Berg Construction completed sinkhole remediation work, addressing various issues to ensure long-term stability and safety:

  • Removal and replacement of compromised storm sewer pipe due to sinkhole development underneath sections of the pipe run.
  • Implementation of multiple techniques to mitigate future sinkhole occurrences within the stormwater basin.
  • Utilization of compaction grouting to stabilize the subgrade surrounding the pipe run.
  • Application of flowable fill directly into voids to prevent further damage to the area.
  • Installation of inverted filters and concrete collars to stabilize the storm pipe run, facilitating natural groundwater percolation while preventing excess soil movement.
