The only manhole grade adjustment system built of expanded polypropylene, PRO-RINGTM (EPP). PRO-RINGTM (EPP) is the most sophisticated concrete ring alternative manhole grade adjustment device, PRO-RINGTM products offer a superior replacement for concrete grade or adjustment rings.
EEP has a reputation for withstanding even the most extreme circumstances for many years without being harmed or deformed. These lightweight rings, which are installed on tens of thousands of manholes and catch basins across the United States and Canada, are recognized for their remarkable strength-to-weight ratio, toughness, chemical resistance, and long service life under the harshest conditions.
Benefits of PRO-RING
Lightweight- Two to four men are often needed to raise a concrete grade ring, and each one runs the danger of suffering a back injury. Just 14 pounds make up a 6″ PRO-RINGTM. The PRO-RINGTM method eliminates the risk that concrete rings can fracture and inflict harm, helping to lower compensation claims.
Efficient- The PRO-RINGTM system is simple to install by one guy in a matter of minutes. Every time we perform, people are in awe. The rings fit precisely together and have a finishing ring and a slope adjustment ring.
Fast and Cost Effective- PRO-RINGTM solutions significantly speed up manhole installation and maintenance, allowing the site to be shut down in a single day and lowering overall cost by 20% to 30% depending on the circumstances. There are no bricks, mortar, or water.
