The project focused on addressing damage caused by a sinkhole beneath an 18″ HDPE pipe:

  • Removal and replacement of the damaged 18″ HDPE pipe, which extended 50 feet from the sump pit to the failure point.
  • Undercutting and removal of unsuitable soils from the work area to ensure a stable foundation.
  • Installation of an inverted filter within the undercut area, followed by backfilling with suitable material to restore integrity.
  • Backfilling around the replaced pipe with compaction to ensure stability and support.
  • Placement of 150 square feet of asphalt over the work area, restoring the surface beneath the TopGolf play area.
