Hubbell Underground Enclosures

June 24, 2024

Hubbell provides three different options for underground enclosures, each catering to different design preferences. These options include Quazite^® monolithic polymer concrete, Quazite^® FRP fiberglass-reinforced polymer, and PenCell^® HDPE enclosure products. Our wide range of products is designed to meet your specific application needs. All three brands are manufactured with Hubbell’s commitment to quality and performance, and each brand is made from a different base material, offering unique advantages.

Quazite Enclosures

Polymer concrete is made from select-grade aggregates in combination with a polymer resin system. When combined through a process of mixing, molding and curing, an extremely powerful cross-linked bond is formed. Precast polymer concrete is reinforced with fiberglass to give it additional strength and rigidity.

Quazite FRP Enclosures

Fiberglass-reinforced polymer, also called FRP, is a special combination of polymer concrete and fiber-reinforced polymer. This hybrid construction, formed from an FRP shell and a polymer concrete ring and cover, delivers a high strength, lightweight, abrasion-resistant product that is protected from ultraviolet rays.

PenCell Enclosures

Fiberglass-reinforced polymer, also called FRP, is a special combination of polymer concrete and fiber-reinforced polymer. This hybrid construction, formed from an FRP shell and a polymer concrete ring and cover, delivers a high strength, lightweight, abrasion-resistant product that is protected from ultraviolet rays.
