Internationally recognised as a leading way to improve weak or permeable soil, jet grouting is an effective solution for a wide range of ground types and scenarios.
The jet grouting process involves disaggregating the soil or weak rock and mixing it with, as well as partially replacing it with, a cementing agent. The disaggregation is achieved by means of high pressure jets of fluid which can be the cementing agent itself.
Jet grouting uses lightweight, small sized drilling rigs and can be successfully performed in confined spaces, restricted sites and situations that require work to be carried out around obstructions. Jet grouting is a mobile system that does not disrupt construction works, saving time and cost.
