Roundup is absorbed through the leaves of what you spray it on. It dries quickly and will not hurt anything else even if absorbed into the ground.
One exception. There is a type of roundup that in addition to killing the weed will prevent more weeds from sprouting for a year. This type can damage root systems if used a lot in one area.
