PT. REKAKARYA GEOTEKNIK (REKA) is an Indonesian company with extensive local experience well supported by international expertise. REKA is a specialist EPC ground improvement contractor.


REKA offers technically advanced, innovative and cost effective ground improvement solutions for various ground conditions. Applying REKA engineering excellence and innovation to provide tailor-made solutions to meet the requirements of clients. REKA is committed to providing reliable solutions to the client while:-

       - Delivering results timely;

       - Promoting environment, healthy and safety;

       - Assuring qualiy and reliability.




REKA believes in engaging with clients at the earliest stage of a project where value engineering can be optimized. From the project conseptualization stage, a comprehensive program of site investigation can be formulated leading to the development of Design-and-Build solutions. During design stage, REKA's technical expertise provides innovative designs, reliable schedules and quantities as well as predictable construction outcomes. During construction, REKA is committed to the highest degree of health and safety on site, quality and dependability, environmental preservation and sustainability. REKA maintains unparalleled resources of plant and equipment along with experienced personnel.




REKA offers a wide spectrum of ground improvement tecniques. REKA strives to provide customized solutions for a variety of ground conditions from very soft clays to very loose sands, and for varying degree of improvement such as settlement control, improving bearing capacity and stability and anti-liquefaction treatment.


REKA has 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)


REKA also provides geotechnical analysis & design and execution for foundation works, such as bored pile, minipile, ground anchor, jet grouting, curtain grouting & consolidation grouting.




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.

Depending on the type of ground improvement techniques used and the acceptance criteria set-forth, a typical QA/QC programme may consist of field monitoring as well as real-time data measurement and acquisition as the works progress.
