We also work regularly with civil engineering and construction companies to provide tailored pre-cast concrete solutions such as retaining wall panels, bridge parapets, pre-cast beams and arch tunnels. If you have a special project needing pre-cast concrete, we can supply your needs.

Committed to excellence

From our base in Angle Park, South Australia, we have made it our life’s work to deliver outstanding pre-cast concrete products. We are committed to excellence, not only in our manufacturing techniques and processes but through every interaction we have with our customers.

We are South-Australian owned and operated and we service all parts of metropolitan Adelaide, rural and regional areas within SA and the Northern Territory.

Ri-Industries was the first South Australian company to combine the manufacture, delivery and placement of septic tanks. With engineering experience that spans over 70 years, we have developed a number of associated products to deal with sewage and waste, most notably our Ri-Treat system. Our unique design has become a leader in South Australia for the management and treatment of waste water.

All of our products are ‘over-engineered’. That is how we strive for 100% excellence. Plumbers describe our products as “second-to-none” and “the best in South Australia”. We are proud of our stand-out quality of product and service. This is further backed up by our on-time deliveries, knowledgeable sales team, after sales back-up services and a manufacturers warranty.
