My advice would be to use a proprietary weed killer – one that claims to kill the whole weed, including the roots. Follow the manufacturer’s instructions re solution strength for best results. Once the weeds have died away, seal any gaps with fresh cement.

Weeds being weeds, will inevitably return (that is the nature of weeds) - regularly apply some form of weed killer to stop their growth (as soon as they start to appear), otherwise they will break up the concrete – making it easier for more weeds to grow.
