Work is being carried out on Shanghai's sinking circuitThe real reason behind the FIA’s decision to delay granting homologation to the Shanghai circuit has now become apparent: the track surface is sinking in several places.

And with the next event at the Hermann Tilke circuit pencilled in for a provisional April date, work is furiously underway to have everything rectified ahead of the FIA’s final inspection in March.

Local race organisers have now confirmed that the track surface is suffering from subsidence at three corners: Turns 1, 8 and 14.

“Fixing it] should be no problem,” Yang Yibin, the manager of the race’s promoter told the Shanghai Daily.

“We’ve communicated well with the FIA, our plan has been approved and the grand prix will be on time.”

The circuit is laid out on reclaimed swampland, with much of the elevation change artificially created using polystyrene “complex materials”.

“Subsidence is normal because of the soft soil in Shanghai, which the circuit was built above,” Yang added.

“Because some parts of the circuit are on the ground while some parts are not, as time goes by it’s normal for some subsidence,” added the circuit’s engineering manager, Sun Liang.
