Your all in one geotechnical solution provider

Terratech provides one stop geotechnical solutions to our clients. With our extensive expertise, superior equipment and design capabilities, we cover a whole range of services that will ensure your project meets or exceeds all requirements and that all necessary support is fully provided.
Terratech Triple Fluid Jet Grouting
Triple Fluid jet grouting allows for flexibility on the amount of cement grout injected into the system and makes the formation of very high strength jet grout mass. We are the only company who can offer this in Singapore.
TerRATECH IMProved double tube system
Developed by Terratech Engineering – using special long nozzle, high flow rate & Anti Turbulence design for better cutting energy. We can jet grout in very stiff soils and also very soft marine clays at low cost.

specialised and comprehensive

Our services are comprehensive and cover not just our immediate areas of responsibility but we also provide support on issues surrounding the works. We frequently help with impact assessment of our jet grouting works, provide design and advice for excavation systems, and also project management advice. We employ the cutting edge methods and the latest machinery designed to our specifications.

Terratech is the only company to offer triple fluid jet grouting Singapore, which is superior to single and double fluid systems.

Unlike single and double fluid systems where the grout jet is also the disintegration jet, triple fluid systems have a separate disintegration jet with the grout jet below the water jet introduces cement grout to mix and displace the soil / water mix formed by the disintegration jet.
Separate disintegration and grout jets allows flexibility on amount of cement grout injected into the system, allowing for the formation of very high strength jet grout mass which the other methods cannot achieve.
Greater amount of water used leading to slurry being less viscous.
Smaller pressure head of the slurry ejected to ground surface.
Smaller outwards ground movement when jet grouting in marine clay.

Triple Fluid Method at LTA TEL T228 at the
banks of Marina Barrage waterway

Terratech to the rescue

Terratech was engaged for T228 and T302 after proving that it is able to control ground movement. Using parameters similar to T225, Terratech conducted jet grouting works at diaphragm wall contact zone between wall and installed DSM mass (the DSM installation by others had already caused significant wall movement).

Jet grouting was also installed at the banks of the Marina Barrage waterway where the slurry was not allowed to find its way into the water.

All works were done successfully and the diameter and strength were also achieved.

Being proficient with the technology, Terratech was able to recognize the potential of and deploy a new technological double fluid system.

Using this system coupled with the high range pumps, we are able to jet grout in very stiff soils up to SPT N=50 and also jet grout soft marine clays at low cost.

This technique is also useful where very large diameter jet grout columns are needed (e.g. utility gap) up to 4.5m diameter.
