I live in NJ. Wooden dividers in my concrete patio have rotten over time (about 25 years) and weeds are growing in the gaps. Some of the separators have heaved above the surface. Can I pull out all the dividers and replace it with bricks or something ? The gap is about 1.75-2.00 inches. Is there any other option? Please note that I have no previous experience, this would be my first project. Any suggestions / advise is welcome.
Thanks
