Traditional cobblestone paving may be directly placed on flat lids, with steel or plastic barrier strips on both sides. Over time, it can become unstable and prone to falling off and warping. Our one-piece molded cobblestone lids are not only aesthetically pleasing but also highly practical, with an easier installation process.
