Miksis Services uses Mr. Manhole, an engineered system designed to restore manholes to the correct surface plane. As an additional benefit, defects and infiltration due to faulty risers, chimney and frame are eliminated.
After the defective manhole has been cut away, a new chimney is sealed to the cone. The chimney is cut to allow the frame to sit flush with the surface and a quick drying concrete solution creates a tight collar seal. The procedure is quick and the result is a permanent structure that is leak free, vacuum testable and perfectly level with the road. During the installation process a new insert liner is installed which stops water infiltration and protects the collar from the effects of gasses that accumulate inside the manhole.
