Cracks in the screed let moisture penetrate the reinforcement and led to corrosive damage on the load bearing construction of the Olympic Ice Sport Centre's entrance area in Garmisch-Partenkirchen. A quick refurbishment was needed to ensure that the floor would be finished in time for the start of the ice hockey season and for the G7 summit in 2015.
As the client, Garmisch-Partenkirchen municipal utilities decided on a solution using Triflex ProPark. The maintenance-free waterproofing system is very robust due to the high-friction plastic used and is able to withstand mechanical loads in the long term. The liquid applied waterproofing is also resistant to extreme weather conditions such as UV and IR radiation and de-icing salts. Thanks to the non-slip properties, the visitors to the stadium can tread safely on the floor. The fleece-reinforced system with a PMMA base features full-surface adhesion which means that no water can creep in. Complicated details are integrated homogeneously into the seamless and jointless waterproofing. The liquid applied waterproofing cures in no time at all. The General Building Supervisory Authority Test Certificate (abP) and the OS 10 classification are testament to the safety of the liquid applied waterproofing.
In a first work step, the contractors processed the existing substrate by removing the old screed and refurbished the isolated damages to the reinforcement. They supplemented the reinforcement in the statically relevant components and the overhanging load bearing consoles. A Garmisch-Partenkirchen-based planning bureau for structural engineering and fire safety initially undertook structural analysis. The newly applied screed was ground in order to ensure optimum adhesion of the liquid applied waterproofing. Then the contractors applied the waterproofing system Triflex ProPark in version 2 to the balcony surface. For this purpose they initially primed the surface with Triflex Cryl Primer 287. Afterwards they waterproofed all details and penetrations with Triflex ProDetail. The refurbishment experts applied Triflex ProPark to the surface and integrated Triflex Special Fleece. Triflex Cryl M 264 in the colour traffic grey is used as a non-slip wearing layer. The contractors also sealed the steps including the stair edge protection with the liquid applied waterproofing.
