Soil mixing is a technique that uses hollows augers to mix cement with soil to form a mixture with improved character in terms of strength and permeability. It is often used as an alternative to trench or pit shoring using conventional methods like beam and wooden lagging, soldier piles, sheet pile, or jet grouting walls. It is also used to consolidate contaminated materials.

Deep soil mixing is vibration free, very low noise method of shoring ideal for use in granular soils where other construction methods are not applicable due to the vibration and noise emissions involved.

It is also a very economical process when compared to other forms of shoring given the right soil conditions. Cost factors in favor of soil mixing are high production rates, absence of aggregate such as sand or gravel in the grout mix, and the fact that no spoils are generated from removal.

The soil mixing process is often combined with conventional shoring techniques as in the installation of secant-pile-walls where the primary piles are mixed and the secondary piles are cast-in-situ concrete bored piles or vice versa.

Too little land, too many people its a common phrase Hongkongers use to describe their city of 7 million people. With a mountainous terrain and a rapidly increasing population, the struggle to find suitable land to build homes, offices and infrastructure has been a constant problem since the former British colony was transformed from a sleepy fishing village into a bustling metropolis.

Hong Kong is just one of many examples where land reclamation contributed to growth and development. Large patches of land in Macau and Singapore, for example, are also created through land reclamation.

Dredging the seabed to remove soft soil and draining water from the seafloor are two common ways to consolidate the foundation. But in locations where the seabed contains significant amount of contaminants, both methods can cause toxic substances to be released and damage marine ecology. Not only will this affect the water quality and marine life, but the contaminants could also enter the food chain and impact on public health.

How to improve the strength of the seabed without disturbing marine ecology in the land reclamation process? Thats the question which led engineers in Japan to develop an innovative ground consolidation method Deep Cement Mixing or DCM.

The process begins by using an auger to drill narrow holes into the seabed. Once the machine reaches the desired depth, a binder material, most commonly cement, is injected to fill the space and mix with the soft mud. Once the cement is hardened, it forms a column embedded in the seabed. This process is repeated multiple times across the area selected for reclamation, creating large groups of columns that significantly increases the load bearing capacity of the seabed.

One of the companys most notable DCM projects is the expansion of Hong Kong International Airport into a Three Runway System. Located north of the airport, consolidation of the soil at the 650 hectares site began in August 2016. Since 40% of the area consists of contaminated mud pits that were generated from dredging in other areas of the city, DCM was favored to limit the potential damage to the environment.

To further prevent toxic substances from being released, Samsung C&T engineers placed a two-meter-thick sand blanket on top of large sheets of geotextile on the seabed before drilling. Working like a filter, the projective layer removes any mud that sticks on the drills when they are lifted.

More recently, Samsung C&T began works on the extension of Tung Chung New Town in Hong Kong in January this year. To help tackle housing shortage in the city, the company will adopt DCM to create 134 hectares of reclaimed land in the northern part of Lantau Island. Expected to be completed by July 2024, the new land will be used to house over 200,000 residents.

The demand for new land will grow as urban centers around the world become more populated. DCM will provide the foundation for meeting the needs of city-dwellers, while ensuring that urbanization can be sustainable.
