Project Description
The redevelopment of the iconic Hampden Park Stadium for the 20th Commonwealth Games in Glasgow was lauded as a key achievement during the build up to the event held in the summer of 2014.
The stadium, usually home to the Scottish national football team, was selected as the cornerstone venue for the games, hosting all the flagship track and field events on an IAAF approved track, as well as the opening and closing ceremonies.
It has been well publicised that the stadium, in its usual format, didn’t allow space to integrate the running track and infield games areas. To allow construction of the required facilities, an innovative solution involving the construction of a podium deck was designed. This deck increased the floor level within the stadium by two meters and created a sufficient floor area to allow the construction of the running track and in-field.
The Challenge
Integrating a drainage layer within the sports field construction was a key challenge for the design team. Efficient drainage of sports facilities is essential to allow the events to continue, regardless of the weather. Traditional drainage techniques requiring free-draining stone layers were not suitable for this scheme, adding both too much weight on the podium deck and too much depth to the overall construction.
The Solution
The solution chosen by the project design team was Pozidrain 7S250D from ABG. Pozidrain is a high performance drainage composite comprising a cuspated core with impermeable back and integral geotextile filter fabric. The fabric allows the free flow of water into the free draining void formed by the high strength core. The result is a highly efficient drainage system at a fraction of the depth and weight of a stone drainage layer. Pozidrain was installed across the entire podium deck area, before being covered over with the sport pitch build-up.
