The Elbphilharmonie concert hall stands as a remarkable architectural and cultural landmark, constructed with the aid of cutting-edge sealing and bonding solutions provided by Sika.
Project Overview
Participants
- Owner: Elbphilharmonie Hamburg Bau GmbH
- Architects: Herzog & de Meuron, Basel
- Contractor: Hochtief Solutions AG, ADAMANTA GmbH
Project Requirements
The renovation of the existing warehouse involved reinforcing the historical brick facade and adding 650 new concrete piles to support the substantial weight of the Elbphilharmonie. Repurposing the warehouse included creating parking, restaurants, rehearsal spaces, and storage areas. Additionally, a spacious plaza of approximately 3,100m² was constructed to connect the restored warehouse with the new building component.
Sika Solutions
Concrete Technologies
- Sika® Watertight Concrete System was used in both the basement and terraces, offering a secondary defense against water penetration.
- Sika admixtures were added to 1,000 m³ of Sika® Watertight Concrete to prevent water ingress.
- Sika® Silicoll SL ultra-fine pozzolanic concrete additive optimized the durability of the concrete in the plaza foyer.
Corrosion Protection
- The steel stair balustrades received an anti-corrosive finish using the SikaCor® EG system, ensuring long-term abrasion and impact resistance.
Sealing and Bonding
- Sikasil® SG-500 and Sikasil® IG-25 HM Plus sealants were employed for the glass facade, providing structural integrity and weather resistance.
- Sealant solutions from Sika were used for floor joints in break rooms and stairwells, ensuring airtightness and durability.
Roofing Systems
- The roof area, consisting of eight concave surfaces, utilized Sarnafil® TS 77-20 E multi-layer polymeric membrane for waterproofing.
- Sarnafil® TG 66-18 FPO membranes were employed for roof junctions, offering homogeneous welding and superior waterproofing.
