Paving stones are in use since early A.D. Roam times. They have gained popularity here in India since early 90's.
The initial cost is very comparable but where interlocking paving stones have an advantage over the other paving materials is its life expectancy, interlocking paving stones will last a life because of its high strength (8000psi) compared to placed concrete which is 2500psi. They also have the ability to flex and move because of the joints between them. Other paving materials are susceptible to cracking and therefore have a less life expectancy.
No, Interlocking Paving stone surpass the standards for slip resistance established by the American disabilities act.
No, all weeds and vegetation need sunlight to grow, growth in between interlocking paving stones occur when airborne spores infiltrates the sand joint, using polymeric sand and/or sealing joints will virtually eradicate weed growth.

3. Limits vegetation and weeds growth.
4. Helps with general maintenance.
Yes, with clean, fine sand the sand should be dry sand so it will flow freely into the joints.
In 4” (200mm) layers to achieve the maximum density and load bearing capacity. Each layer will require several passes of a compactor to achieve this.
Yes, an edge restraint around the perimeter of the pavers is essential for eliminating horizontal creeping of the pavers and loss of bedding sand.
Yes, you can be assured of replacement of pavers. They can be easily removed and/or replaced.
