Scope

High-pressure spray grouting is mainly suitable for spraying in quaternary soil layers such as clay soil, sandy soil, loess, silt and artificial fill soil, and has good reinforcement effects. However, for gravel diameter greater than 60mm, excessive gravel content, and humus soil containing a large amount of fiber, the spray quality is poor and it is generally not suitable to be used.
