Versatility of Compaction Grouting to Stabilize and Lift Large Structures-Video

Video Transcription

Video Summary

Keller engineers used compaction grouting to stabilize and re-level two structures with significant differential settlement. In South Dakota, a 105-foot grain bin had tilted about five inches, preventing further loading. Grouting was sequenced around its ring foundation, bringing it nearly level and allowing operations to resume. In Utah, an office building had settled up to 3.5 inches near its stair core. Crews first stabilized the foundation, then carefully lifted sections in small stages to avoid damage; push piers supported the stair core. The floor was restored to within an eighth of an inch of its original design, with no later movement reported.
