More work is taking place this week on the eight-metre-deep sinkhole that appeared in Sheringham High Street two months ago.
The town's deputy mayor Liz Withington said: "An 80m liner was inserted and completed after two extremely long and hot days on Friday, July 26.
"Teams worked until 10pm in difficult conditions to ensure its successful completion. The heat made logistics difficult with the need to keep the liner cool in 30C and prevent the resin from going off before it was inserted."
The large crane has now returned to insert the 1m diameter section of sewer pipe ready for connection to a new manhole.
Repair work is expected to continue into carnival week, which starts on August 3, and the final stage of the process will see the water mains reinstated, allowing the hole to be filled in and highways to begin resurfacing work on the road and pavements.
