Meeting Them


Corrugated Vaults are for use with large equipment which have traditionally been installed in large precast concrete vaults. They come with preinstalled lifting provisions, and because they are so light, they can be easily set in place using only an excavator.
GlasMasters Boxes are designed and manufactured specifically for each individual application. Whether it is used as a valve box that only receives pedestrian traffic, or as a junction box that receives non-deliberate vehicular traffic, you can be sure that the GlasMasters Box can handle the load for many years to come.

These heavy duty steel covers have a T-style design which allows them to work even if the previous enclosure has been damaged and a regular drop-in style lid no longer works.

GlasMasters manufactures a wide variety of underground enclosures serving various different utilities. We make small enclosures that are typically used for residential water meters, traffic signals and electrical junctions, as well as large enclosures that are typically used for commercial water meters, fiber optics and electrical junctions.
Our enclosures use the best materials along with the best designs, and manufacture them with the highest quality. All GlasMasters boxes are made using Polymer Concrete in combination with Fiberglass. These materials offer superb strength-weight ratio and maintain that strength over time. They are not susceptible to the elements of the environment, unlike traditional precast concrete or plastic.
