VIBRO COMPACTION

Vibrocompaction, established in 1936 in Germany, is one of the earliest and most effective dynamic deep compaction methods. This technique significantly enhances the compaction of non-cohesive soils, yielding superior results. The process involves densifying soil using deep vibration probes, either single or double, which are suspended from a crane. Soil densification is quantified by the settlement observed at the ground surface, while increases in bearing capacity are evaluated through zone load tests. Further assessment of soil property improvements is conducted using Cone Penetration Tests (CPT) before and after compaction. 

​

During vibrocompaction, points are strategically chosen in either triangular or square patterns to comprehensively improve the targeted area. The process utilizes a cylindrical vibrator that oscillates horizontally, typically suspended from a crane. These vibrators, ranging from 15–40 kN in weight, 30–50 cm in diameter, and 2–5 m in length, reach the desired depth through extension tubes. These tubes also house supply pipes for water and, optionally, air to assist the ground penetration process. The resulting settlement from this compaction can vary from 5% to 15% of the compaction depth, depending on the initial soil density and the desired level of compaction. Detailed technical descriptions and further information on vibrocompaction can be found in specialized literature.

DYNAMIC REPLACEMENT & DYNAMIC COMPACTION

At APCC, we specialize in ground improvement services, including Dynamic Replacement and Dynamic Compaction, to ensure strong and stable foundations for construction projects.

​

Dynamic Compaction involves using heavy weights dropped from a significant height to compact and densify the soil. This method is effective for increasing the load-bearing capacity and reducing the settlement of loose soils.

​

Dynamic Replacement is a similar technique but focuses on replacing weak soils with stronger materials during the compaction process, providing additional stability and support.

​

These ground improvement methods are ideal for projects that require enhanced soil strength and stability, such as industrial sites, buildings, roads, and more. APCC’s expertise and advanced equipment ensure high-quality results that meet project specifications and safety standards.

VIBROREPLACEMENT/STONE COLUMNS

APCC excels in Vibrocompaction and Vibroreplacement, boasting over 50 probes and skilled personnel capable of improving vast areas without outsourcing. Notably, APCC handled ground improvements for significant projects like Ba Al Ghaiylam Development, A'Sharq - Oman, Palm Deira, Palm Jebel Ali and several other project across Middle East.

​

Vibroreplacement is an advanced method building upon Vibrocompaction, involving the insertion of crushed stone or coarse graded materials into holes created by Vibrocompaction probes. Once the vibrator is removed, the resulting cavity is filled with coarse material and compacted using repetitive vibrations. This technique, known as the conventional dry method, strengthens weak natural soils and man-made fills, particularly beneficial for housing and low-rise buildings.
