Does anyone know the best way to fill the joints between concrete driveway slabs? I packed the joints with sand and used sikaflex that I got from the homeless despot and put it down last summer, made sure the concrete was completely dry for several days before and after, this summer I've noticed the sikaflex has cracked at a few joints. Is there a better product to use for sealing the joints? via /r/DIY http://ift.tt/2tJf3ph
