«Shells» of the Sydney Opera House

Weight of the Sydney Opera House, situated on Bennelong Point, is 161 000 t. The giant building is supported on 588 concrete piers sunk as much as 25 m below sea level.

Upon special request the azulejo gloss white and matt cream ceramic tiles was shipped from Sweden, thereby the «shells» have snow-white look regardless of season and weather and season. Despite the manufacturer’s proclamation of innovative dirty-proof coating, the roofing used to be cleaned few times per year.

The unique architectural idea lies on curving fan-like roof structures made of concrete. Engineers applied epoxy resin to join the roof beams.

GEOFIP-KB6 geopolymer based adhesive is an effective alternative to epoxy resins, which allows binding the elements of mineral structures causing no adverse health effects during application.
