With our GPR (Ground Penetrating Radar) units and our EM (electromagnetic) wands we can locate and confirm the location of utilities such as water, sewer, sanitary, gas, telephone and data.
We can also locate irrigation pipes, underground storage tanks (USTs) and septic systems down to 20 ft in optimal soil and site conditions, though most locates are contained to the 3ft-8ft depth range.
Back at the office, our EKKO post processing and interpretation software allows us to sharpen the GPR images, and our Voxel software can render 3D images of the subsurface.
Other GPR applications include geotechnical engineering, involving the identification of sinkholes and karst topography, defining near surface stratigraphy and washouts. GPR’s sensitivity to soil water content and geologic structure make it a natural method for hydrogeology investigations, including bathymetry and bottom profiling.
GPR maps offer useful primary survey data that can be used to establish sites for excavation or even identify sensitive areas such as burial sites and the information can guide archaeologists to avoid disturbing or destroying these locations.
What we offer
We use a systematic field approach with GPR technology, and we are aware of its limitations and pitfalls – and its clear benefits. We will not oversell the technology and we will ensure through our proven field experience to provide reliable locates and subsurface interpretation.
The locate process starts with by gathering relevant data of the site. We will ask you for any BC One Call documents, the condition of the site, access constraints, and the availability of any detailed drawings and plans so we can better gauge the scope of the locate and field visit. Essentially, we want to walk through these before the site visit to ensure we understand your needs and how we can best achieve these.
