The AlphaTauri driver was pitched into a spin at the flat-out Maggots left-hander last weekend, and ended up having a big impact with the originally uncovered barrier on the outside of Becketts.
While it is an unusual place to crash, the FIA is taking no risks and, ahead of the 70th Anniversary Grand Prix, has begun installing extra protection as can be seen in the images.
In a note sent ahead of the race weekend notifying teams of track changes, F1 race director Michael Masi said: "A tyre barrier approximately 36m long has been installed at the rear of the Turn 11 run-off area."
