Hull, United Kingdom

Flat Roof Project Requirements

Forming part of an £8 million facelift, the 13 storey Hull Royal Infirmary required new windows, concrete repairs around the entire building, resurfaced exterior walls and a new roofing system.

For the 1000m2 roof, client Hull and East Yorkshire NHS Trust turned to leading waterproofing and roofing specialist, BriggsAmasco who had extensive experience applying the Sika Liquid Plastics roofing system.

In keeping with the project’s design, the roof was installed with a fully built-up Decothane Liquid Applied Warm Roof system. A vapour control layer was applied with 130mm of Decotherm insulation and Gamma 20 waterproofing on the surface, with non-slip walkways.

"The performance of the new roofing system is a step above the previous one. Now that it has been upgraded to comply with building regulations, it is more efficient in terms of heat loss/gain. As with all of our systems, the benefits are that it is a cold application which is very effective in sealing up to detail work and offers a truly seamless finish to the roof."
