What surfaces can Ground Penetrating Radar be used for?
Ground-penetrating radar scans accurately through most cemetery surfaces—lush turf, bare soil, gravel drives, asphalt lanes, concrete walkways, and even brick or paver plazas—without disturbing the grounds. Whether your plots sit under manicured lawn or beneath a paved road, Sentry Mapping's GPR equipment can still detect every marked or unmarked burial.
Ground penetrating radar cemetery surveys work on virtually any surface you’ll encounter in a burial ground. The high-frequency antennas Sentry Mapping uses read clean echoes through manicured grass, compacted soil, sand, clay, or loam. Because the radar signal is transmitted and received from a wheeled cart that rolls along the ground, it also performs well over hardscapes such as asphalt drive lanes, concrete walkways, gravel paths, brick or stone pavers, and even thin decorative slabs. This versatility lets our technicians scan every corner of your cemetery—between headstones, under tree canopies, through columbarium plazas, and across parking areas—without cutting, coring, or excavation.
Moisture, surface texture, and minor topography rarely pose problems; in fact, slightly damp soil can improve signal clarity, allowing unmarked grave detection down to eight or ten feet. By combining this all-terrain GPR capability with centimeter-grade GPS, Sentry Mapping delivers precise burial plot mapping and digital cemetery mapping that integrates seamlessly with our optional cemetery management software. The outcome: a complete, searchable grave locating map staff and visitors can trust, while the grounds stay pristine and undisturbed.
