GeoKrete geopolymer from Quadex is a corrosion-resistant structural repair mortar for the trenchless restoration industry. It can be used for rehabilitating deteriorated stormwater and sanitary sewer structures, helping restore structural integrity to corroded and deteriorated manholes and pipes and other underground structures via spray applying or centrifugally cast application processes. It is synthesized mostly of recycled industrial byproducts and cures via polymerization instead of hydration, yielding a strong quick-setting repair mortar with chemical resistance. 870/688-7100; www.quadexonline.com.
