      No, it’s just polished. Epoxy would just rub off over time. With cement, it just gets more smooth with more use.

      They also don’t break down like the plastic or metal ones so some of these structures are like 15+ years old. I saw one that was like 40+ years old that was just made on a hill.

        Well cement will wear down to the aggregate (the little rocks), which will wear at a different rate. Maybe they use a mix without it.

          Ya, no rocks. Next time I take my kid to the park, I can take a photo of the older slides. It wears are noticeable . It’s quite an amazing idea to use cement.
