Common Questions
What is BlackMAX pipe used for?
Iplex lists stormwater drainage, estuarine and ocean outfalls, road culverts, low head irrigation, slip lining, leachate collection and stormwater retention.
Is BlackMAX made in Australia?
Yes. Iplex lists BlackMax as Made in Australia.
What cover does it need under roads?
Iplex states 600mm of cover is required as a minimum under sealed roads and 750mm of cover under unsealed roads. However this can vary with the regulatory authority and a full structural analysis to AS/NZS 2566.1 should be completed to confirm suitability. BlackMAX SN8 pipes are suitable for cover heights of 2 to 10 metres.
Can it be cut and rejoined on site?
Yes. The rubber ring joint is designed for ease of assembly and jointing, and pipes can be cut to length on site and rejoined.
