GeoConcrete® Column System
begins by driving a closed system displacement mandrel, supplied with concrete,
down to the dense bearing stratum. The mandrel is stroked up and down
successively to build an expanded concrete base to optimize load transfer into
the bearing layer.
Following base construction, the mandrel is withdrawn while
maintaining a positive internal pressure to expel the remaining concrete into
the columnar soil cavity created by the mandrel. The closed system of the
GeoConcrete Column mandrel allows for robust quality control monitoring during
the construction process which ensures the installation of a high quality
The GeoConcrete® Column System provides high capacity, rigid elements with superior levels of performance for foundation support and settlement control. This technology can provide an excellent alternative to deep foundations, including driven piles, drilled shafts or augered cast-in-place piles.
