Zigzag Paver Block

Zigzag paver blocks are a particular kind of paver with a zig-zag interlocking pattern. They are sometimes referred to as concrete interlocking blocks or interlocking concrete pavement (ICP). 

They are often used for exterior hardscaping projects such as patios, driveways, and walkways.

Usually composed of concrete, it provides strength and endurance to resist weather, foot traffic wear and tear, and even some vehicle weight (depending on the thickness and design of the particular paver block).
