The marine concrete ballast moulds of Moldtech are made up of three removable sides and one fixed bottom, when assembled together, give shape to the element to be manufactured.
Since PE pipes float, even when filled with water, concrete ballasts are incorporated in order to be able to submerge them. In general, these ballasts are made up of two pieces of reinforced concrete with different dimensions and geometric shapes, which are attached to the pipe by means of screws and nuts. In their inner part they normally have two EPDM-type synthetic rubbers to prevent damage of the pipes.
