New lawn...

Hi all
Had a new lawn laid today. The ground had been covered in gravel so already had that removed. The agreement with the gardener was that he'd rotavate in any gravel left and add topsoil to lay the turf on. I've just pulled one up to discover this... (see photo).I'm assuming that the turf won't root?
