<p>A method for producing paving sections of natural stone has a mould with internal walls defining the required shape (4) of the section. One of the walls is removable, or is on a sliding mounting (8). This enables the paving section to be removed when set. The internal walls are secured by backing braces (5). The operator fills the mould with a base layer of cement/concrete and applies the natural stone in a selected pattern. When the cement has set the movable wall is retracted and the paving panel removed.</p> |
