Stephen Perse Foundation Rooftop Multi-Use Games Area, Cambridge
'Cambridge's First Rooftop Multi-Use Games Area'
The Scheme
The Stephen Perse Foundation aimed to enhance their learning spaces and deliver cutting edge facilities for science, technology, engineering, mathematics (STEM) and sport by installing ‘Cambridge’s first rooftop multi-use games area’ on top of their new Senior School in Cambridge.
The Solution
SELSports designed and installed a 620m2 state of the art rooftop sports facility, incorporating an innovative lightweight subbase drainage system comprising specialist shallow drainage cells with a high void ratio, allowing large volumes of water to freely drain from the surface into the subbase, where it is released through a restricted rainwater outlet.
There was a total of 4 rainwater outlets located within the pitch area. These outlets were housed in SELSports fabricated access chambers with recessed manhole lids. Using a wet pour shockpad, SELSports installed discreet and safe access chambers within the pitch area.
A prefabricated shockpad was installed directly on the drainage layer as part of the synthetic turf system, reducing point loading and providing a shock absorption layer. The system was finished off with a 20mm sand dressed synthetic grass with netball and 5-a-side football line markings.
The ability to store large quantities of water within a shallow, lightweight pitch construction, significantly reduces the risk of flooding during heavy rainfall, and reduces the need for large water attenuation tanks at ground level.
