Geophysical Explorations


Ground Penetrating Radar (GPR) is a non-intrusive, geophysical reflection technique that provides high resolution imaging of shallow soil layers and ground structures. GPR is utilized by Professional Geologists in Phase I & II environmental site assessments to map the following: USTs, depth to bedrock, depth to the water table and many others. GPR is also the most effective means to map the beginning stages of voids and sinkholes prior to causing severe damage when opened.Locate Buried Drums & Tanks

  • Depth to Water Table/Bedrock
  • Delineate Landfill Limits
  • Locate Leach Lines & Septic Tanks
  • Identify Buried Trenches/Foundations
  • Identify Voids & Sinkholes¬†
  • Delineate Saturation Zones


Cemeteries that have been established for over a century have been recording interment locations with paper and pen for years. If those records get lost or destroyed and the history has been lost forever. The most accurate method available to locate existing burial locations is utilizing Ground Penetrating Radar (GPR).

GPR may be utilized by cemetery professionals as a means to locate unknown/known interments within the sub-surface to preserve the existing locations for future digging. Combining GPR with GPS mapping provides the most accurate means available to record existing interment locations.

GPR is a non-destructive and the technology is completely safe. GPR surveys are completed more quickly & accurately than any other type of investigation. NGPRS, Inc. can map any size cemetery to a depth of 9 to 12 feet locating existing burials and even utility lines and producing a comprehensive site plan of the cemetery.
