Soil stabilization and void filling are required when the foundation is no longer securely fixed to the ground around and beneath it. This occurs primarily from loose soil and dirt around the foundation or a void (created by water erosion or uneven settling) seperating the slab from the compacted earth.
Both situations benefit from pressure grouting to increase the soil's load bearing capacity, increase resistance of lateral movement, and decreasing water flow to structural elements. The pressure grouting procedure can be performed at different stages of construction from pre-excavation to post construction in order to stop settlement of existing structures or those not yet built.
