Ryhope Hospital

The Pride development is a £60 million investment which includes a new 122 bed hospital being built on the former Ryhope Hospital site in Sunderland. Laing O’Rourke, the main contractors of this project, specified Polyroof waterproofing systems for the flat roof areas.

Barclay Roofing Ltd carried out the works, having previously worked with Laing O’Rourke on the 2013 Roofing Award Winning Durham Gateway Project.

The Solution

The roofs were of a complex nature and involved many details such as vents, level changes, handrail abutments, plant supports, protrusions, stanchion blocks, and parapet walls. It was essential that these details could be waterproofed in the most effective and rapid way possible. Protec, being liquid-applied, was dressed onto the upstands of the details without the need for lengthy and complicated ‘patching’ work, creating a totally seamless interface between the details and the flat roof membrane.

The client required designated, permanent walkways for maintenance purposes. Quartz Sand & Polyfinish was used to create a durable and hard-wearing anti-slip finish, without the need for costly ancillary walkway systems. The system is capable of withstanding heavy foot traffic and is impact resistant meaning the client had peace of mind that the walkways can be used without the risk of damaging the waterproofing integrity. Some of the roof areas are to be covered with a green roof system. The waterproofing membrane that was used therefore had to be highly durable, lightweight, fully root resistant and maintenance-free. The Protec System meets all the criteria for use with green roofs and was specified as the ideal solution for the green roof areas.

It was essential that health & safety and hazard risks were kept to an absolute minimum during works. Being cold applied and low in VOC content, Protec was able to satisfy the stringent requirements of this aspect of the project.

Due to the size of the roof areas, structural expansion and contraction movements had to be considered. Ideally the client wanted a waterproofing system that could accommodate these movements without the need for any additional and potentially costly modifications such as expansion joints. Protec is specially formulated to be highly flexible whilst also maintain its durability and hard-wearing properties.
