About

RIC Australia (Pty) Ltd is a specialist geotechnical contractor which concentrate on rehabilitating problematic soil conditions by means of first world technologies.

RIC is a technique allied to Dynamic Compaction that can be used to increase the bearing capacity of soils through controlled Impact.

The treatment is effective in the top layers typically up to 6m depth, though improvements up to 9m have been seen in some conditions.

A drop weight of 9 to 12 tonnes (depending on size) is dropped onto a special foot assembly 40-60 blows a minute. The foot remains in contact with the ground at all times

Applications

  •  Surface Consolidation: 
  • Foundations Support:
  • Floor Slab Support:
  • Liquefaction Mitigation:
  • Waste Stabilization:
  • Stone Columns
  • Material replacement

The machine is accurately controlled from excavator cab and the degree of compaction electronically monitored.

The impact foot is in contact with the ground at all time and eliminates the risk of flying debris. Unlike conventional DC; other activities can take place in close proximity

The impact energy and soil deflection are recorded by the on -board computer for presentation of compaction data to site managers. Results can verify work done to the client.

The data can highlight weak zones where extra fill is required, or zones where underground obstructions were present (i.e. previously hidden old foundations)

The unit is mounted on standard excavators, typically in the 40-85 tonne class and can be mobilised in minutes from arrival on site.

Final treatment of upper strata following traditional DC of the deeper layers. Increase bearing capacity and reduce settlement.

  • Stiffen soils and create uniform bearing conditions.
  • Increase shear wave modulus to help raise seismic site class.
  •  Reduce waste volume and improve properties of loose fills.
  • RIC has been successfully used to consolidate Gravel, Sands, Silts*, Miscellaneous fills and industrial and mining waste
  • The ability to dump and compact sand or stone to depths up to 6m simplifies remediation practices. RIC is also less expensive than over-excavation and replacement techniques.
