Stone paving block is a type of construction material used to create a hard, durable surface for walkways, patios, and driveways. It is made of concrete or stone and is usually rectangular in shape. The term SETT is an abbreviation for sett paving, which is a type of stone paving block that has been cut into small cubes and then laid in a pattern. This type of paving block is often used to create a more decorative look than regular stone paving blocks.
