Take a closer look at this project at Tottenham Hotspur: 

We are extremely proud to have collaborated with Hewitt Sportsturf to provide Tottenham Hotspur with an industry leading playing surface considered to be one of the greatest football pitches in the world. Tottenham Hotspur aimed to create a home for generations to come, and one that is exceptional.

The exceptional New White Hart Lane incorporated the scintillating retractable football pitch, allowing the football club to host Premier League football matches and NFL matches on separate dedicated pitches, in the same stadium. Permavoid technology was not only incorporated to facilitate this great innovation, but also to maintain the finest quality playing surface for both the natural grass Premier League pitch and artificial turf NFL pitch.

We place a high priority on creating solutions that meet the best sustainability standards.


What have we done?

Artificial NFL Pitch
Permavoid 85 units were installed directly on a concrete slab, between the tracks of the retractable Premier League pitch, to form the base for the synthetic turf NFL pitch. The Permavoid units created a consistent base with the ability to attenuate a 1 in 100 year + 30% storm event, with a restricted discharge rate. Two layers of Tarmac were installed directly on the Permavoid, before the shockpad and artificial turf were installed.

Tottenham Hotspur aimed to create a home for generations to come, and one that is truly exceptional. 


Stadium Roof and Car Park Attenuation

The vast stadium roof and large car park required a considerable amount of rainwater attenuation volume in the form of modular plastic attenuation tanks. Due to space restrictions, all attenuation tanks were located under heavily trafficked areas. As such, Permavoid units were selected for the attenuation tanks due to its extremely favourable strength characteristics and versatility.
