Crammix has made giant leaps in recent years, concentrating on products of high technical specifications. The entire production is under consistent review with the upgrading of the tunnel kilns, installation of drier extensions, as well as a new automated setting and preparation plant. It is because of these technological advancements and growth that Crammix is acknowledged as a technological leader in Clay Brick production and one of the major economic players in the Western Cape.

The manufacture of Crammix Clay Bricks involves a great deal of engineering expertise and a touch of art. The clays are mined right next door to the factory, and are crushed, mixed with water, blended for colour, shaped and formed, and then cut by means of a computer-controlled extruder and cutter and then stacked on kiln cars for drying. These are then automatically fed into the drier and tunnel kiln, on two trains of 36 kiln cars each, spanning 100m in length. Between 3 000 to 5 000 brick units are stacked on each car depending on the product type. After drying and firing at 1 120 degrees centigrade, they are cooled, sorted, strapped and branded ready for delivery on site.
