per my other thread, I've noticed something with the increased melt we've got. the rough, unfinished concrete on either side of my trench drain is basically dissolving into concrete coloured sand!!! I can take my bare finger and poke into it.
what causes this??? it is literally vapourizing and completely disentigrated! basically well formed mounds of sand now....same goes for the forming that held the rails in place. I can scrape it away with a pain scraper!!
any thoughts on what caused this, and ideas on how to prevent MY repair from doing the same in 1 season??
