Cat & Genny surveys with trained operators
A CAT and Genny is a good method of tracing metallic services. However in the wrong hands they can be difficult to rely on. At mantra we have fully trained surveyors and as part of The Surveyors Toolbox, the CAT and Genny is a cost effective method of services detection.

Drainage surveys and tracing
Using CAT and Genny with a sonde and GPR technology all existing site drainage can be traced with invert and cover levels checked. On redevelopment sites this can be a critical cost saving exercise when drainage elements are to be re-used.

Ground penetrating radar surveys for utilities
Another part of The Surveyors Toolbox. Ground probing radar allows us to "see underground". We can identify non metallic services such as water and gas, buried chambers and tanks. A full utility mapping survey before you begin excavation can save you time and money in the long haul, in addition to reducing your accident statistics.

Geophysical surveys
Also with the use of Ground Probing Radar we are able to identify changes in terrain and strata underground. This can have many uses including identifying surfacing depths and locating archealogical features for a dig.

3d view of underground relationships available
Using our software technology we can produce a 3d picture of what is underground from our radar scans. Whether this is for utility relationships or geophysical purposes, this allows a physical picture to be viewed of what you are unable to see from the surface.
