Ground Improvement

Ground improvement is defined as the alteration of site foundation soils or project earth structures to provide better performance under design and/or operational loading conditions. The ground improvement techniques help to increase the Bearing Capacity of the soils, reduce settlements mitigate liquefaction potential. Ammico as an expert geotechnical contractor has executed several ground improvement projects in GCC region. These solutions include the following:
  • Vibro Compaction (VC)
  • Vibro Replacement -Stone columns (VR)
  • Dynamic Compaction (DC)
  • Dynamic Replacement (DR)
  • Rapid Impact Compaction (RIC)
  • Rigid Inclusions/Controlled Modulus Columns (RI/CMC)
  • Deep Soil Mixing (DSM)
  • Jet grouting

Vibro Compaction is a ground improvement technique used in granular and cohesionless soils such as loose sands, gravels

Stone columns or Vibro Replacement is a technique of Ground Improvement which primarily enhances the performance of weak


Rigid inclusions is a ground improvement method using high deformation modulus columns constructed through compressible soils to reduce settlement and increase bearing capacity.

Rapid Impact Compaction/Rapid Dynamic Compaction (RIC/RDC) is a technique like Dynamic Compaction and can be used to increase

Dynamic Compaction

Dynamic compaction involves the controlled impact of a crane hoisted weight, of 15-20 tons, falling in a pre-determined grid pattern to improve loose, granular, and mixed soils and fills.

Dynamic Replacement (DR) technique is used for compressible soils where fine contents are high e.g., soft clays, silt, sabkha, soils with organic content etc.


Jet grouting uses fluid jetting with a very high kinetic energy to erode the soil structure and mixes the soil particles in-situ with grout.
