MANHOLE FRAME REPLACEMENT

METHOD

  • Make a rectangular saw cut in the road surface approximately 200mm from the frame edge. Remove the frame and all damaged tarmac, concrete and bedding mortar.
  • Make good the seating and bed the frame with fast setting repair mortar. Allow the bedding mortar to set then fill up to within 50mm of the traffic surface with fast setting repair concrete and allow to harden.
  • Spray prime all vertical surfaces and apply replacement tarmac to excess.
  • Compact the replacement tarmac back to the traffic surface level and reopen to traffic.
