I have honestly never seen anything like this in my entire life. Watching the structural engineering magic that took place at the SoFi Stadium to prepare it for the World Cup completely blew my mind. We are talking about arguably the most technologically advanced, hyper-modern multi sports venue on the planet. A $5.5 billion indoor-outdoor masterpiece in Los Angeles owned by Arsenal's owner, Stan Kroenke. SoFi Stadium is owned by the billionaire real estate developer and sports mogul through his development and holding company, Kroenke Sports & Entertainment (KSE). This masterpiece features a massive translucent roof and a mind-blowing, 70,000-square-foot double-sided 4K "Infinity Screen" hanging over the field. But did you know that despite all this luxury, the stadium was never actually built to host international football? An NFL field is significantly narrower than a regulation FIFA pitch, meaning SoFi was physically too tight to fit a World Cup game. To solve this, engineers pulled off the ultimate flex over the last two months. They literally ripped out and reconfigured entire steel sections of the lower bowl seating in the corners just to widen the ground floor. Then, because FIFA strictly bans artificial turf, they had to lay a massive, temporary natural grass pitch right on top of the existing synthetic NFL turf. They laid down specialized Permavoid drainage and vacuum-powered ventilation crates, covered it in sand, and trucked in premium, refrigerated Kentucky bluegrass sod grown all the way in Washington state. Because the roof blocks out a lot of natural sunlight, they are literally using massive, wheeled LED grow lights to keep the grass alive and growing inside the arena. The coolest part about this entire engineering wizardry is that it is completely temporary. As soon as the World Cup is over, they will roll up the natural grass, put the corner seats back in, and revert the stadium right back to its standard synthetic turf for the LA Rams and Chargers NFL season. It is pure, high-stakes architectural magic What makes this SoFi Stadium conversion even wilder is that the entire project isn't just about putting down dirt and grass, it is a full-blown engineering miracle. Because the stadium was originally built for the NFL, the new World Cup pitch actually sits about 30 inches higher than the normal American football field level. They had to raise the entire playing surface to make it align with the newly modified, retractable steel corners. And get this about the tech: the stadium is built 100 feet below ground level because it sits directly in the flight path of LAX airport, meaning players are literally playing in a massive, high-tech canyon. Because it's so deep underground and the roof is a closed canopy, the natural grass has zero chance of surviving on its own. The pitch relies on a subsurface "vacuum-powered" ventilation network that literally pumps oxygen directly into the grass roots from underneath, while an automated, data-driven IoT sensor grid monitors the moisture and soil behavior in real-time. Even the crazy 2.2-million-pound "Infinity Screen" hanging overhead plays a structural role. It is so heavy that engineers actually use its massive weight to anchor and hold the stadium's translucent roof down during high-velocity windstorms. I am in tears how that ₦210T ($154B) that the former NNPC boss allegedly diverted could fund about 30 units of this masterpiece. We could legit have one of this stadium in almost every Nigerian state. It proves Africa’s (esp Nigeria's) problem isn’t a lack of wealth, but a tragic lack of leaders with working brain cells. It’s exhausting.

And this is special, because...? Wembley uses an active system that's over triple the speed (well over 15 inches, rather than 5, per hour). Santiago Bernabeu in Madrid has a permavoid system AND a retractable pitch to do the drying beneath the surface. Very few mushy pea left.

And away goes the permavoid from Charlotte! 3rd of 12 Trucks!

They’re installing a permavoid irrigation system which is basically crates which will collect water under the pitch and then reuse it to water the pitch and training one. Mike Baggaley had a bit about it in his last newsletter.

leaguetwt is just permavoid culture 50 unfunny saskio like tweets riot kassadin and every 3 months i make a random tweet like every other except it gets reach and i get crucified for it for like 4 days then the cycle repeats

Now, the grass. A hybrid of artificial fibers woven into natural grass grown on a plastic base (like EPL). These pics are from the '24 Copa install, but was a test run of the grass, permavoid, plumbing & grow lights. The surface was a big hit. 10/11 -

here's a closer look - on top of all of that gravel/dirt will be a Permavoid layer, then lots of sand and then grass. Plus, irrigation (yes, full sprinklers!), ventilation and drainage systems. Pumps & plumbing installed in '24 & left for World Cup. 9/11

Permavoid 85s base for the FOP and Permavoid 150 double stacked around the FOP perimeter! We will be adding rootzone to the FOP for grass to sit on later on

Nuevo Estadio el Campín Sencia ya Tiene piloteadora para obras Detalles técnicos y con evidencia del sistema PERMAVOID youtu.be/krnaG1u-iWg #NuevoVideoVIDJCB #VIDJCB #SinGramaNoHaySencia

Se ha instalado Permavoid en el suelo del estadio SoFi, debajo de su campo de fútbol temporal. Encima del "andamio" se aplica la base para grama híbrida. Todo lo demás es humo y chambonadas

Lo que ocurre en el Campín con cada concierto: 20 mil personas en grama aplican una presión de más de 1500 toneladas que aumentan con cada brinco. Debe mantenerse cada año reemplazando la sub-base que se compacta. Este proceso toma 3 meses. ideal permavoid

Kegelmishap is just a fucking creature. Easy permavoid

Wat ik mis in dit artikel is de vraag over de ligging van het veld. Er wordt altijd gezegd dat voor een ideaal veld, dit eigenlijk een kwartslag gedraaid moet worden. Hoe kijkt Permavoid aan tegen de ligging, of hebben ze met hun systeem de oplossing in handen? #nacpraat

El SoFi ya tiene ese sistema (permavoid o algo así) Lo instalaron para la copa de naciones de este año (marzo) y en abril lo quitaron jaja. Se supone que para inicios de 2026 lo volverán a instalar, y ya será en todos los estadios mundialistas de 🇺🇸
