Information

Procedures to follow when a sinkhole develops on private property.

  • Determine if the sinkhole is impacting any utility services (gas, water, electric, sanitary).  If sinkhole is impacting a utility, contact that utility company directly

  • If sinkhole is located close to the home, check for structural damage (settlement cracking) in basement and at interior wall seams/joints

  •  Ensure that the sinkhole area is blocked off from children, pets, pedestrians to avoid potential for injury

  •  In areas of high to medium density housing, determine if sinkhole is in an area where former cesspool or septic system was located, as a collapsed system can mimic the subsidence feature

  •  Contact a local construction contractor to assess the situation.  Typically, a sinkhole can be remedied by excavation and filling an exposed “throat” with a bentonite (clayey) grout mixture or concrete mixture known as “flowable fill” to provide a manmade plug. 

  •  Consider maintaining subsidence/sinkhole insurance

  •  Call the Engineering Services Office (610-678-5393) to report the occurrence so the location can be recorded onto the Township sinkhole database. 

  •  Literature on sinkholes is available from the Engineering Services Office and is free of charge or can be obtained at the Department of Conservation and Natural Resources website at: www.dcnr.state.pa.us/topogeo/ - click on Geologic Hazards Heading, then Sinkholes where “Sinkholes in Pennsylvania” booklet can be downloaded.

  •  If sinkhole is discovered in the public right-of-way, contact the Township
