How are weeds still growing?

Hey, I need some advice. I recently hired someone to cover my yard with weed cover and poured rocks on top hoping to stop weeds from growing. To my surprise, weeds are still growing and it’s literally puncturing the weed cover. How is it possible? Any advice? Thank you
