Frequently Asked Questions:

Why should I use lightweight concrete grade rings?

• Compatibility: The product meets ASTM C-478 - the nationwide standard specification for precast concrete manholes. Our lightweight grade rings are designed to be used to make grade adjustments by placing them between the manhole cone and the cast-iron ring. By specifying our product, you will receive manholes that meet the full extent of the standard precast manhole specification used throughout the U.S.

• Installed Cost: Our lightweight concrete rings cost less and install faster than plastic grade rings.

• Storage Life: Unlike plastic, lightweight concrete is unaffected by ultraviolet rays. Store our product in your yard as long as you like - it will not become brittle or crack with age and exposure to the elements.


• Near zero infiltration: When installed properly using an asphalt-type strip sealant below each level, our lightweight rings allow miniscule amounts of infiltration into the manhole.

• Traffic rated: Use our 4000 psi H-20 rated lightweight grade rings in either paved or unpaved areas.

• Ease of Installation: By utilizing lightweight concrete, the weight of a single 2" tall ring is only 66 pounds - easily handled by installation personnel when installed properly using an asphalt-type sealant. Weights of the 1" and 1.5" rings are even less!

Is the product compatible with other manufacturers' products?

• Yes - our lightweight rings are compatible with all locally available precast manhole cones. In addition, the product was designed to work with all locally specified cast-iron rings and covers.

What type of reinforcing is provided in your lightweight grade rings?

• We provide circumferential steel reinforcing per ASTM C-478 and add
additional fiber reinforcing to the mix to increase the concrete's durability.
