Questions
What is inflow and infiltration (I&I), and why is it a problem?
I&I refers to water entering sewer systems through manholes, pipes, and other openings. This excess water increases treatment costs, strains infrastructure, and leads to environmental hazards and higher customer bills.
How do Cretex products reduce sewer system maintenance costs?
Our seals and adjustment systems prevent I&I, reducing wastewater treatment volumes, extending infrastructure lifespan, and minimizing repairs. Pro-Ring installations alone cut costs by 20–30% compared to concrete rings.
What warranties do Cretex products offer?
We provide 25–50-year warranties on all products, reflecting their durability and performance. No warranty claims have been filed since our first seal installation in 1981.
Can Cretex products be installed without specialized tools?
Yes. Most systems require only basic hand tools, eliminating the need for torches, primers, or heavy equipment, making installations faster and safer.
Are Cretex solutions suitable for both new and existing infrastructure?
Yes. Our products are designed for new construction and rehabilitation projects, ensuring compatibility with diverse manhole and pipe configurations.
How does Pro-Ring improve safety during installation?

Report
I'm just a homeowner and I called CRETEX because I needed a seal for one manhole cover to stop smells coming from a septic tank. Spoke to Kevin Lindner and he kindly mailed me a length of seal and a tube of butyl adhesive - no charge. Kind, generous and helpful, you can't ask for more. Thank you Kevin and Cretex.
