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.
