Method Cyljet
Discover Cyljet, our exclusive solution dedicated to Jet Grouting works.
Jet Grouting works involve injecting a high-energy kinetic jet of cement grout to from columns of soil-cement mix. To optimize these works, our team of geophysicists has developed a non-destructive method named Cyljet.
🔎Jet Grouting works involve injecting a high-energy kinetic jet of cement grout to form columns of soil-cement mix. To optimize these works, our team of geophysicists has developed a non-destructive method named Cyljet.Â
This patented geophysical solution addresses three challenges:
âž¡ Quickly control the dimension of the columns (within 24 hours)
âž¡ Use only the strictly necessary quantities of materials
âž¡Optimize the costs and schedule of your construction sites
👉How does Cyljet work?
Cyljet allows in-situ control of the column dimensions following their construction. The solution is based on the Electric Cylinder® method, which enables a 3D electrical investigation around the column. A measuring cable is installed at the core of the column and records the potential differences generated by an induced electric current. The processing and modeling of the recorded data in the columns allow establishing the shape of the constructed column.
âž• Cyljet is a unique method that eliminates the need for coring.
It has been used by our geophysics experts in France, particularly for the renovation of the RER C, the Grand Paris metro works. It has been used as well as on numerous international construction sites like soil consolidation projects such as at Lake Nyos in Cameroon, tunnel or metro projects in New York and San Francisco in the United States, Vancouver in Canada, and Melbourne in Australia.
