Ground Investigation
GPR support for ground investigation: voids, made-ground, buried features.
Ground investigation GPR from Corvus is part of our large-scale gpr service. Ground investigation projects use GPR to support boreholes and trial pits. We map voids, made-ground variability, and buried features so the GI design and interpretation rest on full coverage rather than point samples.
Built around the question being asked.
A vehicle-towed or pushed array surveys the site in lanes. Multiple frequencies capture both shallow services and deeper features. Data is processed into depth slices and combined with locator and topographic data to produce a single accurate plan.
For ground investigation specifically, the brief drives the choice of frequency, density, and reporting style. We quote a method that fits your access window, your accuracy requirement, and the downstream use of the data.
