Creating a green roof
Etele Plaza has been rated as “Very Good” according to BREEAM criteria (a voluntary sustainability rating system for buildings developed in the UK), a requirement of the client, thanks to a reduction in light pollution, the use of durable and recycled materials and the presence of “green” surfaces at the entrance to the shopping centre and on the roof.
The green roof needed to have a really efficient waterproofing system. Therefore, the contractor decided to opt for Polyglass solutions, a subsidiary of Mapei Group, POLYPRIMER bituminous primer was used to promote adhesion of the membranes applied afterwards. FLEXO S6 PREMIUM waterproofing membrane was then applied on the surface. ANTIRADICE FLEX P was also applied to provide further protection: an elastomeric membrane ensuring high resistance to root penetration. Its special compound creates a chemical barrier, ensuring the membrane delivers perfect watertightness and resistance to aggressive chemicals and puncture by plant roots. As for other roofs, the products used were MAPEPLAN T M 18 BROOF (t2) - a synthetic FPO/TPO membrane, certified to the requirements of the external fire performance standard - and MAPEPLAN T METAL SHEET, used as press-formed finishing profiles.
Installation of ceramic tiles
The floor substrates in several areas were levelled off with NOVOPLAN MAXI cementitious mortar, except in the bathrooms where PLANEX HR moisture-resistant, self-levelling mortar was recommended. Most of the ceramic tiles were installed with ADESILEX P9
improved cementitious adhesive. KERAFLEX MAXI S1 cementitious adhesive was chosen for the service corridors and bathrooms, while in the sales areas exposed to intense footfall, KERAFLEX EASY S1 was used, which is particularly resistant to heavy loads. The joints were grouted with KERACOLOR FF FLEX cementitious mortar, which is distributed on the Hungarian market by Mapei Kft.
