We’ll always find a way – or two.
Sometimes unforeseen challenges can pop up in projects. In those moments, it’s critical to find quick and effective solutions.
New residential quarter for all kinds of needs
A new project that started in 2018, on the site of the former Riedenburg barracks in Salzburg, has begun taking shape. The project includes 22 new apartment complexes with separate units, and will meet a variety of living needs for families, single parents, seniors and first-time renters. Previously closed off by a high wall, the 35,000 sqm grounds are accessible by foot or bike from every direction. The attractive Quarter will incorporate a 5,000 sqm park and play area that is accessible to the general public, a kindergarten, and spaces for medical practices and small business - including restaurants and caterers. The first apartments have already been moved into.
Modern mobility concept
The mobility concept provides underground parking for 300 cars, in a garage with multiple entrances and exits. Another 20 parking spaces will be available above ground for deliveries and visitors, with an additional 830 bicycle racks and two spaces with charging stations for electric cars.
Drainage issues with underground parking
The underground parking garage proved to be one of the biggest challenges. According to the original planning, outlets were to be fitted at specific points, in order to drain the weather-exposed surfaces. But as the parking garage is beneath the surface, this would have required openings at several points in the ceiling.
BG-Graspointner’s support technician, Markus Unterberger, explains:
Solutions sought and found
Unterberger, along with with Albert Eberdorfer, the General Manager of Geologie-Wasser-Umwelt GmbH, devised an alternative solution:
After working out hydraulic calculations for the jointly devised solutions, we decided to use wider channels in specified areas to get the necessary hydraulic capacity, and were able to connect adjacent surface areas to the main channels. Another problem was the lack of a gradient in the playground area. Our solution was to use particularly deep channels, and concrete wedges to create an artificial slope. Our FILCOTEN® HPC channel material proved to be ideal. Thanks to its mineral properties, FILCOTEN® HPC bonded securely with the concrete wedges, and ensured sufficient construction height. All drainage water now flows through outlet lines into underground seepage systems, and dirty water from the subterranean garage and parking lot areas is discharged via the sewer system.
Eberdorfer was happy with the results. He was especially delighted, however, with the environmental benefits of BG drainage systems, and believes sustainability should be taken into consideration whenever possible.
BG-Graspointner Sales Consultant Gottfried Graspointner labelled the project a success, attributing the fruitful cooperation to multiple factors:
