Case study: York NHS – Scarborough Hospital (final phase)

The company was appointed by York NHS Teaching Hospital to carry out works to Scarborough Hospital. This followed previous work to the boiler house roof and two of the hospital’s plant rooms.

The roof coverings had failed on the Anne Wright ward block. Weathering over the years and water ingress had caused issues.


  • The existing inverted roof was being supported by insulation and paving stones which were holding it in place. This was replaced by a Sika Liquid Plastic Ultra 20 System.
  • As a working hospital, the area needed to be segregated.
  • As the building was over 3 storeys high and there was a lot of material to be removed from the roof, a significant scaffold walkway was required to transport the waste material to skips.
  • Channels were created in the new roof coverings to allow better drainage of rain water to outlets.
  • The new thermal upgrade provides the hospital with a 20 year guarantee.
  • The use of Sika Decothane Ultra provides a seamless system that is installed without the need for hot works.
  • The parapet walls were also in a poor state and needed attention including crack stitching repairs.

Customer Feedback:

The finished roof covering could not be more of a contrast from the original, improved environmental performance, improved drainage, long term guarantee and now a safe accessible for servicing equipment.
