The term ‘sawn paving’ describes a contemporary format of natural stone paving available from some stone suppliers.
Whereas riven paving is created by splitting the stone where it naturally splits on the seam, sawn paving is machine made.
How is sawn paving made?
Sawn paving is created on a machine where each of the 6 sides of a paving slab, i.e. the 4 edges and the 2 surfaces, have been machine sawn.
This creates a perfectly square or rectangular slab with a calibrated (regular) thickness. Each slab has straight edges and a flat top surface. The top surface can then be either sandblasted, brushed, honed or flamed for a final design finish.
The surface finishes applied to sawn paving
Sandblasting: the surface is blasted under high pressure with grains of sand. This creates a slightly textured surface, which is grainy to the touch.
Honed: this surface finish is created by polishing the surface. The result is smooth to the touch with a low sheen.
Flamed: the surface of granite paving can be torched with a flame. This causes crystal particles on the surface to burst, creating an overall roughness or pitted surface.
Brushed: The slab surface is brushed with diamond coated nylon bristles which take away some of the softer particles from the surface. A slightly textured surface is achieved.
Acid Etched: Limestone paving reacts with acid. The treatment of the surface with acid creates a nonslip texture by burning away a little of the surface.
