![]() SPECIFICATIONS: FIBERGLASS POLYMER CONCRETE- Pull Box, Junction Box, Hand Hole, Splice Box, Vaults and Transformer Pads![]() SPECIFICATIONSPolymer ConcreteThe pull/splice box ring and cover shall be constructed of polymer concrete consisting of sand and aggregate bound together with a polymer resin. Internal reinforcement may be provided by means of steel, fiberglass, or a combination of the two. The polymer concrete material has the following minimum allowable properties:
Ultraviolet Exposure: Tested in accordance with ASTM G-53 using an U.V.A. 340 bulb. FiberglassMATERIALS: BASE Compliance with All Industry Standards for Load RequirementsThe standard product line is designed and manufactured to perform to and comply with the following industry standards for loading:
Polymer concrete/polymer concrete-fiberglass products are not intended for use in constant traffic areas. Product Test Procedures The following test methods have been used in evaluating the physical and chemical properties of the hybrid fiberglass/polymer concrete product line:

The aggregates include silica, quartz, granite, limestone and other high quality material. Conventional Concrete uses a combination of cement and water for the binder. In polymer concrete the binder is a high strength, corrosion resistant, thermosetting resin. This resin system requires a curing agent (catalyst) which when combined with the resin, transfers the resin and curing agent from a liquid to a solid (thermoset polymer) which bonds to the aggregate, various fillers and internal reinforcement. The polymer concrete is reinforced with fiberglass for superior strength and rigidity. Why choose polymer concrete enclosures and pads?
