We have vast experience in solving many different ground problems using one or combinations of the following techniques:

  • Consolidation Methods : Vertical drains | Vacuum Preloading
  • Compaction Methods: Dynamic Compaction | Vibro Compaction | Rapid Impact Compaction
  • Granular Columnar Reinforcement Methods: Dynamic Replacement | Vibro Replacement (Stone Columns)
  • Cementitous Columnar Reinforcement Methods: Displacement Grout Columns | Deep Soil Mixing | Control Modulus Column (CMC) | Kolom Grout Modular




REKA solutions are used across the construction sector in the infrastructure, industrial, commercial and residential verticals.

  • The objectives of incorporating ground improvement techniques are:
  • To improve bearing capacity during construction
  • To improve stability during construction
  • To reduce long-term settlement after construction
  • To mitigate liquefaction during seismic condition



REKA implements a detailed and clear programme of QA/QC during and after ground improvement works. In-situ field tests (e.g. cone penetration tests, pressuremeter tests, etc.) may also be carried out to determine the compliance of field results against the design requirements. Full load tests and settlement monitoring sometime constitute parts of the QA/QC programme.
