Especially for near-surface (0-15m) investigations typical of Civil and Environmental Engineering projects, Ground penetrating Radar technology offers unrivalled detailed resolution of any subsurface infrastructural services, Sinkholes and subsidence and highlighting geochemical anomalies related to contamination, spillage and leakages in pipes.
Whether the project location is in a highly developed congested metropolitan setting or a new land-opening green area, we have unlimited choice of multi-frequency shielded and unshielded antenna to pull-off clean repeatable data against challenges of EM-coupling and noise.
Depending on the job specifications, we can acquire data in 2D profiles lines or collated 3D grid and process it accordingly to be presented as profile sections or volumetric deliverables enabling multi-dimensional extract of information (vertical slice, depth-slice, side-view rotations)
Underground services detection
Sinkhole and Subsidence detection
Leakages in Concrete bunds
Detecting geochemical anomalies and mapping extent.
In accordance to ASTM D6432 – 99: Standard Guide for Using the Surface Ground Penetrating Radar Method, we utilise a range of antenna (frequency 15MHz to 800MHz) for Subsurface Investigation, data is acquired and processed in either 2D/ 3D formats.
The AS 5488-2013 Standard is used for risk management underground services locating procedure, marking and reporting.
Data Processing and Interpretation
Data processing and interpretation is done using industry-standard software(s) namely (REFLEXW™, RADAN 7 and presented to industry standards.
