MR² Method

Repair work for the top section of manholes

Outline

MR2 Method is a repair technique for the top section of manholes.
This technique allows for the low-noise, low-vibration, and quick elimination of level differences between the top of a manhole and the surrounding pavement surface, as well as replacement work due to aging or deterioration of the iron cover or frame. This technique is space-efficient and cost-effective. It can be safely implemented at night and in residential areas. The pavement around a manhole is vulnerable to damage due to insufficient compaction. This technique prevents insufficient compaction, which can occur because of factors like temperature drops, because the pavement around a manhole is constructed with a cold mix. MR2 Hybrid is used as the surface course material.

Features

  1. The Manhole Remover operates with low noise and minimal vibration.
  2. The MR2 Mortar, which hardens extremely quickly without shrinking, can significantly reduce work time.
  3. The road can be reopened to traffic in less than two hours from the start of the work, making this technique ideal for heavy traffic areas.
  4. Using spacers allows construction to be carried out on slopes and uneven road surfaces.
  5. Traffic obstacles, such as level differences from road pavement work, can be eliminated, and road flatness can be improved.

Applications

  • Repairs in areas where noise and vibration need to be minimized, such as during nighttime and in residential areas
  • Repairs in high-traffic areas and areas where road closures are not possible
  • Repairs in areas where roads need to be reopened to traffic quickly
