PRO-RING is the only manhole grade adjustment system made from Expanded Polypropylene (EPP). PRO-RING products provide a proven alternative to concrete grade or adjustment rings. The material is renowned for its ability to stand up to the harshest of conditions without damage or deformity for many years.

It usually takes four men to lift a concrete grade ring, which can result in possible injury; however, a 6-inch PRO-RING weights only 14 pounds and eliminates that hazard, helping to reduce worker injuries.

The PRO-Ring system has rings that nest together that include a finishing ring and a slope adjustment ring for a precision fit, making it easy for one person to install the system in just minutes.

PRO-RING products speed manhole installation and repair dramatically, allowing the site to close for only one day and reducing overall cost from 20 to 30 percent based on conditions. No water, sand mortar or bricks are needed, just a few simple tools. 262.542.8153, www.cretexseals.com
