GeoKrete geopolymer corrosion-resistant structural repair mortar from Quadex is ideal for rehabilitating deteriorated sanitary and stormwater sewer structures. It quickly and cost-effectively restores structural integrity to corroded manholes and other underground structures. It’s a versatile product and can be spin-cast, sprayed or trowel-applied, depending on the need. The formulation is comprosed mostly of recycled industrial byproducts. It cures through polymerization instead of hydration, resulting in a strong, quick-setting repair mortar with exceptional chemical resistance. 870/688-7100; www.quadexonline.com.
