Our paving stone pool deck and patio is nearing completion but the joints have not been filled yet. A neighbor recommended that I talk to the contractor about using polymeric sand. He said that using polymeric sand will result in a much more stable patio and will stop weeds from growing in the joints.
I just got done browsing the paving stone manufacturer's web site and they have a line of polymeric sand that they sell. I also watched a video on the website showing the correct installation method of polymeric sand with their paving stones. I have mentioned this to my contractor before and if I remember correctly, he said that it would prevent drainage between the stones (which is something you want). I would like some opinions and pro's/con's before I talk to the contractor again about this. If this is a money issue for the contractor, I would rather pay an extra now to save me years of weeds and washed out joints later on.
