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.
