Infrastructure Foundation Piling in Indonesia

Faced with complex mixed strata of soft soil, sand and gravel, the reverse‑circulation system quickly clears rock cuttings from the hole bottom. It effectively reduces hole‑collapse and mud‑loss hazards, guarantees high‑quality borehole forming and shortens overall construction cycles.

FAQ about RC Drilling Rig

Get a Quote

Q What types of projects are suitable for RC (Reverse Circulation) drilling rigs?

Mainly for mineral exploration, geotechnical survey, large-diameter pile foundation, water-well drilling. Air-powered cuttings removal consumes little water, ideal for arid zones and fractured rock‑layers.

Q What are the differences between RC drilling rigs and direct-circulation or core drilling rigs?

RC rigs use double-wall drill rods. Compressed air flows down the annulus, and rock-chips return through the inner tube. Zero sample contamination, fast penetration speed and high drilling efficiency in hard rock.

Q How do I select the right model? What project parameters need to be provided?

Please provide the following details regarding your project conditions so we can recommend the precise model for your needs: 1.Target maximum drilling depth; 2. Borehole diameter; 3. Formation type (clay, sand/gravel, cobbles, granite); 4. Altitude, ambient temperature, and water availability; 5. Application (gold exploration, pile foundations, water wells).

Q Does the equipment support customization and modification? How are overseas after-sales services handled?

Full-support for OEM & ODM customization. Optional accessories include drill rods, RC DTH hammer, sample collection box and so on. 24/7 online technical support and warranty services are available.
