Blasting Technique for Ground Improvement

Blasting Technique for Ground Improvement Blasting is the use of buried explosives to cause the densification of loose cohesion less ground. The principal is that the blasting of explosives in a predetermined pattern causes liquefaction, followed by the expulsion of pore water and subsequent densification of the ground. Blast densification is being utilized for more… Read More »

Vibro Stone Columns | Ground Improvement

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 »
