With ongoing uncertainty in plastic pipe supply, many stormwater projects are reviewing material options.
Concrete pipe is a viable substitute for plastic in 225, 300, 375 and 450mm diameters, across all types of stormwater construction, when planned early and assessed against project requirements.
Plastic pipe sizes commonly specified in stormwater applications can often be replaced with concrete pipe in equivalent diameters, subject to standard design and installation considerations.
Our team can help confirm suitability and provide guidance on handling, installation, cover, access and methodology. Weāre also happy to support customers with training to ensure concrete pipe is specified and installed correctly.
