The compact bentonite units are applied to reduce the external friction
during the piloting process within heavy soil classes which cannot be
readily displaced. They are easy to handle and well suited with the
PERFORATOR machines. The BMAs provide the right mixing ratio and ensure
that the bentonite can be used without delay. The choice of the unit
depends on the specific application conditions as density and viscosity
of the mix have to be adapted to the soil consistency.
