Used in all loose soft rock soils to reinforce them, to reduce permeability

High-pressure jet of fluid breaks, loosens soil, mixes with grout to form columns or other structure

Application includes underpinning buildings, dam cut-off walls, retaining walls, pipe roofing for tunnels or reinforcement of sidewalls, reinforcing quay walls, etc.

Our processes

1. Small diameter drilling is carried out to the desired depth.

2. The drill string is rotated and raised at a controlled speed.

3. A high-pressure jet of grout is sent to the base. The jet of grout erodes and combines with the soil.

4. After the cement has set, the mixture forms a column of soil and concrete.
