k5 karcher pressure washer in action - weed problem

How we put this right , basically weeds sprayed with glyphosate roundup weedkiller a week before hand.
The weeds then pulled out easily then jet washed and when dry brushed dry kilm sand into the joints
Glyphosate-based herbicides all work on the same biochemical principle - they inhibit a specific enzyme called EPSP synthase .
Without that enzyme, plants are unable to produce other proteins essential to growth, so they yellow and die over the course of several days or weeks. A majority of plants use this same enzyme, so almost all plants succumb to glyphosate.
