PRO-RING vs. Concrete Grade Rings

  • SAFETY – It usually takes two to four men to lift a concrete grade ring, each one risking back injury. A 6″ PRO-RING™ weighs only 14 pounds. Where concrete rings break and can cause injury, the PRO-RING™ system minimizes that hazard, helping reduce comp claims.
  • EFFICIENCY – One man can easily install the PRO-RING™ system in just minutes. People are always amazed at our demonstration. The rings nest together and include a finishing ring and a slope adjustment ring for a precision fit.
  • FAST AND COST EFFECTIVE – PRO-RING™ products speed manhole installation and repair dramatically, allowing the site to be closed in one day and reducing overall cost from 20% to 30% based on conditions. No water, sand mortar or bricks are needed, just a few simple tools.
    • Angle ring allows conformity to sloped road surfaces.
    • Cost effective over the long haul.
    • Best Warranty in the industry.

CASE STUDY

Cretex PRO-RINGTM Manhole Grade Adjustment Ring System
Project: PRO-RINGTM Installation Demonstration and Endurance Test
Location: MH# H190029 on Putnam Pike (State Rt. 44) in Johnston, RI

Providence, RI
Installation Date: April 6, 2010

Scope: Reconstruct a deteriorated brick adjustment
area of a sanitary sewer manhole located in a busy
state highway. This deterioration was allowing the
manhole to take on water during rain events which
was washing in sub-grade material and causing the
pavement surrounding the manhole to settle and
crack.
The failing pavement was saw cut and removed to
expose the manhole frame and failing brick work.
The frame and cover were removed and several
courses of the deteriorated brick was also removed
to get down to structurally sound material.

State Rt. 44 carries an average of 18,000 to 20,000 vehicles per day per RI DOT data

Inspection Date: The most recent inspection was conducted on December 6, 2023 after more than 13 years
of continuous service. It is estimated that this manhole has been impacted more than 350 million times
based on the location (driver’s side wheel path) and the volume of auto and multiple axle vehicular traffic
on this road.
