Choose the correct underground tank detail in seconds
Use our free Selector Tool to match your Promax underground tank to a certified installation drawing.
Installing a tank below ground is never one size fits all. Soil type, traffic loading and cover depth all influence the detail you need. Rather than sift through 23 drawings, let the Selector Tool do the work for you:
• Filters every certified Promax installation option
• Aligns with New Zealand load cases from light landscape to HGV traffic
• Flags minimum and maximum burial depths
• Gives you an instant download link for your drawing register
Answer a few quick questions and the calculator will present the exact detail for your site. No guesswork. No delays.
*The tool may take a few seconds to load. Thanks for your patience.*
