environment: low noise level generated compared to other methods of piling.
-
The concrete used to form the pile has a high energy input to make the cement, but this can be offset by the use of ground blast furnace slag as a cement replacement (which would otherwise be a waste product).
-
Removal of soil from the job site (SFA piling is a 'replacement' technique and creates pile spoil which will require disposal).
