Geotree - LOCTITE GeoSpray HCE Proves Its Worth By Cutting Installation Time By 25%

Large-diameter interceptor sewers often face extreme structural degradation from spalling concrete and exposed reinforcement, especially in highly corrosive environments. Traditionally, rehabilitating these vital assets required a multi-step process: first applying a structural liner, then adding a secondary protective coating to resist chemical attack. This phased approach, while effective, extends project timelines and increases labor costs.

Recent advancements in geopolymer technology have streamlined this maintenance cycle. By integrating structural reinforcement and high-level corrosion resistance into a single-step spray application, utilities can significantly reduce installation time—often by as much as 25%. This specialized mortar adheres aggressively to existing substrates, filling voids and creating a smooth, impervious finish that stands up to abrasive influences and corrosive fluids. Eliminating the need for a secondary post-coat allows projects to move faster without sacrificing long-term durability or hydraulic performance.
