Barrettes
They can be designed as single elements as well as cross, T, L or polygonal circular elements. They transfer the applied loads via peak pressure and skin friction.
The use of barrettes instead of large-diameter bored piles is recommended when, for example, the excavation pit is enclosed with a diaphragm wall and the construction site equipment and devices are therefore available on site.
