Fit Semi-recessed basin to Corian

[smallsteve1]

I’ve been looking at various basins to fit on a Corian worktop and I note that many require affixing with screws into the worktop. Thing is, you wouldn’t do this with Corian and so I wonder what the way forward is?
Is it the case that you just rely on silicon, or perhaps you glue batons to the underside of the worktop and screw into those? TIA

I've had baths stay in place, off the floor when legs removed during rip out, just by the silicone around the edge to the wall!
