Armorock Polymer Concrete

Armorock Polymer Concrete, operating from Boulder City, Nevada, is the world's largest manufacturer of precast polymer concrete structures for sanitary sewer and wastewater collection systems. The company's polymer concrete formulation replaces Portland cement with isophthalic polyester resin blended with sand and conventional aggregate, yielding a material that exceeds 15,000 PSI in compressive strength and 3,000 PSI in flexural strength while remaining entirely immune to hydrogen sulfide corrosion. Armorock structures require no secondary coatings, liners, or odor control systems because the non-porous polymer matrix provides nothing for sulfide-producing bacteria to colonize. The product line includes new polymer concrete manholes from 48-inch through 144-inch diameters, rehabilitation inserts for restoring existing 48-inch and 60-inch manholes, wet wells in round form sizes from 4-foot to 12-foot diameter, lift station structures, and precast bases manufactured with robotic precision to eliminate cold joints. Armorock backs its structures with an industry-leading 50-year warranty against H2S corrosion damage and projects a design life exceeding 100 years in corrosive environments. The company holds U.S. Patent No. 9,567,760 for its polymer concrete manhole and structure designs and complies with ASTM D6783 standards. Distribution is supported through partners including Sancon Technologies for rehabilitation inserts and Romtec Utilities for wet well installations.
