I usually prefer layering fig by tossing some soil over the limb(s)... They root easily... And soil layering is certainly easy.
Now... your gravel landscaping may need to relax a bit... while the fig is rooting...
Where the top is resting on the concrete? Maybe a flat tray of soil under the branches and cover limbs with a bit of mulch...
It might even be possible to get ripe fruit from the limb if you aren't over hasty about cleanup.
I certainly wouldn't be attempting to "balance" the bush until after I got to pick the fruit...
Figs are kind of prone to these small disasters... they don't like being tree formed.
