A concrete Press machine utilizes only hydraulic pressure to compress the concrete and squeezes the water out of a semi wet concrete mix to form a very strong, dense concrete product. The advantage of this type of process is the finished product is an extremely high strength dense unit. Because the products are so strong and dense the units are able to have a wide variety of post treatments applied to them. This can include grinding, polishing, engraving, shot blasting, flame surfacing or sand blasting surfaces. Another unique advantage of this method of making slabs is that the products can emulate the textures, finishes and blended colors of natural stone or travertine stone. The Press system is the best machinery system for producing these unique slabs, kerbstones, and high strength roof ballast slabs. These types of concrete products are normally sold at a premium price because of their superior quality and long lasting value.
