Restoration of Deteriorated Overhead Water Tanks (OHWT)
Technical Guidelines for Structural Rehabilitation & Waterproofing
Executive Summary: Restoring an aging, leaking overhead water tank requires specialized engineering methodologies beyond conventional surface plastering. This paper details comprehensive rehabilitation workflows: high-pressure water jetting, rebar passivation with zinc-rich primers, structural micro-concreting, low-viscosity epoxy injection grouting of construction joints, and application of certified non-toxic, food-grade elastomeric waterproofing membranes.
