Zeal Pavers & Tiles Interlocking Paver Block Dealers are made from a very dry mix of gravel, sand, cement and color. Interlocking Paver Block is a type of paver. This special type of paver, also known as a segmental paver, has emerged over the last couple of decades in the India as a very popular alternative to brick, clay or concrete. Since there is very little water, the mixture is moved on conveyor belts and then funneled into the paver mold. The interlocking comes from the fact that each stone cannot move independently from its neighbor. In fact there are two important aspects of an interlocking paving stone job that keeps the pavers interlocked. A press is inserted into the mold and vibrated at the same time. The high pressure and the vibration cause the water to set the cement and create a bind between the aggregate. When the mold is moved away, the pavers are in their finished state. When one thinks of interlocking paving stones one often gets the idea of dog bone shape stones that fit together like a jigsaw puzzle. That is not the case at all.
