VIBRO COMPACTION

Vibrocompaction, originating in Germany in 1936, is a highly effective method for compacting non-cohesive soils. This technique uses deep vibration probes, suspended from a crane, to densify the soil. Settlement at the ground surface and load tests assess soil compaction and bearing capacity improvements, respectively. Cone Penetration Tests (CPT) verify soil property enhancements before and after compaction. 

During vibrocompaction, strategic points in triangular or square patterns are targeted for comprehensive soil improvement. A cylindrical vibrator, suspended from a crane, oscillates horizontally to depths using extension tubes. These tubes also house water and optional air supply pipes to aid ground penetration. Settlement can range from 5% to 15% of the compaction depth, based on initial soil density and desired compaction level. For more in-depth technical details, refer to specialized literature on vibrocompaction.

VIBROREPLACEMENT AND STONE COLUMNS

Vibrocompaction, pioneered in Germany in 1936, stands as a highly effective method for compacting non-cohesive soils. This technique utilizes deep vibration probes suspended from cranes to densify the soil, measured by settlement at the surface and evaluated through zone load tests and Cone Penetration Tests (CPT) for soil property improvements.

APCC excels in Vibrocompaction and Vibroreplacement, boasting a fleet of over 50 probes and skilled personnel capable of enhancing large areas without outsourcing. They have successfully undertaken ground improvement projects for notable developments like Ba Al Ghaiylam Development, A'Sharq in Oman, and various projects across the Middle East.

Vibroreplacement, an advanced technique building on Vibrocompaction, involves inserting crushed stone or coarse materials into holes created by Vibrocompaction probes. After removal of the vibrator, the void is filled and compacted through repetitive vibrations. This method strengthens weak natural soils and man-made fills, particularly suitable for housing and low-rise buildings, employing the conventional dry method.
