Manhole

Renovation of manhole structures

The renovation of manhole structures in the sewerage system is just as important as the maintenance of the sewers themselves.

  • Sealing of leaking manholes against ground water using an injection method
  • Manhole surface preparation with water or sand blasting
  • Manhole base repair
  • Corrosion resistant coating using special mortar
  • Renewal of berms and channels
  • Installation and renewal of iron steps to safely access the manhole
