What Makes Us The Right Choice?

Risk Analysis

When it comes to inspections of manholes, safety and health is important. Because of our priority for health and safety, our reputation for hassle - free manhole inspections in Knowstone has grown. When old covers and frames corrode, they fuse and create unstable hinges which can trap workers' fingers or cause back injuries. By using the right barrier system to keep it stable and the right tools to raise the cover, we can avert such injuries.

We then cut off all external influences by isolating the area. 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. We therefore ensure that all our workers maintain great health prior to and in the course of the manhole inspection process.
