Elimination of road surface irregularities and cracks, repair method for manhole covers "MR2 Method".
By using a specially developed machine to cut shallow grooves into the construction diameter, we eliminate the occurrence of shear marks and steps. Steps not only cause traffic disruptions but also contribute to noise.
The removal of the upper part of the manhole is carried out by connecting the "Manhole Remover" (manhole frame removal device) developed for the MR2 method to a hydraulic power source, operating the horizontal and vertical cylinders to "shear" the pavement slab using the manhole iron frame and the lower frame. To eliminate the occurrence of shear marks, a shallow cutting groove is made along the construction diameter. Additionally, the restoration material for the upper part of the manhole is restored using "MR2 Mortar" and "Pavement Restoration Material," which were specifically developed for the MR2 method. 【Applications】 ● Repair work for aging or damaged manhole covers and frames (hereinafter referred to as "upper part of the manhole"). 【Features】 ● Low noise and low vibration: The removal of the upper part of the manhole using the Manhole Remover (dedicated construction machine) is a low-noise and low-vibration operation, making it safe for nighttime and residential area construction. ● Short time, space-saving, and low cost: Significant reduction in working time and minimization of repair area lead to cost savings. ● Quality assurance: High quality is ensured through construction with dedicated equipment and materials. ● Environmental consideration: Minimization of the repair area helps to reduce the amount of construction by-products generated. ● Aesthetic finish: The use of a circular cutter achieves a clean construction result.

Company information
Since its establishment, our company has played a role in national construction, primarily focusing on the "ground improvement field" with our unique grouting method. Subsequently, in response to the changes in social infrastructure development, we have refined our technologies to adapt to the needs of the times and, at times, acquired new ones to expand our business scope. As a result, we have now established three main pillars: "ground improvement business," "slope disaster prevention business," and "pipeline business."
