Madring is preparing for its Formula 1 debut at the 2026 Spanish Grand Prix with a bespoke safety system inspired partly by the barriers used on American ovals and in NASCAR. The new Madrid circuit will become the first venue to use this particular combination of safety solutions at its heavily banked La Monumental corner.
La Monumental is one of the defining features of the new Madring layout. The corner stretches for 550 metres, features banking of 13.5 degrees and a 24% gradient, making it one of the longest and most demanding banked corners on the modern Formula 1 calendar.
Madring’s La Monumental already impresses F1 drivers
Drivers have already expressed appreciation for this part of the circuit. Charles Leclerc, after taking part in a Filming Day at the venue in July, described it as “one of the most iconic corners of the season”.
Formula 3 drivers have also highlighted the unusual challenge presented by Madring. Following a recent test, Freddie Slater described it as “one of the most fun circuits for a single lap”.
Building La Monumental from what had originally been flat ground required a substantial engineering effort. IFEMA reused excavated soil to shape the banking before asphalt was laid at extreme angles.
With speeds of up to 240 km/h expected through the section, a dedicated safety solution was required. That responsibility was entrusted to motorsport safety specialists Geobrugg.
NASCAR-style SAFER barriers form part of Madring safety system
Geobrugg, which already supplies debris fencing to several circuits on the Formula 1 calendar, including the Red Bull Ring, Silverstone, Miami, Las Vegas, Jeddah, the Hungaroring and Spa-Francorchamps, has developed what is described as a world-first combination for Madrid.
The system integrates Geobrugg Mobile Debris Fences with DELTABLOC concrete safety barriers and the SmithFence SAFER barrier, which uses steel and foam to reduce impact energy.
The mobile debris fencing is positioned at 90 degrees relative to the banking. For the first time, anchoring pins have also been used on an inclined corner to secure the concrete barriers directly to the asphalt.
This prevents the barriers from moving during an impact and provides a stable base for the SAFER barrier mounted in front of them.
Jochen Braunwarth, Geobrugg’s director of motorsport solutions, explained the principle behind the system: “As in NASCAR oval racing, the cars will slide along the SAFER barrier in the event of an impact, dissipating energy and preventing them from bouncing back into traffic. This tailor-made solution is fundamental for La Monumental, where F1 cars will reach some of the highest speeds seen on a street circuit while negotiating the corner.”
More than 3,300 concrete barriers produced for Madring
More than 3,300 concrete safety barriers were manufactured to support the high-strength steel mesh panels used for the debris fencing.
To meet the construction timetable, Portuguese company Vialsil was brought into the project. The company produced the blocks at a rate of 35 per day until work was completed at the beginning of June.
Francisco Portela of Vialsil explained: “We made a significant increase in production capacity to meet the aggressive 14-month construction deadline. In addition to manufacturing the blocks, our team handled the assembly and installation of the barriers directly with Geobrugg.”
Madring introduces further F1 safety innovations
Geobrugg has also introduced bespoke safety solutions in other complex areas of the new Madrid circuit.
At the braking zone for Turn 20, a shortened version of the Mobile Debris Fence has been used to improve visibility for the drivers. A specially designed opening in the pit wall provides access to the grid for marshals, officials and team personnel, while also making it easier for photographers and television crews to work around the area.
In the weeks before the race, Geobrugg worked directly with F1TV production teams to create 19 flexible camera openings and 60 dedicated cut-outs for photographers.
Each opening uses high-strength mesh secured with stabilising struts and tension bars. The design allows close-up filming at speeds of up to 210 km/h without compromising the structural integrity of the safety system.
Sustainability also central to Madring circuit design
Sustainability has also been an important element in the design of Madring. The circuit includes a 5.5 MW solar installation intended to provide the venue with green energy.
As part of that approach, Geobrugg has used carbon-neutral-impact concrete barriers in the paddock area. These were developed in partnership with Austrian road-safety specialists DELTABLOC.
The Madrid event adds a completely new venue to the 2026 F1 season, with Madring hosting the Spanish Grand Prix as Formula 1 introduces a new street-style challenge in the Spanish capital.
Jochen Braunwarth concluded: “This project demonstrates how street-circuit engineering can deliver breathtaking speed and spectacle while at the same time maintaining the highest FIA safety standards.”
