Ground Penetrating Radar Surveys

chimney flue location 1
Chimney flue location
Ground Penetrating Radar (GPR) is an ideal technique for locating chimney flues in buildings. GPR is an entirely non-destructive and non-invasive technology (NDT), requiring only access to the surfaces of the walls to be surveyed. A GPR chimney flue location survey will cause no damage to the building and there is no requirement to drill or otherwise use intrusive investigation methods...

Rebar detection (Ferroscan)
GPR is completely non-destructive and non-invasive technology (NDT) and can reliably detect rebar to a depth of approximately 50cm (or greater if the spacing between rebars is not close and a lower frequency antenna can be used. However GPR does have some limitations: it is not able to penetrate through a closely spaced mesh or reinforcing metal fibres, or very closely…
rebar detection
Concrete imaging and rebar mapping
Using GPR (Ground Penetrating Radar) we can perform concrete imaging and rebar mapping surveys, providing structural information for the distribution of rebar throughout the surveyed area including the spacing and depth of the different rebar layers, the thickness of the concrete cover and screed, and clear imaging of features within the concrete including conduits, cables and drainage...
concrete-slab-survey-ft
Concrete floor slab surveys
A Ground Penetrating Radar (GPR) survey is the ideal method for surveying concrete floor slabs such as those in warehouses, buildings, factories, depos and car parks. A GPR concrete floor slab survey can determine structural information including the slab thickness, distribution of reinforcing bars and the locations of pile caps and ground beams. Depending on the density of the rebar within…
underground-void-detection-featured
Underground void detection
GPR is a fully non-destructive and non-intrusive technology (NDT), it is ideal to survey larger areas and focus attention for remedial works or trial holes in the right places. GPR works by transmitting an electromagnetic signal into the ground, reflections are caused by changes in the electrical properties of the material the signal is travelling through and those reflections are recorded…
underfloor-heating-pipes-location-ft
Locating under-floor heating pipes
The locations of under-floor heating pipes can be seen in the GPR data and marked directly on the floor surface on site. Alternatively, if a map showing the locations of the under-floor heating pipes is required, it can be more efficient to collect GPR data and save it for office based post-processing and interpretation. In this case the saved data is…
pavement analysis
Pavement surveys
GPR is entirely non-destructive (NDT) technology, which can be deployed from a vehicle operating at traffic speeds without the requirement for road closures or traffic management, or by personal collecting the data by hand (depending on the type of road or area to be surveyed). Other pavement survey methods such as FWD (Falling Weight Deflectometer) and core samples…
utility detection
Utility surveys
Ground Penetrating Radar can detect most types of utility, including metal, plastic, clay and concrete pipes, cables, and utilities for which there might be no manhole access, which could be difficult to trace using Electromagnetic Location (EML) methods without the ability to clamp on and induce a signal. GPR is also able to detect and map the extents of underground rebar…
