Geopier GeoConcrete® Columns

The Geopier GeoConcrete® Column System utilizes a high stiffness, rigid element to transfer loads through weak soils, such as soft clays and organics, down to a suitable bearing layer.

The construction begins by driving a closed ended 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Following base construction, the mandrel is withdrawn while maintaining a positive internal pressure to expel the remaining concrete into the columnar soil cavity created by the mandrel.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 ground-improvement product.

Some attributes of the Geopier GeoConcrete® Column System are:

• Economical – 20% to 50% savings
• No excavation
• No structural slabs or grade beams
• No spoils to dispose
• Suitable for sand, silts, soft clays, organics and fill soils
