ERMATIC® Machined Modular Solution

The ERMATIC^® custom modular multiple cover system is a highly engineered range of access covers designed for a wide variety of underground services. It is engineered to perform in tough environments where excessive loads and frequent need for access are par for the course. With every unique customer project/application, we design and build a specific product customized to fit any underground vault dimension or cover configuration. The covers and beams are removable, yielding a full clear opening. The ERMATIC range leverages the global engineering and design experience within EJ to enhance ergonomic design and security.

Modular Construction

The use of modular elements gives a vast range of custom sizes. Multiple frame elements (side frames and end plates) are assembled to provide linear openings for even the longest ducts. For clear openings wider than 47 3/16” (1200 mm), ERMATIC units use removable beams supported in wall boxes which are integral to the frames. This allows the construction of units to suit the largest openings.

Benefits

Customizability

Thanks to their modular design, ERMATIC modular systems are customizable products made to accommodate underground structures of almost any size or cover configuration! They are designed to accommodate extreme wheel loads (up to Airport Extra Heavy Duty) and are highly adaptable—covers fit larger openings and trenches of any length. Multiple features and options are available to facilitate safety and ergonomic concerns.

Ergonomics - Ease of Access

ERMATIC modular solutions keeps workers safe. They're designed for easy handling and feature ergonomically designed lift handles and optional assist lift covers. Removable I-beams provide unobstructed access to large clear openings.

Ultimate Protection

The ERMATIC modular solution keeps underground structures secure. These solutions are quiet—precisely machined surfaces fit tightly together, reducing movement under traffic conditions and protecting against damage and debris or aggressive chemicals for underground vaults/trenches. Designers are also able to conceal underground services as the covers can be ordered with the options of concrete infill or pavers to allow blending with the surrounding groundwork.
