Deep Cement Stabilisation (DCS) Method

Improvement Principle	Solid
Relative mixing caused by the reverse rotation of outer & inner blade to mix the curing agent the slurry & the ground uniformly so as to create a uniformly improved substance. It is able to form max 2.5m diameter improved substance to reduce construction period & construction cost .

Advantages	Able to reduce the work duration & construction cost by large diameter.
	Able to produce uniform improved substance through composite relative mixing.
	Able to apply to hard ground because of its heavy duty mixing equipment.
Disadvantages	Construction cost is high as compared to compaction method.
	Unable to perform installation work close to structures due to mechanical stirrer.
	Need to dispose the upheaval soil as construction work in progress.
Applicable Ground	Mostly all types of soil such as sandy soil, cohesive soil, and organic soil etc.
Objectives	Structural Foundation, Prevent Slip Circle, Prevent Settlement, Prevent Liquefaction
Improvement Effectiveness	Cohesive Soil	Increase Strength
		Reduce Settlement
		Suppress Shear Deformation
	Sandy Soil	Reduce Settlement
	Sandy Soil	Prevent Liquefaction
