Changes in soil prove especially harmfull to tunnels. Conventional construction methods require huge efforts to correct issues like shifts and moisture level changes, since building materials need to be perfectly distributed inside gaps or cracks. Liquid soil does not have these problems. It's temporary liquid state allows it to flow into every corner, crack or gap, where it then solidifies. Therefore, big operations on the tunnel's walls are eliminated completly. Alongside it's great utility and suitability in new tunnel constructions, acting as an optimal solution for base layering, liquid soil offers vibration decoupling. Ultimately, liquid soil's temporary liquid state allows projects to save a tremendous amount of time, because of it's ability to compress by itself, removing the use of compressing machinery entirely.
