2026 FIFA World Cup- What is Permavoid and how is it used in football stadiums?
- Permavoid is a geocellular drainage system laid as a sub-base beneath sports turf. At MetLife Stadium it sits under the Tahoma 31 bermudagrass rolls installed for the 2026 World Cup, preventing waterlogging and maintaining root-zone air movement.Source: event
- What is Permavoid and how is it used in the World Cup?

- How does drainage work under a World Cup pitch?
- MetLife Stadium uses a Permavoid geocellular sub-base — a honeycomb structure creating void space for water and air — beneath the Tahoma 31 bermudagrass surface. This manages waterlogging at a stadium that sits in a river meadowland.Source: Lowdown
- Why is MetLife Stadium prone to waterlogging?
- MetLife Stadium sits in a river meadowland in East Rutherford, New Jersey, making drainage a critical concern for the Tahoma 31 turf surface and Permavoid sub-base installed for the 2026 World Cup final.Source: Lowdown
Background
Permavoid is a geocellular drainage and aeration system used as a permeable sub-base layer in professional sports turf installations. It appears in the MetLife Stadium 2026 World Cup pitch build: the Permavoid cloth is part of the stadium's sub-base, laid beneath the Tahoma 31 bermudagrass rolls to ensure rapid drainage and root-zone aeration.
Permavoid panels are manufactured in a honeycomb geocellular structure that creates void space for water and air movement while supporting the load of the turf and players above. The system is used at premier sports venues globally to manage waterlogging — an acute concern at a stadium like MetLife that sits in a river meadowland in East Rutherford and hosts outdoor events year-round.
