Non-Intrusive Mapping Using Multi Sensor Geophysical Arrays
Using ground-penetrating radar, magnetometry, resistivity and microgravity these surveys can identify and position features and hazards beneath the ground, so are an essential pre-construction safeguard on green and brownfield sites.
Benefits of a geophysical survey
- Archaeological preservation. Non-intrusive mapping of historic structures and earth works enable the effective and safe planning of construction projects, removing the risk of damage to artefacts or disturbance to sites of historic importance
- Peace of mind. A geophysical survey is an agreed step in due diligence in construction, to identify if there are areas of archaeological interest, buried hazards or obstructions such as disused mine shafts or unexploded ordnance
- Time and cost savings. Breaking ground presents the highest-risk phase of a construction project. Mitigating risk by establishing as much knowledge as possible offers both cost savings and peace of mind
Geophysical survey applications
- Archaeological prospecting
- Construction sites subject to development
- Historic buildings – eg church and castle grounds
- Void surveys – eg tunnels, drains, buried chambers and tanks
- Historic mine workings
- Locating unexploded ordnance (UXO)
- Rebar mapping
Our expert service
Geophysical surveys are planned to meet client needs as efficiently as possible and add value wherever we can by fully understanding the client’s project needs and gathering data we believe to be pertinent to the project lifecycle.
Interpretation of survey data is presented in clear, digestible reports and drawings, in recognisable formats, to enable decision making with confidence.
We apply the right mix of techniques and equipment to the survey environment/results required.
