Rapid Impact Compaction (RIC) is a ground improvement technique that densifies shallow, loose and, granular soils. Soil treated by this method results in increased density, friction angle, and overall stiffness, which results in increased bearing capacity and decreased settlement of planned structures. Rapid Impact Compaction consists of an excavator-mounted or loader-mounted, hydraulic pile-driving hammer repeatedly striking a circular plate that rests on the ground. Energy is then transferred to the ground safely and efficiently, as the RIC's foot remains in contact with the ground, which avoids concern over flying debris being ejected. Rapid Impact Compaction densifies loose-fill soils of up to 6 m deep or more. Additional benefits of rapid compaction include: an increase of the bearing capacity of the soils, minimization of settlement, and the creation of uniform support for foundation footing. Rapid Impact Compaction is an innovative solution when compared to the time and cost of over-excavation and re-compaction.
Advantages
Treated granular soils and fills have increased density, friction angle, and stiffness
Low cost treatment to soils 3-4m in depth
Enables shallow foundations to be used opposed to deeper more expensive foundation solutions
The machine can be accurately controlled rom the wheel loader or excavator cab and the degree of compaction is electronically monitored.
