Vibro Stone Columns To improve the load bearing capacity of in-situ soils and fills, Vibro stone columns are designed and are used. These columns reduce the differential settlements of non-homogeneous and compressible soils which allows the use of shallow footings and thinner base slabs. For the construction of Vibro stone columns, the vibrator is made … Read more
Rapid Impact Compaction Rapid Impact Compaction is a shallow ground improvement and densification technique. This method densifies shallow, granular soils, which repeatedly strike an impact plate on the ground surface using a hydraulic hammer. The energy is transferred to the underlying loose soils and regroups the particles into a denser formation. The impact locations are … Read more
DEEP SOIL MIXING The properties of soft cohesive soils can be improved by mixing of a variety of chemical additives. The addition of lime, fly ash and cement in different combinations can significantly improve the shear strength and compression properties of such soils. Other additives can be used to fix pollutants in place to prevent … Read more
Ground Improvement Ground Improvement or Ground treatment is defined as “controlled alteration of the state, nature or mass behavior of ground materials to achieve an intended satisfactory response to existing or projected environmental and engineering actions” Ground Improvement by Vibration Vibration can be used to compact soils and fills. Similar to Vibrating rollers used to … Read more
