YBM concentrates on innovative foundation technology to create a beautiful environment on the Mother- Earth.

Jet Grouting is a most popular method of Foundation Improvement in Japan and overseas.Cement slurry is injected into the ground to increase ground strength and to reduce ground permeability.To make precise concrete column, YBM Jet Grouting Machine has been provided with hydraulic control valves for adjusting slow RPM, automated stepping mechanism, and hydraulic rod chuck and pipe clamp.

◆JET GROUTING

● Foundation pile. (for ground strength )● Underpinning of existing structure.● Downward extension of foundation.● Impermeable seepage cut off.● Earth retention and excavation support.

Jet Grouting with a group of SS40V-600 II For a ground improvement project at Kallang river Singapore, YBM supplied modified type of SI-40S with longer mast. These rigs were installed on sliding rails, and performed continuous & speedy jet grouting to the river bottom.

Cement grout is injected into the soil with high pressure at the monitor nozzle. The jet cut the soi l and mix it with grouts. SINGLE TUBE method is suitable for shallow depth and horizontal jet grout applications.

By using double tube, compressed air is introduced into the jet grout at the monitor nozzle. This increases energy and enable to cut much larger depth. DOUBLE TUBE method creates larger column diameter and is suitable for more deep improvement and cohesive soils.

Soil is cut by compressed air shrouded high-pressure water jet (center), and the space is filled with grout (outer) fromthe lower nozzle. TRIPLE TUBE method is suitable for underpinning, especially cohesive soils and complicate formations.
