Sika provided the rapid, watertight roof solution for a new building within a firefighting hub.

Flat Roof Project Requirements

The Scottish Fire and Rescue Service, East Service Delivery Area Headquarters in Newbridge, Edinburgh has been equipped with a new training centre. The 800m2 ‘TSB’ building required a waterproof roof system that not only offered long-term protection against the elements, it needed to be quick to install and flexible enough to accommodate a number of roofing details. Sika-Trocal’s fully-bonded SGK membrane system proved more than ideal for the task.

Sika-Trocal Solutions

Main contractor, Robertson Construction, working on behalf of client Scottish Fire and Rescue Service, appointed Reid Roof Ltd to carry-out the flat-roof’s installation. Work began in June 2018 and initially involved applying Sika® S-Vap 5000E SA, a multi-layer, self-adhesive air and vapour control layer, to the low-pitched roof’s concrete substrate. Comprising polymer-modified bitumen, glass-fibre mat reinforcement and an aluminum foil as top layer, S-Vap’s superb strength enables simple, rapid installationand exemplary, airtight roof construction. A layer of Sika-Trocal INNObond, a durable, easy-to-apply, high-performing insulation board, provided a quality thermal base for the SGK membrane.

The reinforced PVC waterproof membrane offers a durable solution for warm and cold roof constructions. As well as supplying high tensile strength,Sika-Trocal® SGK provides outstanding weathering and excellent flexibility in cold temperatures, which along with its easy-fit benefits; make it the ideal membrane for exposed flat roofs. The light-grey membrane was affixed using the Sika-Trocal® spray-adhesive range. Time and cost-effective, the range - which includes Sika-Trocal®C400 and C250 - is also kind to the environment. It contains fewer solvents than poured-applied adhesives and creates less material waste. Once used,a canister can be decommissioned as scrap metal, making it a recyclable material.Sika-Trocal® SG, a 1.5 mm multi-layer, synthetic roof waterproofing sheet, provided the aesthetically-pleasing solution for the roof’s various vertical upstands.Brian Hartie, Contracts Manager at Reid Roof Ltd, said: “Sika makes quality products, and its SGK system is no exception. Its flexibility in being able to absorb some intricate roof details was crucial to the project’s success. It’s a superb, rapid-apply system.”

The TSB building’s roof installation was completed in August 2018. Thanks to the flexible and rapid-apply properties of the Sika-Trocal® SGK system,contractors were able to meet the client’s strict deadline and supply a roof that will provide long-term protection for the depot’s new training facility for many years to come.
