Injecting into the ground
Grouting consists of injecting a liquid, suspension, emulsion, or mortar into the ground in order to strengthen it or to reduce its permeability.
Depending on the soil or rock properties, various solutions and methods can be implemented such as permeation, compaction, and jet grouting.
When the grout effectively fills voids in the ground without causing any movement in the surrounding material, it is referred to as fissure or permeation grouting. However, if the surrounding material undergoes displacement due to compression or hydrofracturing, the grouting process is known as compaction grouting or hydrofracture grouting. These distinct grouting methods are employed to address specific conditions and ensure effective void filling while managing the behavior of the surrounding material.
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.
