Armorock Polymer Concrete Structural Insert Introduction

Sewer manhole rehabilitation using Armorock structural inserts is a cost effective, environmentally sustainable permanent solution to the corrosion found in sewers caused by H2S. Unlike coatings and liners which simply act like a Band-Aid over the problem, Armorock structural inserts builds and fortifies the manhole - creating a solid corrosion-proof structure inside the old one. This rehab system eliminates the cost and inconvenience of manhole removal, and with a 50-year corrosion warranty, engineers and owners can sleep well at night knowing the corrosion problems are eliminated in these manholes from here forward because of Armorock and your leadership to specify a sustainable material.
