SIKA Liquid Plastics – Keeping the fight against COVID-19 watertight

DVC Roofing are Quality Assured contractors for SIKA Liquid Plastics. In addition to our extensive product knowledge and experience, we have the right team to complete the project. Crucially we are following strict government guidelines and current heightened health and safety measures.

About Client


DVC are proudly carrying out maintenance works at the Sir David Jack’s Research and Development site using SIKA Liquid Plastics. Located in London Ware, and owned by pharma giant GSK, the R&D site has significant importance in the UK supporting the global response to COVID-19.

Works will ensure continuous operation of the site and protection of the advanced sensitive equipment within the R&D labs whilst making the building watertight.

From Client

In total, GSK employs over 2000 people across manufacturing and R&D facilities in Ware, Hertfordshire, UK. GSK – one of the world’s leading research-based pharmaceutical and healthcare companies – is committed to improving the quality of human life by enabling people to do more, feel better and live longer. For further information, please visit us.

The Challenge of the Roof

Firstly a visual and physical on-site survey covering an area of 5000m2 composite steel sheets and asphalt identified the roofs condition. Our team inspected the site using multiple technologies, core sampling and moisture probe analysis to pinpoint the reliability of the existing waterproofing.Clearly, the waterproofing of the roof had reached the end of its service life, and water had infiltrated to the underlayer. The integrity of the roof is business-critical for GSK, particularly as equipment within the building needs to be protected from water ingress or a damp and humid environment.

The Solution

In response to the requirement of a timely solution, and with minimum disruption, DVC introduced Sikalastic® to compile a full specification to suit the client’s needs.

Sika Liquid Plastics’ Decothane system was proposed, a system which meets especially high industry standards, is relatively quick to install, virtually odourless, and cost-effective.

The solution includes encapsulating an area of 5000m2 of SIKA Liquid coatings to the existing roof sheets. The SIKA Liquid Plastics solution will eliminate the risk of leaks from an area of the roof that had previously proved problematic. Sikalastic® Decothane provides the ideal waterproofing, protecting the building from unpredicted UK weather. A perfect option enabling a low-key project with no disruption!

GSK is an ongoing project; we are halfway through and on target for completion. The business-critical nature of the site has so-far created challenges in itself. We are working to strict 2-meter distances and to GSK’s essential works guidelines. Notwithstanding these added difficulties, DVC is managing the process on-site with the highest levels of quality. Most importantly, with limited disruption to the everyday operation of the R&D labs.


Without a doubt the Sikalastic® Decothane provides a robust solution. Importantly the waterproofing comes with a 20-year guarantee and gives GSK peace of mind against water ingress.
