Plastic-lined concrete SEWERAGE PIPES With a country in constant development, be it new commercia l or resident ia l projects or the maintenance or upgrading of existing roads, pipes and stormwater systems, a crucial factor is the application of water and sewerage systems and related products that offer developers and local municipalities the longevity and high quality required. With a history spanning over 100 years, CMA member Rocla has been a leader in the manufacture and supply of sewerage and water systems and has worked with local municipalities and civils contractors throughout South Africa. The technical expertise and assistance that Rocla offers in the water and sewerage sectors, in particular, put it in a good position to assist on projects from inception to completion. One of the flagship products from Rocla is its reinforced concrete pipe with HDPE lining, which offers sewerage projects the same advantages as a conventional concrete pipe or a plastic pipe in that it maintains its shape under load and is resistant to acid attack. Exposed concrete in the joints of a pipeline need to be protected against corrosive gases and Rocla has designed an HDPE capping strip which is welded over the joint of the pipe after installation.
