Polymer Concrete Enclosures

Polymer concrete is the material of choice where load-bearing performance and long-term durability are non-negotiable. Our polymer concrete assemblies combine a high-strength concrete matrix with polymer binders to produce enclosures that resist cracking, chemicals, and heavy traffic — even in H-20 and Tier 22 load environments.

Fiberglass Straight-Wall Enclosures

Our fiberglass straight-wall handholes offer a lightweight, corrosion-proof alternative to concrete — without sacrificing strength or longevity. The straight-wall design allows for efficient stacking and straightforward installation, making them a popular choice for telecom and fiber network builds.

Fiberglass Flared-Wall Enclosures

The flared-wall configuration is engineered for installations where lateral soil pressure is a concern or a wider base footprint improves stability. The outward taper of the walls distributes underground loads more effectively, reducing the risk of deformation over time in challenging soil environments.

Not Sure Which Product Is Right for You?

Our team has decades of experience helping engineers, contractors, and utilities select the right enclosure for every application. Whether you need a compact handhole for a fiber splice point or a large vault for a substation, we’ll help you find the right fit.
