Both split concrete blocks and smooth decorative blocks are used for load-bearing wall construction. The smooth-textured blocks can be left exposed due to their perfect finish. Split-finish blocks are highly decorative elements, ideal for building all types of facades and fences. White and colored pieces are treated with a water-repellent coating. Pillars are essential components in wall construction, as they connect different sections, providing strength and stability to the entire structure. They bear a significant portion of the load and transfer it to the foundation.
