Flat Roofing Solutions for Hospitals & Healthcare Buildings

Sika Liquid Plastics has over 50 years’ experience in liquid waterproofing, and have worked across an array of different markets, and healthcare is no exception.


Decothane, our flagship liquid waterproofing products, has been specified amongst some of the largest hospitals in the UK. This is primarily due to the benefits of our liquid waterproofing systems, which are cold applied meaning zero hot works will take place on the roof, as well as the fact that our systems also come with, applications and technical support, and a market leading guarantee.


In addition, we have recently launched Decothane Ultra, a low odour liquid roofing system which has been designed specifically for sensitive sites such as hospitals and healthcare facilities.


During the development of Decothane Ultra, the product itself was tested by Odournet, a team of independent consultants that develops, manages and delivers top level expertise on sensory analysis techniques and their application for product optimisation and material testing.


Deocthane Ultra uses a patented technology which is exclusive to Sika Liquid Plastics, and the system has already been used on extremely complex projects, where compromise wasn’t an option, such as the National Sperm Bank at Birmingham women’s hospital, Scarborough Hospital and the ear, nose and throat facility at Preston Royal Hospital.

The points on the map above highlight a few project case studies and are not indicative of all works in this sector.

Case Studies

Nuffield Hospital, Warwickshire

As part of an on-going programme of works at Nuffield hospitals in Lancaster, Newcastle, Leicester and Warwickshire, the roof of this operating theatre required a new waterproofing system.



Queen Elizabeth Hospital, Edgbaston

The dishwasher area of the hospital required a full refurbishment as the existing felt roof was causing problems through leaking in three separate areas. Consequently the client required a protective system for roofs and, following the successful application of a Sterisept hygienic system which had been used for internal application to the hospital, a Sika Liquid Plastics coating was specified.



West Suffolk Hospital

Sika Liquid Plastics has specified and supplied a roof upgrade solution for West Suffolk Hospital to renew the waterproofing membrane on multiple areas of the hospital campus and create a gradual pitch to aid drainage while enhancing the building’s thermal performance.



Royal Hallamshire Hospital

The original asphalt waterproofing laid on the roof of this hospital many years ago was starting to show signs of distress, and the constant ingress of water as a result was becoming a major concern.

York NHS Trust Headquarters

Short description

It was discovered that the original rock asphalt roof and balcony of the York NHS Trust headquarters were in a very poor condition and in desperate need of repair. Located just next door to Scarborough Hospital, the office building would have to be in constant use during the refurbishment, due to the vital nature of the services its staff provide. This presented a challenge for Sunderland-based roofing contractor, Group Tegula, working alongside the Sika Liquid Plastics refurbishment team.
