Sewer manholes are an extremely important element of the equipment of each road. Improper placement of them on the road surface results in numerous damage to vehicles, and sometimes even leads to road collisions. The replacement, assembly and adjustment of manholes are currently the most common steps taken by infrastructure managers. Thanks to many modern tools, such as: quick-setting mortars, circular saws for cutting manholes, and handles for lifting manholes, the work becomes quick and less burdensome. Our offer includes the replacement of an ordinary sewer manhole with its self-leveling counterpart. To this end, we uncover old manholes and the necessary space in their close vicinity and remove debris from the working space. We also get rid of loose and damaged elements of the foundation or leveling rings and rebuild these elements of the structure. Then install the adaptation ring of the new self-leveling manhole and pour it over with a quick-setting mortar. The penultimate stage is the application of auxiliary formwork, which allows the asphalt road material to be applied and its preliminary compaction. At the very end, we remove the formwork to install a self-leveling sewer hatch. Of course, all surface defects near the manholes are also repaired by us.
