Natural Surface Blocks
                    
                        Natural Surface Porphyry Blocks are obtained in the sorting phase and are used to 
create retaining and containment walls as well as to cover them. They have a natural surface, are irregular in size and have rough sides and widths of between 10 and 20 cm. The surface finish which is very level with narrow, deep spaces in between makes laying patterns very fluid and uniform.
