Tri-Tech were commissioned to undergo an underground survey, which examined the condition of an old culvert in Carlisle.
This survey aids the remote inspection of the culvert to discover its condition and potential failures.
Tri-Techs Elios 2 Drone is perfect for flying into confined spaces such as this. It provides flawless and cutting edge drone data capture in difficult and inaccessible spaces.
