The polished look of Courtstone brings a luxurious, old-world elegance to driveways and walkways, with Ultima™ which provides up to four times the strength of conventional poured concrete. Using Reala™ Technology, the unique shapes of Courtstone were cast from real European cobblestones, but manufactured with a consistent base for efficient installation and superior interlock. It’s a look that has remained popular for centuries. The stone’s non-linear shape means it’s possible to create smooth looking curves without cutting Courtstone. This, in combination with its rich color palette, also makes Courtstone a frequent choice for borders and banding accents.
