Rapid Impact Compaction (RIC)

Rapid Impact Compaction (RIC) instantly compacts shallow soils with a high-energy tamper. This technology is very economical and ideal for compaction of uncertified fills, and liquefiable soils with depths up to 25 ft.

RIC utilizes a hydraulic hammer, repeatedly striking a 5-foot-diameter compaction plate at a rate of approximately 40 to 50 blows per minute. The energy of the hammer blow is dependent on the mass of the ram and the falling height. Upon striking the plate, the energy transfers into the subgrade strata to induce densification. A predefined “set” criteria allows the operator to determine the effective maximization of energy as indicated by the degree of soil depression observed in response to the hammer blows.
