Home Renovations Interlock Paving - It Was Good Enough For The Roma | Page 12

Conclusion
As we have seen it is the sand between the rough surfaces of the stones that creates the
interlocking through introducing the high friction that restricts movement of the stones
against one another, which effectively locks them in place. However that is also ironically
the one weak point of the interlocking paver design in so much as over time the sand leaks
away through exposure to the elements such as rain and wind. With the loss of sand comes a
loss of strength and cohesion therefore the sand must be regularly replenished to maintain
the overall structural integrity. However that is a single flaw in an otherwise near perfect
engineering structure that has stood the test of time over the centuries.
