ERT from the bottom up

• Price: Price on application

For projects involving soil moisture profile imaging over long periods requiring reliable set-and-forget telemetered operation it is better to image from the bottom up using cable installed in a deep backfilled trench. Software is then used to model layers up to the surface from ERT data collected from clusters of electrodes.

This technique has advantages in:

1. Cracking clay soil,
2. Where farm machinery including ploughs must drive over the site, &
3. Where near surface soil can get extremely dry at times.

The telemetry and electronics can be situated up to 400m from the electrode cable without the need for a booster box.
