You cannot imagine a playground without a proper sandbox. Our sandboxes are made of dry glued wood and damp-proof plywood or hardwood. To prevent sand mixing with soil, the bottom of the sandbox is decorated with geotextile. Every sandbox comes together with a net cover, which should be used when children are not playing in the sandboxes. The net cover protects sands from different rubbish and “souvenirs” left by dogs and cats.
