Why Ground Penetrating Radar
Prevent Costly Strikes
Every utility strike averages $56K in damages plus downtime. GPR pinpoints buried utilities, USTs, and voids before your crew breaks ground — protecting budgets, schedules, and safety.
Faster than Test Pits
A typical site is scanned in a single day with non-invasive equipment. No excavation permits, no traffic control, no site restoration — GPR delivers answers before drilling or coring begins.
Regulator-Ready Reports
Georeferenced CAD/GIS utility maps and radargram interpretations formatted for NYC DOB, NJDEP, NJDOT, and LSRP submissions. Fully integrated with Envicon Phase I / Phase II deliverables.

GPR Services & Pricing
From concrete scanning to full-site utility & tank investigations, subsurface intelligence for environmental, civil, and structural projects.
GPR Utility Locating
Pre-excavation planning, Phase II ESA boring layouts, UST location, utility conflict resolution, and NYC DOB / NJDOT permit submittals.
Non-destructive subsurface utility locating using ground penetrating radar to identify buried water, sewer, electric, gas, fiber, and unknown utilities before excavation. SUE-compliant deliverables reduce strike risk on NYC and NJ construction, remediation, and utility projects.
What's Included
- Multi-frequency GPR grid scan (200–900 MHz)
- Electromagnetic (EM) locator sweep for metallic utilities
- Marked locations on-site with paint & flags
- Georeferenced CAD/GIS-ready utility map
- Depth estimates with confidence rating
- ASCE 38 / SUE Quality Level B documentation
Underground Storage Tank (UST) & Void Detection
Phase I ESA follow-up, UST closure planning, LSRP-directed site investigation, and pre-purchase environmental due diligence.
GPR scanning to locate suspected underground storage tanks, abandoned drywells, cesspools, buried debris, and subsurface voids for real estate due diligence, brownfield redevelopment, and NJDEP-mandated Phase I ESA follow-up.
What's Included
- Site walk & historical review of AOCs
- Low-frequency GPR sweep (100–400 MHz) for depth
- Anomaly interpretation by geophysicist
- Field marking of tank/void perimeters
- Written report with radargrams & interpretations
- Coordination with LSRP or Phase II team
Concrete Scanning & Structural GPR
Pre-coring surveys, tenant fit-outs, elevator pit installations, façade anchor layouts, and DOB-filed alterations requiring subsurface verification.
High-frequency GPR (1.6–2.6 GHz) scanning of concrete slabs, walls, and decks to locate rebar, post-tension cables, conduits, and voids before coring, cutting, or anchoring. Prevents costly hits during renovation, MEP retrofits, and structural assessments in NYC and NJ.
What's Included
- 1.6–2.6 GHz antenna scanning grid
- Real-time marking of rebar, PT cables, conduits
- Slab thickness & void identification
- Photo-documented scan locations
- PDF report suitable for structural engineer review
- Coordination with GC and structural team
Certified Geophysicists, One-Stop Deliverable
All GPR surveys are performed by trained geophysicists and interpreted by licensed engineers. When your project also needs a Phase I ESA, LSRP, or UST closure, we bundle the GPR data directly into that scope — no coordinating multiple vendors.

Ground Penetrating Radar FAQ
What is ground penetrating radar (GPR) used for?
GPR is a non-destructive geophysical method that sends radar pulses into the ground or concrete and images subsurface features. It's used to locate buried utilities, underground storage tanks, voids, rebar and post-tension cables in concrete, and archaeological or environmental targets — without excavation.
How much do GPR services cost in NYC and NJ?
Typical Envicon GPR projects range from $1,500 for a small concrete-scanning job to $5,500 for a full-site utility and UST investigation. Pricing depends on site size, required depth, and deliverables (field marking vs. CAD/GIS map vs. ASCE 38 SUE Quality Level B).
How deep can GPR see?
Depth depends on antenna frequency and soil conditions. High-frequency antennas (1.6–2.6 GHz) image the top ~18 inches of concrete in detail; mid-frequency (400–900 MHz) reaches 3–8 ft for utilities; low-frequency (100–200 MHz) can reach 15–30 ft in favorable soils for tank and void detection.
Do I need GPR before a Phase II ESA?
Yes — GPR before boring or excavation is the standard of care. It locates buried utilities and any suspected USTs identified in the Phase I ESA, so the Phase II drill program targets the right Areas of Concern and avoids strikes. Envicon coordinates GPR directly with our LSRPs and Phase II crews.
