The problems at the Ribble Valley hospital stem from issues with the floor screed causing the vinyl floor to debond and lift.
John Wilson, managing director of Eric Wright Construction, said: “Three months after completing the facility, we became aware of some issues relating to the floor finishes.
“Working closely with our client and professional team, we have discovered a technical issue relating to the screed, which we are now working very hard to rectify.
“This has unfortunately meant the temporary closure of a small number of rooms within the facility however we are phasing the replacement to ensure no impact on patient care.”
Martin Morgan, director of estates and facilities at ELHT, told the Lancashire Telegraph: “This is clearly unacceptable and poses a trip hazard to patients, staff and visitors.
“The construction company and the trust have requested an independent investigation by a specialist contractor, who has now inspected the flooring across the whole of the hospital.
“A programme of remedial work is due to begin.”
