How many boreholes are needed for a solar farm?

The number and spacing of boreholes or trial pits depends on site area and variability. A typical approach for solar farms is one investigation point per 0.5–1 ha, adjusted based on initial findings.

Can you carry out resistivity surveys for earthing design?

Yes — earth resistivity surveys using the Wenner method are part of our geotechnical services and provide the input data for Substation and solar farm earthing design.

How quickly can you mobilise for a site investigation?

We can typically mobilise within 1–2 weeks of instruction for standard site investigations, subject to site access and equipment availability.
