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.
