Disclosed is a cover for a utility vault and a method for making such covers. The cover is formed from fiberglass reinforcement layers and a polymer mix matrix. The reinforcement layers include a bottom reinforcement layer, one or more edge reinforcement layers, and a top reinforcement layer. A first portion of the edge reinforcement layer overlaps a portion of the bottom reinforcement layer and a second portion of the edge reinforcement layer overlaps a portion of the top reinforcement layer. The reinforcement layers are formed from fiberglass fabric and may include fiberglass layers whose fibers are oriented quadraxially. The polymer mix impregnates the fabric layers and forms the bulk of the cover. The polymer matrix bonds the reinforcement layers so that forces applied across the top and bottom layers are communicated to the edge reinforcement layer. The polymer matrix includes a thermoset polymer resin and an expanded glass bead filler.

A bulk material shipping container including a pallet, a compartment mounted on the pallet, a material unloading assembly, and a material loading assembly.

A subgrade vault system with a locking lid assembly is provided. Specifically, a subgrade vault suitable for housing utility and similar equipment is provided, the vault comprising a main body portion, a cap, and a lid that may be selectively secured with one or more rotatable locking mechanisms to prevent or deter unauthorized access to vault contents.

A bulk fluid storage container includes a frame assembly having a lower rectangular frame, first and second wheel assemblies extending from opposite ends of the lower rectangular frame, and an upper rectangular frame member arranged in spaced relation to the lower rectangular frame member by a plurality of vertically extending posts. The bulk fluid storage container also includes a fluid storage vessel having first and second end walls held in spaced relation by first and second side walls, a top wall and a bottom wall, which defines a fluid storage volume. A baffle assembly having a plurality of baffle plates is disposed in a space relationship in the fluid storage volume. The frame assembly provides an exoskeletal structure which surrounds the fluid storage vessel and is configured to support a second bulk fluid storage container in a vertically stacked relationship.

A multifunction tank access device is configured for connection to a storage tank capable of storing crude oil that has an opening for a conventional thief hatch. The multifunction tank access device has a lower assembly with an isolation valve, and an upper assembly removably connected to the lower assembly. The upper assembly includes a central housing, a pressure relief module, a vacuum relief module, and a tank access module. In some embodiments, at least a portion of the multifunction tank access device is constructed from a material that melts at a temperature below 450° F.
