VHP Grouting / Jet Grouting

Very High Pressure grouting (VHP) or jet grouting consists in mixing the soil on site with a water cement mixture (grout), thus forming grout columns which can serve as foundation elements, general soil consolidation, earth-retaining elements or anchoring.

By using drilling rods with a limited diameter (about 80 mm), grout columns can be placed under existing walls and/or foundations.
