L & N Parking Lot Sinkhole Repairs

The work located at L&N Building Parking lot in downtown Louisville, Kentucky consists of a sinkhole that has developed from an unknown cause. The parking lot was built on the former L&N railyard and thus is speculated that buried debris could be a potential cause of the sinkhole. AEI has performed a Geotechnical investigation and recommended excavating soil at the sinkhole location down to a 15’ depth and re-install/compact in lifts as recommended by the Geotechnical report. All the soil excavated from the site should remain on site and placed back into the excavation hole due to prior contamination. The existing asphalt should be reconstructed to match existing pavement thickness, grades, and direction of flow.
