About 4,000 sq m of Elmich VersiDrain 6P was installed recently at the rooftop of a new 2-storey bus park with rooftop playcourts at the United World College of South East Asia (UWCSEA) at Dover Road, Singapore. UWCSEA is an independent, non-profit International school offering full primary as well as secondary education in Singapore. The school’s main campus at Dover Road is the largest of the 13 United World College (UWC) schools, a movement founded by the German educationalist Kurt Hahn with the mission of bringing together students from all over the world and developing them as global citizens.
VersiDrain 6P was used to prevent unsightly efflorescence and to minimise surface finish cracks on the rooftop when dissolved salts are trapped under the screed. The modules are positioned between the structural slab and topping screed as a separation layer, which creates a drainage and ventilation cavity that allows trapped water in the screed to escape.
