Short of pouring concrete slab over it, nothing seems to work as weeds will
grow back in a few weeks, few days if we have rain. Then even with a
concrete slab, weeds will grow in the control joints or in the cracks.
Neither weed wacker, tiller or poison works as weeds will come back in a few
weeks. Weeds growing under and above no weed fabric, LOL. Put in two layers
no weed fabric, the commercial stuff, only works if there is enough bark or
mulch blocking off the sunlight. Bricks and patio pavers, weeds growing
between the joints.

What is a good way to control weeds and what works for you?
