Default Whats the best way of joining 2 concrete slabs - if there is one

Whats the best way of joining 2 concrete slabs - if there is one

I have laid a slab of concrete in the garden, and I need it another 12
inches wider.

OK I can put some shuttering up and lay some more concrete, but how do
I ensure that the joint is always sound and does not give ??? Do I
drill some holes sideways into the original slab and put in some metal
bars or screw in some large dia screws and leave the heads protruding
a few inches.

Or am I worring too much.

Depends what you are using it for!
Epoxy in some 12" rebar half into each, at 600mm intervals. Or screw
in some 'Multi Monti' type bolts (Screwfix).
