Flexible, durable surface material used for expansion of Yorkshire facility
Sika's Type 'S' mebrance was used to waterproof the roof at Fieldhead in Wakefield
Sika-Trocal’s flexible, durable Type ‘S’ membrane provided the ideal waterproof solution for a large and complex roof installation at a new health facility.
Completed in two phases, the extension to Fieldhead in Wakefield, West Yorkshire – run by South West Yorkshire Partnership NHS Foundation Trust – was built to provide additional patient accommodation.
The project’s first phase involved the installation of Sika-Trocal’s Type ‘S’ waterproof system across a 2,000sq m area of roofing.
The 2mm-thick, mechanically-fastened, single-ply membrane’s adaptability was ideal for the task, as it had to cover a number of intricate roofing details.
Selected by Interserve Construction, FCB Roofing installed the slate-grey Type ‘S’ membrane to 400mm-thick tapered insulation.
This accommodated the roof’s intricate multi-directional design and its various falls.
For the 2m verticals and curved areas, Sika-Trocal parapet trim provided a uniform finish.
Waterproofing work on the project’s second phase presented a different challenge for installers, with the entrance’s 2,000sq m fan-style, five-tier roof.
Again, the Type ‘S’ system’s malleability proved crucial in overcoming an application of such complexity.
Tony Comrie, contracts director at FCB Roofing, said: “I don’t know of any membrane that would have been suitable for this project, other than the Sika-Trocal Type ‘S’.
“It helped simplify a challenging installation and its flexibility was essential to the waterproofing being finished on time and to the highest standard.”
