See the ground change, from inside your structure.

Cosmic-ray muons pass through rock and soil. We count them inside tunnels, basements and grottoes.

  • Nothing emitted, nothing dug

    The structure stays in use.

  • Measured from below

    From inside the tunnel or basement.

  • Where to drill first

    Each result ranks the places to verify.

  • Coverage marked

    You see which ground the muons covered.

What we monitor.

We find metre-scale voids, loose ground and water, and place them on the plan.

  • Tunnels and underground structures

    We watch the ground above and beside the tunnel.

  • Slopes and foundations

    We watch for wash-out and water in the ground from a drainage tunnel, a gallery or a basement.

  • Heritage sites and grottoes

    We watch where water moves into the rock around carved caves, without drilling or touching the walls.
