​Colossal Concrete Products produces large diameter vertical cast In the Wall Joint Jacking pipes. This process is used worldwide and is acknowledged to be ideal for concrete pipe manufacturing. All the manufacturing processes are done under carefully controlled conditions using advanced technology and equipment. Concrete pipe jacking is a method of installing pipelines without disrupting existing surface facilities or activities. With the increasing growth in South African cities and towns and the consequent need to refurbish, renew and upgrade existing services, pipe jacking is seen to be a growing industry. Although the basic methods of concrete pipe jacking are similar for all pipeline applications, South African contractors have developed their own individual techniques to achieve accuracy during jacking, to lengthen the jacking distance and to control varying ground conditions. An HDPE liner can alternatively be added to the bore of the pipe to prevent the sulphuric acids from encountering the concrete surface.
