PROJECT OVERVIEW

As part of a wider school refurbishment project, Sussex Asphalte were responsible for the mastic asphalt coverings. The project involved stripping the 250m² of existing defective coverings down to the flat concrete slab, and laying new asphalt in two coats, finished with 2 coats of solar reflective paint. All in strict accordance with the IKO specification. Christ Hospital school is a prestigious listed building that was founded in 1552. Christ's Hospital was the result of the foundation by Henry VIII and confirmed by Edward VI, assisted by Nicholas Ridley, Bishop of London, and Sir Richard Dobbs, Lord Mayor of London. Due to the heritage status of the building, mastic asphalt was specified for the roof covering

PROJECT CHALLENGES

The stripping of the existing mastic asphalt coverings exposed various challenges. Most notably, the strip itself was made extremely difficult due to the multiple layers of varying materials used to coat and overlay the area over the years. Upon removal, our operatives uncovered multiple layers of mastic asphalt, felt and liquid roof coverings. In addition to this, the removal of the existing waterproofing exposed electrical cabling feeding the lighting below. Additional care had to be taken when breaking out the existing build up to ensure no damage to the conduit or cables within. Operatives also had to be cautious when laying the new asphalt, ensuring the conduits were suitably protected to avoid them melting from the residual heat of the fresh mastic asphalt covering
