Jet grouting is an injection system based on extreme high pressure that can be used in all types of soil. Grout bodies of a pre-determined shape, height and depth can be constructed to create a screen or wall. The strength of the grout and the addition of reinforcement allows for the construction of load-bearing and retaining subterranean structures. The system is vibration-free and low-noise and can be used in confined spaces. It goes without saying that quality control and monitoring are very important.
Applications include:
- repair of old foundations
- soil stabilisation
- soil-retaining structures
- sealing of sheet pile connections and leaks
- sealing of pipeline/sheetpile junctions
- sealing of building pits for horizontal drilling
- isolation of contamined soil
Registration and monitoring of:
- drilling process and drilling depth,
- lifting and rotating speed,
- injection flow and pressure of grout, water and air,
- grout suspension,
- excavated grout suspension.
Depending on the design requirements, ambient factors and soil condition, three different installation systems can be used (1, 2 and 3 phases).
Applications include:
- repair of old foundations
- soil stabilisation
- soil-retaining structures
- sealing of sheet pile connections and leaks
- sealing of pipeline/sheetpile junctions
- sealing of building pits for horizontal drilling
- isolation of contamined soil
