Square & Rectangular Pro-Ring

manhole grade adjustment

Cretex now offers square and rectangular Pro-Ring. Manufactured from the engineered polymer expanded polypropylene (EPP), these rings meet the AASHTO HS-25 requirements. EPP is known for its exceptional strength-to-weight ratio, chemical resistance, durability and long service life. These products are approximately 1/20 the weight of concrete grade rings, which makes them easy to handle and safe, and reduces the risk of worker injury.
