We make more then just liners for Manholes. Manhole Rehabilitation is our primary focus, but our products have applications throughout municipal and industrial facilities. We have products to rehabilitate and protect wastewater treatment plants, lift stations, secondary containments, cooling tower basins... and more.

We manufacture a wide range of products that we divide in to four classes:


Our Cement materials product line, PerpetuCrete™ offers a number of great cements to restore structures that are exposed to harsh environments, and it is our newest product line.


Our epoxy coatings and mastics product line, PerpetuCoat™, offer simple solutions to protect manholes lift stations, wastewater treatment plants and similar structures from corrosion and abrasion.


Our cured-in-place liner, the PerpetuWall Lining System™, offer the highest level of value and protection for structures. PerpetuWall offers complete protection from infiltration corrosion while improving the host structure's structural integrity. It is offered only to Certified Applicators and can be use in many ways beyond just a full depth manhole liner.


Resins are at the heart of all or epoxies and our PerpetuWall Lining System™. We offer our expertise in resins in the form of PerpetuSet™.
