Titan Flooring was the main flooring contractor for the £27.5m development, which includes the new six-storey Oastler building that will house the University’s Law School and part of the School of Music, Humanities and Media. The building has a range of environmental features which have helped it achieve BREEAM Excellent status.
Challenging site conditions
The project provided Titan with some challenging site conditions and Bostik’s technical expertise and ability to quickly tackle any issues on site were instrumental in winning the work.
One of the biggest challenges encountered at the university was uneven subfloors. This was more prevalent in the circulation areas of the building, so Bostik advised that the flooring levels should be brought back to an acceptable tolerance by applying Screedmaster Deep in a controlled manner.
The versatility of the Screedmaster Deep self-levelling compound allows for application between 5mm to 50mm in a single step. It can also withstand foot traffic in as little as 90 minutes, meaning the project’s timescales would not be compromised.
Where Screedmaster Deep was required to raise the floor levels, an even film of Bostik’s Screedmaster One Coat Membrane was first applied to control the moisture levels within the subfloor. Screedmaster Epoxy Primer was then applied to improve the bond between the subfloor and levelling compound. Epoxy Primer is a two part, solvent-free, water dispersible primer that’s ideal for use when applying smoothing compounds above 10mm in depth.
Due to the nature of the calcium sulphate screeds used in other areas of the site, it was necessary to apply a diluted layer of Epoxy Primer prior to the application of the self-levelling compound. This provided a high-performance barrier to enable the two materials to work in combination. In areas where a traditional cement sand screed was present, Bostik specified the use of the Screedmaster One Coat Membrane, followed by its multi-purpose Universal Primer.
