Instead of connecting the pavers by pouring grout between the joints as one would with tiles, sand particles are spread over the pavers and tamped down. The sand stabilizes the Interlocking pavers, yet allows for some flexibility. This type of Concrete Paver Block pavement will absorb stress such as small earthquakes, freezes and thaws, and slight ground erosion by shifting each tile slightly. Therefore, they will not crack or buckle like concrete, though bad weather may make potholes.

The special tools needed for installing interlocking pavers are vibrating compaction machine or "Vibra Plate" and Shear Cutter. The former is used to compact the base material to 90% density minimum and also to set and interlock the pavers into the sand bed. The latter is used to cut the pieces to fit at corners and edges. The sand does not easily wash out with rain or garden hose water and a sealant can be spread on to further lock the sand.

Standard thicknesses are 60mm (for light traffic) and 80mm (heavy traffic). 50mm too is common in some countries like Pakistan (used for footpaths etc).

Benefits of paver over asphalt and poured concrete include high compressive strengths (7000+psi as per BS and 8000+psi as per ASTM codes), pleasant look, time saving, easy removal and relaying.
