Cobblestone is a natural building material based on cobble-sized stones, and is used for pavement roads, streets, and buildings. In England, it was commonplace since ancient times for flat stones with a flat narrow edge to be set on edge to provide an even paved surface.
Pavers come in a vast variety of shapes/styles, colors, and textures. Since we are comparing pavers to flagstone, the great thing to note is that Belgard (an Oldcastle Company) manufactures a paver, called Mega Arbel, which is intended to replicate the look of natural flagstone.
Rubber paving has been used on running tracks, and other applications in Europe for over seventy years. It was introduced in North America a little over 25 years ago. Over the past 10 years rubber has been making its way into residential applications like driveways, sidewalks, strata apartment entrances, and staircases.
Travertine is often visibly porous, giving it a more natural, textured look. However, when sanded down and sealed, travertine tiles are smooth and suitable for flooring or as shower tiles. This stone is relatively soft and absorbent, so it requires a few coats of sealant to prevent debris from penetrating the stone.
