BOREHOLE EXCAVATION CLEARANCE SURVEYS LONDON AND SURREY UK.
Cadmap Limited provide Borehole Clearance surveys using underground utility methods to ensure the ground is clear of any buried utilities. Covering London and the South UK.
If you are planning on digging, drilling excavations or boreholes or soil testings it is recommended to obtain a utility clearance survey. This involved mapping any buried services within the area and giving the all clear to proceed with any excavating in the area.
Methods used for Borehole Excavation Clearance Surveys. UK
Ground-Penetrating Radar (GPR):
- Principle: GPR uses high-frequency electromagnetic pulses to penetrate the ground and detect changes in subsurface materials and structures.
- Advantages: Can detect both metallic and non-metallic objects, provides real-time data, and can cover large areas relatively quickly.
- Limitations: Limited penetration depth, effectiveness decreases in highly conductive or clay-rich soils.
Electromagnetic (EM) Survey:
- Principle: EM surveys use electromagnetic induction to detect variations in subsurface conductivity.
- Advantages: Effective for detecting metallic objects, can cover large areas rapidly, and provides depth estimates.
- Limitations: Less effective in areas with high levels of electromagnetic interference, limited penetration depth compared to GPR.
