unistonePlastipro’s Unistone Edging are seven (7) feet long, and they can accommodate any landscape design, straight sections, curves, and even a complete twelve (12) inch radius.

They are easy to install with standard 8’’ or 12’’ spikes.The highly aerated structure of Plastipro’s Edging provides favourable growing conditions for grass roots, while their special inclined design keeps a constant pressure and extra support on the pavers, preventing dirt accumulation in between the edges and the stones. Manufactured in a Black super though high impact copolymer specifically designed for this application, they are extremely resistant to cold temperature and are ideal for driveways pathways and patio.
