Definition

An in‑situ ground‑improvement and soil replacement method that uses one‑ or multi‑fluid high‑pressure jets to cut, erode, and mix native soil with a cementitious grout, producing soil‑cement columns or panels (soilcrete) whose geometry and engineering properties depend on jet parameters, grout mix and ground conditions.

Definition

A ground‑improvement technique in which high‑velocity fluid jets (water, air or a water–cement/chemical grout) are used to erode and entrain in‑situ soil, mixing it with grout that then hardens in place to form engineered columns, panels or blocks of soil–cement (soilcrete) with specified geometry and mechanical properties for underpinning, cutoff, leakage control or stiffness improvement.
