Vibro­replacement
Deep compaction

Vibro-replacement is used to improve cohesive soil types. Thereby, coarse extraneous material is filled into the vibrating hopper and a load-bearing gravel or crushed stone column is produced. If the crushed stone columns are arranged in a grid the building ground can be improved area-wide.

Procedure for the production of vibro-replacement columns with top vibrator

1. Positioning the casing at the column point

2. Vibrating the casing down to the final depth, thereby pre-compacting the soil

3. After reaching the final depth, inserting the fill material into the receiver hopper and starting compaction

4. As the column is compacted, staged extraction of the casing, filling the cavity with fill material

5. Re-penetrating the casing to compact the fill material

6. Completed vibro-replacement column

Foundation concept

Filling with extraneous material with subsequent stuffing creates a load-bearing gravel column with a greater strength than the untreated ground.
