What Makes Us Different From Others

Risk Survey

When it comes to inspections of manholes, safety and health is important. We understand this perfectly and have thus built a reputation for hitch free manhole inspections in Trevia. Trapped fingers and back injuries occur due to old frames and covers fusing and rusting together which cause unstable hinges. By working with appropriate tools to lift the cover and holding the barrier in place, we prevent these injuries.

We isolate the area of inspection to prevent outside interruption. This is because we understand that working in confined spaces can be quite challenging and a great deal of physical and psychological hazards go with it. That's why our employees train, both in terms of their skill set and physical ability as well as during manhole inspection processes.
