Detectives want to speak with anyone with information about a floor that was dug up and re-laid in the area around Easter 1989. The floor could be internal or external.
The search for the remains of the 19-year-old was suspended on Monday, after police received new information.
In a statement, PSNI Detective Chief Inspector Gary Crawford said: "We are extremely grateful to members of the public who have come forward with information to assist our enquiries.
"This information will require further assessment and planning before the investigation can continue in its search phase."
The investigation, which started after new information was obtained in August, has focused on ground near the Hanover Street flat where Caroline had been living with her boyfriend.
Police had asked anyone who lived in the area or in Carleton Street and Church Street at the time to come forward - and on Friday they turned their attention to a nearby house which is currently being used as a business.
Following the new information, DCI Crawford said the operation has been suspended and detectives plan to liaise with a number of other agencies in the coming days.
He continued: "Police intend to return to the Carleton Street area in the near future to resume search activity.
"Even though people have provided information to us as a result of recent appeals I would continue to urge anyone who knows what happened to Caroline to contact Police."
DCI Crawford said he believed police are close to finding Caroline and any information received on building work could lead them to where her body is located.
"There was building work going on in the area, we know that, but we need to know specifically where it was," he said.
Anyone with more information can phone detectives on 07585 22 82 83 or 0845 600 8000.
