  • Title: Ground Radar | Subsurface Imaging
    Descriptive info: What is Ground Radar?.. Ground penetrating radar (GPR) is a high-resolution, shallow penetrating geophysical technique which provides cross-sectional images of reflectors associated with sharp changes in electromagnetic impedance.. A pertinent example is the generation of reflection from the rock/air interfaces defining voids, and reflections signifying underground utilities.. Penetration depth can vary from ~1m up to 30m or more, and depends variably on the geology and the antenna used.. GPR has a well known track record as an efficient and reliable method  ...   Destructive Tests (NDT s) in construction and roading, utility location, and void detection among many other applications.. It is versatile and cost effective, and Subsurface Imaging has an impressive track record of successful suveys employing this technique.. We are also agents for some of the best GPR equipment produced internationally, and can provide components or full systems as per requirements.. Talk to us about what you want to see.. Borehole GPR..

  • Title: Radio Imaging | Subsurface Imaging
    Descriptive info: What is Radio Imaging?.. Electromagnetic Tomography, also known as Radio Imaging Method (RIM) is a method by which an image of the conductivity distribution of the ground between a transmitting antenna and receiving antenna may be obtained.. The method is similar to a medical CT Scan,however our access around the feature of interest is often limited to boreholes or roadways either side of the target.. Thus we acquire a 2D image that represents a slice through the target.. We are also agents for some of the best GPR equipment produced internationally, and can provide components or full systems as per.. requirements.. Equipment.. The RIM equipment is divided into the borehole RIM2 system and the handheld RIM2020 system.. This photo shows the RIM2 transmitter probe:.. Both systems contain H field antennas operating at frequencies of 2.. 5 to 992kHz.. The RIM2 system measures both amplitude and phase data by means of a control unit synchronized transmitter and receiver, whilst the RIM2020 system measures only amplitude information.. The RIM2 probes are 4m long and 45mm wide, enabling a wide selection of holes diameters to be surveyed.. They are connected to winches via 550m of milspec kevlar reinforced fibre optic cable.. The use of fibre  ...   signal is absorbed (attenuated) as it propagates through the earth.. The signal attenuation is a function of the transmission frequency and the electrical conductivity of the media.. By setting up a transmitter at one point and a receiver at another it is possible to measure the signal loss and/or phase change along the path between the two points.. By collecting many overlapping raypaths it is possible to invert the attenuation distribution into an image by use of specialised processing software.. The diagrams below show how the RIM signal is attenuated.. The picture on the right shows typical raypath coverage between 2 boreholes.. A radio signal at a specific frequency travels further through low conductivity media (limestone, coal, potash, meta-sediments, granite) than through materials with high conductivity (shale, mudstone, clay, ore zones etc).. Therefore a conductive ore within a resistive host acts as an excellent RIM target.. The data are processed using the state of the art Imagewin packed from CMTE in Australia.. This package is specifically designed for electromagnetic tomography data and contains algorithms such as weight clamping and central weighting to enhance the tomography dataset..

  • Title: Resistivity Imaging | Subsurface Imaging
    Descriptive info: Multi-electrode resistivity surveys allow for the collection of depth and volume information of subsurface structures through electrical measurements at the surface.. This represents a versatile non-invasive method to accurately assess a wide variety of subsurface features.. Electrodes are arranged in various arrays at the surface, and current is passed through the source-detector system; it is the variations in this transmitted current that is recorded.. By varying the electrode separation and location we can obtain information on subsurface changes in soil resistivity and map these variations with position and depth.. Applications of ERI include  ...   extent of saline intrusion at coastal sites, and in void assessment, especially in clay-rich conductive areas where GPR is ineffective.. Using modern equipment and good survey design this method can be rapidly applied over a large area investigating both shallow and deep soil conditions.. Benefits:.. • Large sites can be investigated.. • Deep soil conditions determined.. • Non-destructive and non-invasive.. • Portable and environmentally neutral.. • Enhance the results from previous electromagnetic induction (EMI) surveys.. Crosshole Imaging.. Geological Imaging.. Imaging Coal.. Imaging Groundwater.. For general info on Resistivity Imaging contact Sebastian Clar:.. biz..
